Environment

One of the major threat the planet faces today, environmental degradation is bound to make life difficult for all the lifeforms, including us humans, sooner or later. Studies reveal that the deterioration of environment is occurring at an alarming rate. In fact, the High Level Threat Panel of the United Nations has enlisted it as one of the ten threats for humans. This issue shares space with problems like poverty, terrorism and civil war in the list, and this itself highlights the fact that we are heading for a certain disaster. What is Environmental Degradation?

It is a process wherein the natural environment of the planet is degenerated to such an extent that the biodiversity and the general health of the planet is subjected to drastic reduction. In other words, this phenomenon can be defined as deterioration of the Earth’s natural surroundings as a result of excessive exploitation of the available resources – these include water, air, flora, fauna, soil etc. The life on the planet is interwoven to such an extent that a decrease in a particular attribute triggers a domino effect on all the other attributes dependent on it.

How is it Caused? ’; Environmental degradation can be attributed to various human activities and some natural processes, with the later having an insignificant share in the same. Most of the resources on the planet are vulnerable to depletion, and the rate at which we are exploiting them have already brought some of them to the brink of exhaustion. Exploitation of the fossil fuels is the best example of this phenomenon. Large-scale exploitation has depleted the fossil fuel reserves across the world, thus leaving us with no option but to find an alternate source of energy.

Other human activities which have been contributing to this environmental issue include urbanization, overpopulation, deforestation, pollution, hunting, etc. What Does it Affect Us? Its effects are becoming more and more obvious in form of all those environmental issues affecting the planet. The hazardous waste let out by the industries tends to contaminate the water bodies in the vicinity, thus leaving the water unfit for drinking.

Similarly, greenhouse gases, such as CFCs and carbon dioxide, let out in the atmosphere have a devastating effect on the environment, thus making the planet vulnerable to a range of problems, including global warming and climate change. On one hand, incessant agricultural activities have resulted in degradation of soil, while excessive deforestation to accumulate the growing population has resulted in degradation of air and water on the other hand. Humans have seldom sacrificed their necessities, but lately exploitation of resources to fulfill these necessities itself is taking a toll on the environment.

How Can we Deal With it? At one point of time, the damage reaches a stage wherein the environment can’t attain the required balance on its own. In such a situation, we humans need to step in, and ensure that the damage is curbed and balance is attained. Simple measures, such as conservation of electricity, use of alternative energy sources, avoiding the use of things that pollute the environment, soil conservation, etc. , can help in saving the environment from the threat of degradation. Environmentalists, the world over, are trying their best to save our environment, and we need to do our bit to make sure that they succeed.

The need of the hour is to identify the causes of environmental degradation, and eliminate them one by one. We need to understand the fact that we are a part of the interwoven life system on the planet, and any problems, like environmental degradation and environmental pollution, are bound to affect us directly or indirectly. Though the disaster is not expected to happen tomorrow or a hundred years from now, that doesn’t mean it will never happen at all. That being said, the onus is on us – the most intelligent species on the planet, to make sure that such problems are kept at bay.

The main causes of environmental degradation are as follow; 1 Industrialization 2 Agricultural development 3 population growth 4 poverty 5 urbanization 6 Deforestation 7 transport development 8 market failure Causes of Environmental Degradation There is no doubt that man has caused environmental degradation. The causes of environmental degeneration are complex and should be addressed to, before it causes complete breakdown of the environment.

When the natural state of the environment is compromised upon it leads to breakdown of the biological diversity and harms the health of the environment. The process of environmental degradation can either be caused by nature itself or it is man-made (which is a fact). If one has to compare the face of earth as it was hundreds of years ago to what it is today, we will see that environment has severely been compromised upon.

When people look at environmental degradation, the intensity of the problem is not actually understood, but it could cause destruction of the human race itself. The causes of this problem vary a lot and it means depletion of the natural resources and disturbances in the natural cycle of things on the face of earth. Root Causes of Environmental Degradation The best case of environmental degradation can be seen in land degradation. There are climatic conditions responsible along with the human activities, which have brought about the degradation.

The effects can be seen in the arid, semi arid and dry sub humid lands. One of the cause is over grazing of land. Along with that the green cover has depleted severely in almost all parts of the world. The forest cover has made way for human settlement. This has resulted in the temperatures increasing with each passing day. Since the forest covers have depleted, it has resulted in large-scale erosion, which in turn, is responsible for loss of nutrients from the soil. This has led the soil to becoming barren and in some cases also sterile.

Since the forest cover has been lost, the winds now blow the top soil from the land, which also leads to degradation of the environment. Pollution is eating away into the environment. Here we are talking about air pollution, where toxic substances have made their way into the air, which has caused the air to become unhealthy. Air pollution is caused by a number of reasons. One of the most prominent cause is vehicle emissions. With each passing day, the number of vehicles are on the rise, which means increase in air pollution. The next cause is release of chemical waste from various factories.

The waste often forms a layer in the atmosphere of the earth, which further affects the environment. In environmental degradation we cannot forget the exploitation of fossil fuels. Since the time fossil fuels were discovered, they have been exploited. This has resulted in the fossil fuel reserves depleting all around the world, hence it has become important to find alternate sources of energy. When the fossil fuels are burnt, they release toxins into the air, which further aggravate environmental degradation. The underlying causes of environment going down way is overpopulation.

The land reserve that is available on earth is finite. However, the demands are ever-increasing due to increasing population. There is only so much, that one can actually extract from the earth. This has led to widespread use of chemicals and other toxins to produce more food to feed the ever-increasing number of people. This has further caused depletion of the earth. With the use of chemicals the biological balance of earth has also been destroyed as the microorganisms have been killed. If one has to see the environmental degradation causes and effects, one will see that entire ecosystems have been destroyed.

The ecosystem is made up of all the living and non living elements. However, when any one of them is destroyed, it leads to the destruction of the entire ecosystem as the balance is lost. No doubt plants and animals form an important feature of the ecosystem, but the microorganisms along with water sources and soil cannot be forgotten either. Industrial waste is known to be hazardous to the environment. The waste can be in the form of liquid waste, which pollute the rivers and cause harm to the ecosystem present in the rivers.

It can also be solid waste, which is not biodegradable and pollutes the environment and leads to its degradation. We have already spoken about the industrial waste emitted into the air. After reading about the causes of environmental decadence, we can say that if the human race has to survive on the face of this earth, it is important that stringent measures be taken up to arrest further deterioration of the environment. One will have to work towards conserving air, water and soil and try to restore balance in the ecosystem, which has been destroyed or is on the verge of destruction.

In other words, one will have to work towards restoring natural habitats and make sure no further harm is done to the environment.

It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. [1] Environmental degradation is one of the Ten Threats officially cautioned by the High Level Threat Panel of the United Nations. The United Nations International Strategy for Disaster Reduction defines environmental degradation as “The reduction of the capacity of the environment to meet social and ecological objectives, and needs”.

Please help us clarify the article; suggestions may be found on the talk page. (May 2012) | Environmental Change and Human Health, a special section of World Resources 1998-99 in this report describes how preventable illnesses and premature deaths are still occurring in very large numbers. If vast improvements are made in human health, millions of people will be living longer, healthier lives than ever before.

In these poorest regions of the world an estimated 11 million children, or about one in five, will not live to see their fifth birthday, primarily because of environment-related diseases. Child mortality is larger than the combined populations of Norway and Switzerland, and mostly due to malaria, acute respiratory infections or diarrhea — illnesses that are largely preventable.

Water management * 2 See also * 3 References * 4 External links| [edit] Water deterioration One major component of environmental degradation is the depletion of the resource of fresh water on Earth. Approximately only 2. 5% of all of the water on Earth is fresh water, with the rest being salt water. 69% of the fresh water is frozen in ice caps located on Antarctica and Greenland, so only 30% of the 2. 5% of fresh water is available for consumption. [3] Fresh water is an exceptionally important resource, since life on Earth is ultimately dependent on it.

Water transports nutrients and chemicals within the biosphere to all forms of life, sustains both plants and animals, and molds the surface of the Earth with transportation and deposition of materials. [4] The current top three uses of fresh water account for 95% of its consumption; approximately 85% is used for irrigation of farmland, golf courses, and parks, 6% is used for domestic purposes such as indoor bathing uses and outdoor garden and lawn use, and 4% is used for industrial purposes such as processing, washing, and cooling in manufacturing centers. 5] It is estimated that one in three people over the entire globe are already facing water shortages, almost one-fifth of the world’s population live in areas of physical water scarcity, and almost one quarter of the world’s population live in a developing country that lacks the necessary infrastructure to use water from available rivers and aquifers.

Water scarcity is an increasing problem due to many foreseen issues in the future, including population growth, increased urbanization, higher standards of living, and climate change. 3] [edit] Climate change and temperature Climate change affects the Earth’s water supply in a large number of ways. It is predicted that the mean global temperature will rise in the coming years due to a number of forces affecting the climate, the amount of atmospheric CO2 will rise, and both of these will influence water resources; evaporation depends strongly on temperature and moisture availability, which can ultimately affect the amount of water available to replenish groundwater supplies.

Transpiration from plants can be affected by a rise in atmospheric CO2, which can decrease their use of water, but can also raise their use of water from possible increases of leaf area. Temperature increase can decrease the length of the snow season in the winter and increase the intensity of snowmelt in warmer seasons, leading to peak runoff of snowmelt earlier in the season, affecting soil moisture, flood and drought risks, and storage capacities depending on the area. [6] Warmer winter temperatures cause a decrease in snowpack, which can result in diminished water resources during the summer.

This is especially important at mid-latitudes and in mountain regions that depend on glacial runoff to replenish their river systems and groundwater supplies, making these areas increasingly vulnerable to water shortages over time; an increase in temperature will initially result in a rapid rise in water melting from glaciers in the summer, followed by a retreat in glaciers and a decrease in the melt and consequently the water supply every year as the size of these glaciers get smaller and smaller. 3]

Thermal expansion of water and increased melting of oceanic glaciers from an increase in temperature gives way to a rise in sea level, which can affect the fresh water supply of coastal areas as well; as river mouths and deltas with higher salinity get pushed further inland, an intrusion of saltwater results in an increase of salinity in reservoirs and aquifers. 5] Sea-level rise may also consequently be caused by a depletion of groundwater,[7] as climate change can affect the hydrologic cycle in a number of ways. Uneven distributions of increased temperatures and increased precipitation around the globe results in water surpluses and deficits,[6] but a global decrease in groundwater suggests a rise in sea level, even after meltwater and thermal expansion were accounted for,[7] which can provide a positive feedback to the problems sea-level rise causes to fresh-water supply.

A rise in air temperature results in a rise in water temperature, which is also very significant in water degradation, as the water would become more susceptible to bacterial growth. An increase in water temperature can also affect ecosystems greatly because of a species’ sensitivity to temperature, and also by inducing changes in a body of water’s self-purification system from decreased amounts of dissolved oxygen in the water due to rises in temperature. [3] [edit] Climate change and precipitation

A rise in global temperatures is also predicted to correlate with an increase in global precipitation, but because of increased runoff, floods, increased rates of soil erosion, and mass movement of land, a decline in water quality is probable, while water will carry more nutrients, it will also carry more contaminants. [3] While most of the attention about climate change is directed towards global warming and greenhouse effect, some of the most severe effects of climate change are likely to be from changes in precipitation, evapotranspiration, runoff, and soil moisture.

It is generally expected that, on average, global precipitation will increase, with some areas receiving increases and some decreases. Climate models show that while some regions should expect an increase in precipitation,[6] such as in the tropics and higher latitudes, other areas are expected to see a decrease, such as in the subtropics; this will ultimately cause a latitudinal variation in water distribution. 3] The areas receiving more precipitation are also expected to receive this increase during their winter and actually become drier during their summer,[6] creating even more of a variation of precipitation distribution. Naturally, the distribution of precipitation across the planet is very uneven, causing constant variations in water availability in respective locations. Changes in precipitation affect the timing and magnitude of floods and droughts, shift runoff processes, and alter groundwater recharge rates.

Vegetation patterns and growth rates will be directly affected by shifts in precipitation amount and distribution, which will in turn affect agriculture as well as natural ecosystems. Decreased precipitation will deprive areas of water, causing water tables to fall and reservoirs and wetlands, rivers, and lakes to empty,[6] and possibly an increase in evaporation and evapotranspiration, depending on the accompanied rise in temperature. [5] Groundwater reserves will be depleted, and the remaining water has a greater chance of being of poor quality from saline or contaminants on the land surface. 3] [edit] Population growth The available fresh water being affected by climate is also being stretched across an ever-increasing global population. It is estimated that almost a quarter of the global population is living in an area that is using more than 20% of their renewable water supply; water use will rise with population while the water is also being aggravated by decreases in streamflow and groundwater caused by climate change.

Even though some areas may see an increase in freshwater supply from an uneven distribution of precipitation increase, an increased use of water supply is expected. [8] An increased population means increased withdrawals from the water supply for domestic, agricultural, and industrial uses, the largest of these being agriculture,[9] believed to be the major non-climate driver of environmental change and water deterioration.

The next 50 years will likely be the last period of rapid agricultural expansion, but the larger and wealthier population over this time will demand more agriculture. [10] Population increase over the last two decades, at least in the United States, has also been accompanied by a shift to an increase in urban areas from rural areas,[11] which concentrates the demand for water into certain areas, and puts stress on the fresh water supply from industrial and human contaminants. 3] Urbanization causes overcrowding and increasingly unsanitary living conditions, especially in developing countries, which in turn exposes an increasingly number of people to disease. About 79% of the world’s population is in developing countries, which lack access to sanitary water and sewer systems, giving rises to disease and deaths from contaminated water and increased numbers of disease-carrying insects. [12] [edit] Agriculture

Agriculture is dependent on available soil moisture, which is directly affected by climate dynamics, with precipitation being the input in this system and various processes being the output, such as evapotranspiration, surface runoff, drainage, and percolation into groundwater. Changes in climate, especially the changes in precipitation and evapotranspiration predicted by climate models, will directly affect soil moisture, surface runoff, and groundwater recharge. In areas with decreasing precipitation as predicted by the climate models, soil moisture may be substantially educed. [6] With this in mind, agriculture in most areas needs irrigation already, which depletes fresh water supplies both by the physical use of the water and the degradation agriculture causes to the water. Irrigation increases salt and nutrient content in areas that wouldn’t normally be affected, and damages streams and rivers from damming and removal of water. Fertilizer enters both human and livestock waste streams that eventually enter groundwater, while nitrogen, phosphorus, and other chemicals from fertilizer can acidify both soils and water.

Certain agricultural demands may increase more than others with an increasingly wealthier global population, and meat is one commodity expected to double global food demand by 2050,[10] which directly affects the global supply of fresh water. Cows need water to drink, more if the temperature is high and humidity is low, and more if the production system the cow is in is extensive, since finding food takes more effort. Water is needed in processing of the meat, and also in the production of feed for the livestock.

Manure can contaminate bodies of freshwater, and slaughterhouses, depending on how well they are managed, contribute waste such as blood, fat, hair, and other bodily contents to supplies of fresh water. [13] The transfer of water from agricultural to urban and suburban use raises concerns about agricultural sustainability, rural socioeconomic decline, food security, an increased carbon footprint from imported food, and decreased foreign trade balance. 9] The depletion of fresh water, as applied to more specific and populated areas, increases fresh water scarcity among the population and also makes populations susceptible to economic, social, and political conflict in a number of ways; rising sea levels forces migration from coastal areas to other areas farther inland, pushing populations closer together breaching borders and other geographical patterns, and agricultural surpluses and deficits from the availability of water induce trade problems and economies of certain areas. 8]

CLimate change is an important cause of involuntary migration and forced displacement[14] [edit] Water management The issue of the depletion of fresh water can be met by increased efforts in water management. [4] While water management systems are often flexible, adaptation to new hydrologic conditions may be very costly. [6] Preventative approaches are necessary to avoid high costs of inefficiency and the need for rehabilitation of water supplies,[4] and innovations to decrease overall demand may be important in planning water sustainability. 9] Water supply systems, as they exist now, were based on the assumptions of the current climate, and built to accommodate existing river flows and flood frequencies. Reservoirs are operated based on past hydrologic records, and irrigation systems on historical temperature, water availability, and crop water requirements; these may not be a reliable guide to the future. Re-examining engineering designs, operations, optimizations, and planning, as well as re-evaluating legal, technical, and economic approaches to manage water resources are very important for the future of water management in response to water degradation.

Another approach is water privatization; despite its economic and cultural effects, service quality and overall quality of the water can be more easily controlled and distributed. Rationality and sustainability is appropriate, and requires limits to overexploitation and pollution, and efforts in conservation.

Natural hazards are excluded as a cause, however human activities can indirectly affect phenomena such as floods and bush fires. 8. This is considered to be an important topic of the 21st century due to the implications land degradation has upon agronomic productivity, the environment, and its effects on food security. 3] It is estimated that up to 40% of the world’s agricultural land is seriously degrad Measuring Land degradation is a broad term that can be applied differently across a wide range of scenarios. There are four main ways of looking at land degradation and its impact on the environment around it: * A temporary or permanent decline in the productive capacity of the land.

This can be seen through a loss of biomass, a loss of actual productivity or in potential productivity, or a loss or change in vegetative cover and soil nutrients. A decline in the lands “usefulness”: A loss or reduction in the lands capacity to provide resources for human livelihoods. This can be measured from a base line of past land use. * Loss of biodiversity: A loss of range of species or ecosystem complexity as a decline in the environmental quality. * Shifting ecological risk: increased vulnerability of the environment or people to destruction or crisis. This is measured through a base line in the form of pre-existing risk of crisis or destruction. A problem with measuring land degradation is that what one group of people call degradation, others might view as a benefit or opportunity.

For example, heavy rainfall could make a scientific group be worried about high erosion of the soil while farmers could view it as a good opportunity to plant crops. [5] [edit] Causes Overgrazing by livestock can lead to land degradation Land degradation is a global problem, largely related to agricultural use. The major causes include:[citation needed] * Land clearance, such as clearcutting and deforestation * Agricultural depletion of soil nutrients through poor farming practices * Livestock including overgrazing and overdrafting * Inappropriate irrigation[6] and overdrafting * Urban sprawl and commercial development Soil contamination including * Vehicle off-roading * Quarrying of stone, sand, ore and minerals * Increase in field size due to economies of scale, reducing shelter for wildlife, as hedgerows and copses disappear * Exposure of naked soil after harvesting by heavy equipment * Monoculture, destabilizing the local ecosystem * Dumping of non-biodegradable trash, such as plastics [edit] Effects Soil erosion in a wheat field near Pullman, USA. The main outcome of land degradation is a substantial reduction in the productivity of the land.

[7] The major stresses on vulnerable land include: * Accelerated soil erosion by wind and water Soil acidification and the formation of acid sulfate soil resulting in barren soil * Soil alkalinisation owing to irrigation with water containing sodium bicarbonate leading to poor soil structure and reduced crop yields * Soil salination in irrigated land requiring soil salinity control to reclaim the land [8] * Soil waterlogging in irrigated land which calls for some form of subsurface land drainage to remediate the negative effects [8] * Destruction of soil structure including loss of organic matter Overcutting of vegetation occurs when people cut forests, woodlands and shrublands—to obtain timber, fuelwood and other products—at a pace exceeding the rate of natural regrowth. This is frequent in semi-arid environments, where fuelwood shortages are often severe. Overgrazing is the grazing of natural pastures at stocking intensities above the livestock carrying capacity; the resulting decrease in the vegetation cover is a leading cause of wind and water erosion. It is a significant factor in Afghanistan.

Agricultural activities that can cause land degradation include shifting cultivation without adequate fallow periods, absence of soil conservation measures, fertilizer use, and a host of possible problems arising from faulty planning or management of irrigation. They are a major factor in Sri Lanka and the dominant one in Bangladesh. The role of population factors in land degradation processes obviously occurs in the context of the underlying causes. In the region, in fact, it is indeed one of the two along with land shortage, and land shortage itself ultimately is a consequence of continued population growth in the face of the finiteness of land resources. In the context of land shortage the growing population pressure, during 1980-1990, has led to decreases in the already small areas of agricultural land per person in six out of eight countries (14% for India and 22% for Pakistan).

Population pressure also operates through other mechanisms. Improper agricultural practices, for instance, occur only under constraints such as the saturation of good lands under population pressure which leads settlers to cultivate too shallow or too steep soils, plough fallow land before it has recovered its fertility, or attempt to obtain multiple crops by irrigating unsuitable soils. High population density is not always related to land degradation. Rather, it is the practices of the human population that can cause a landscape to become degraded. Populations can be a benefit to the land and make it more productive than it is in its natural state.

Land degradation is important factor of internal displacement in many African and Asian countries[9] Severe land degradation affects a significant portion of the Earth’s arable lands, decreasing the wealth and economic development of nations. As the land resource base becomes less productive, food security is compromised and competition for dwindling resources increases, the seeds of famine and potential conflict are sewn. [edit] Sensitivity and resilience Sensitivity and resilience are measures of the vulnerability of a landscape to degradation. These two factors combine to explain the degree of vulnerability. [5] Sensitivity is the degree to which a land system undergoes change due to natural forces, human intervention or a combination of both.

Resilience is the ability of a landscape to absorb change, without significantly altering the relationship between the relative importance and numbers of individuals and species that compose the community. [10] It also refers to the ability of the region to return to its original state after being changed in some way. The resilience of a landscape can be increased or decreased through human interaction based upon different methods of land-use management. Land that is degraded becomes less resilient than undegraded land, which can lead to even further degration through shocks to the landscape. [edit] Climate change Significant land degradation from seawater inundation, particularly in river deltas and on low-lying islands, is a potential hazard that was identified in a 2007 IPCC report. citation needed] As a result of sea-level rise from climate change, salinity levels can reach levels where agriculture becomes impossible in very low lying areas.

Journal ofLand Degradation & DevelopmentVol 24 (6 Issues in 2013)Edited by: Professor Artemi CerdàPrint ISSN: 1085-3278 Online ISSN: 1099-145X| * Description Land Degradation & Development is an international journal which seeks to promote rational study of the recognition, monitoring, control and rehabilitation of degradation in terrestrial environments. The journal focuses on: * what land degradation is; * what causes land degradation; * the impacts of land degradation * the scale of land degradation; * the history, current status or future trends of land degradation; * avoidance, mitigation and control of land degradation; * remedial actions to rehabilitate or restore degraded land; * sustainable land management.

Land degradation may be defined as the loss of utility or potential utility through the reduction of or damage to physical, social, cultural or economic features, and/or reduction of ecosystem diversity. There may be a single cause or a complex mix of causes, some may be biogeophysical (‘natural’), some socioeconomic (‘human’) and it is quite possible that cause(s) will be indirect, perhaps cumulative and difficult to identify. A major challenge is to learn how interactions between development and environment can be better managed to increase prospects for ecologically and socially sustainable improvements to human well-being.

Development means attempts to improve human well-being or environmental quality in rich and poor nations on a sustained basis (sustainable development). Papers are invited on scientific, social, economic, political and historical aspects of terrestrial environmental degradation. Also welcome are analyses presenting forecasts of trends, case studies and discussion on management, planning and policy-making relating to the promotion of ecological sustainability and the counteraction of land degradation.

Water pollution From Wikipedia, the free encyclopedia Jump to: navigation, search Raw sewage and industrial waste in the New River as it passes from Mexicali to Calexico, California. Water pollution is the contamination of water bodies (e. g. lakes, rivers, oceans, aquifers and groundwater).

Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities. * 1 Introduction * 2 Categories * 2. 1 Point sources * 2. 2 Nonpoint sources * 3 Groundwater pollution * 4 Causes * 4. 1 Pathogens * 4. 2 Chemical and other contaminants * 4. 3 Thermal pollution * 5 Transport and chemical reactions of water pollutants * 6 Measurement * 6. 1 Sampling * 6. 2 Physical testing * 6.

It has been suggested that it is the leading worldwide cause of deaths and diseases,[1][2] and that it accounts for the deaths of more than 14,000 people daily. 2] An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrheal sickness every day. [3] Some 90% of China’s cities suffer from some degree of water pollution,[4] and nearly 500 million people lack access to safe drinking water. [5] In addition to the acute problems of water pollution in developing countries, developed countries continue to struggle with pollution problems as well. In the most recent national report on water quality in the United States, 45 percent of assessed stream miles, 47 percent of assessed lake acres, and 32 percent of assessed bays and estuarine square miles were classified as polluted. 6]

Water is typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use, such as drinking water, and/or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. Natural phenomena such as volcanoes, algae blooms, storms, and earthquakes also cause major changes in water quality and the ecological status of water. Categories Surface water and groundwater have often been studied and managed as separate resources, although they are interrelated. [7] Surface water seeps through the soil and becomes groundwater. Conversely, groundwater can also feed surface water sources. Sources of surface water pollution are generally grouped into two categories based on their origin. Point sources

Point source pollution – Shipyard – Rio de Janeiro. Point source water pollution refers to contaminants that enter a waterway from a single, identifiable source, such as a pipe or ditch. Examples of sources in this category include discharges from a sewage treatment plant, a factory, or a city storm drain. The U. S. Clean Water Act (CWA) defines point source for regulatory enforcement purposes. [8] The CWA definition of point source was amended in 1987 to include municipal storm sewer systems, as well as industrial stormwater, such as from construction sites. [9] Nonpoint sources Nonpoint source pollution refers to diffuse contamination that does not originate from a single discrete source.

NPS pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. A common example is the leaching out of nitrogen compounds from fertilized agricultural lands. Nutrient runoff in stormwater from “sheet flow” over an agricultural field or a forest are also cited as examples of NPS pollution. Contaminated storm water washed off of parking lots, roads and highways, called urban runoff, is sometimes included under the category of NPS pollution. However, this runoff is typically channeled into storm drain systems and discharged through pipes to local surface waters, and is a point source. Groundwater pollution See also: Hydrogeology Interactions between groundwater and surface water are complex.

Consequently, groundwater pollution, sometimes referred to as groundwater contamination, is not as easily classified as surface water pollution. [7] By its very nature, groundwater aquifers are susceptible to contamination from sources that may not directly affect surface water bodies, and the distinction of point vs. non-point source may be irrelevant. A spill or ongoing releases of chemical or radionuclide contaminants into soil (located away from a surface water body) may not create point source or non-point source pollution, but can contaminate the aquifer below, defined as a toxin plume. The movement of the plume, called a plume front, may be analyzed through a hydrological transport model or groundwater model.

Analysis of groundwater contamination may focus on the soil characteristics and site geology, hydrogeology, hydrology, and the nature of the contaminants. Causes The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc. ) the concentration is often the key in determining what is a natural component of water, and what is a contaminant. High concentrations of naturally occurring substances can have negative impacts on aquatic flora and fauna.

Oxygen-depleting substances may be natural materials, such as plant matter (e. g. leaves and grass) as well as man-made chemicals. Other natural and anthropogenic substances may cause turbidity (cloudiness) which blocks light and disrupts plant growth, and clogs the gills of some fish species. [10] Many of the chemical substances are toxic. Pathogens can produce waterborne diseases in either human or animal hosts. [11] Alteration of water’s physical chemistry includes acidity (change in pH), electrical conductivity, temperature, and eutrophication. Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases in the primary productivity of the ecosystem.

Depending on the degree of eutrophication, subsequent negative environmental effects such as anoxia (oxygen depletion) and severe reductions in water quality may occur, affecting fish and other animal populations. Pathogens A manhole cover unable to contain a sanitary sewer overflow. Coliform bacteria are a commonly used bacterial indicator of water pollution, although not an actual cause of disease. Other microorganisms sometimes found in surface waters which have caused human health problems include: * Burkholderia pseudomallei * Cryptosporidium parvum * Giardia lamblia * Salmonella * Novovirus and other viruses * Parasitic worms (helminths). [12][13] High levels of pathogens may result from inadequately treated sewage discharges. 14]

This can be caused by a sewage plant designed with less than secondary treatment (more typical in less-developed countries). In developed countries, older cities with aging infrastructure may have leaky sewage collection systems (pipes, pumps, valves), which can cause sanitary sewer overflows. Some cities also have combined sewers, which may discharge untreated sewage during rain storms. [15] Pathogen discharges may also be caused by poorly managed livestock operations. Chemical and other contaminants Muddy river polluted by sediment. Photo courtesy of United States Geological Survey. Contaminants may include organic and inorganic substances. Organic water pollutants include:

* Detergents Disinfection by-products found in chemically disinfected drinking water, such as chloroform * Food processing waste, which can include oxygen-demanding substances, fats and grease * Insecticides and herbicides, a huge range of organohalides and other chemical compounds * Petroleum hydrocarbons, including fuels (gasoline, diesel fuel, jet fuels, and fuel oil) and lubricants (motor oil), and fuel combustion byproducts, from stormwater runoff[16] * Tree and bush debris from logging operations * Volatile organic compounds (VOCs), such as industrial solvents, from improper storage. * Chlorinated solvents, which are dense non-aqueous phase liquids (DNAPLs), may fall to the bottom of reservoirs, since they don’t mix well with water and are denser. * Polychlorinated biphenyl (PCBs) * Trichloroethylene * Perchlorate * Various chemical compounds found in personal hygiene and cosmetic products.

A garbage collection boom in an urban-area stream in Auckland, New Zealand. Inorganic water pollutants include: * Acidity caused by industrial discharges (especially sulfur dioxide from power plants) * Ammonia from food processing waste * Chemical waste as industrial by-products * Fertilizers containing nutrients–nitrates and phosphates—which are found in stormwater runoff from agriculture, as well as commercial and residential use[16] * Heavy metals from motor vehicles (via urban stormwater runoff)[16][17] and acid mine drainage * Silt (sediment) in runoff from construction sites, logging, slash and burn practices or land clearing sites. Macroscopic Pollution in Parks Milwaukee, WI

Macroscopic pollution—large visible items polluting the water—may be termed “floatables” in an urban stormwater context, or marine debris when found on the open seas, and can include such items as: * Trash or garbage (e. g. paper, plastic, or food waste) discarded by people on the ground, along with accidental or intentional dumping of rubbish, that are washed by rainfall into storm drains and eventually discharged into surface waters * Nurdles, small ubiquitous waterborne plastic pellets * Shipwrecks, large derelict ships. Thermal pollution Main article: Thermal pollution Thermal pollution is the rise or fall in the temperature of a natural body of water caused by human influence.

Thermal pollution, unlike chemical pollution, results in a change in the physical properties of water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. Elevated water temperatures decreases oxygen levels (which can kill fish) and affects ecosystem composition, such as invasion by new thermophilic species. Urban runoff may also elevate temperature in surface waters. Thermal pollution can also be caused by the release of very cold water from the base of reservoirs into warmer rivers. Transport and chemical reactions of water pollutants See also: Marine pollution Most water pollutants are eventually carried by rivers into the oceans.

In some areas of the world the influence can be traced hundred miles from the mouth by studies using hydrology transport models. Advanced computer models such as SWMM or the DSSAM Model have been used in many locations worldwide to examine the fate of pollutants in aquatic systems. Indicator filter feeding species such as copepods have also been used to study pollutant fates in the New York Bight, for example. The highest toxin loads are not directly at the mouth of the Hudson River, but 100 kilometers south, since several days are required for incorporation into planktonic tissue. The Hudson discharge flows south along the coast due to coriolis force.

Further south then are areas of oxygen depletion, caused by chemicals using up oxygen and by algae blooms, caused by excess nutrients from algal cell death and decomposition. Fish and shellfish kills have been reported, because toxins climb the food chain after small fish consume copepods, then large fish eat smaller fish, etc. Each successive step up the food chain causes a stepwise concentration of pollutants such as heavy metals (e. g. mercury) and persistent organic pollutants such as DDT. This is known as biomagnification, which is occasionally used interchangeably with bioaccumulation. A polluted river draining an abandoned copper mine on Anglesey Large gyres (vortexes) in the oceans trap floating plastic debris.

The North Pacific Gyre for example has collected the so-called “Great Pacific Garbage Patch” that is now estimated at 100 times the size of Texas. Many of these long-lasting pieces wind up in the stomachs of marine birds and animals. This results in obstruction of digestive pathways which leads to reduced appetite or even starvation. Many chemicals undergo reactive decay or chemically change especially over long periods of time in groundwater reservoirs. A noteworthy class of such chemicals is the chlorinated hydrocarbons such as trichloroethylene (used in industrial metal degreasing and electronics manufacturing) and tetrachloroethylene used in the dry cleaning industry (note latest advances in liquid carbon dioxide in dry cleaning that avoids all use of chemicals).

Both of these chemicals, which are carcinogens themselves, undergo partial decomposition reactions, leading to new hazardous chemicals (including dichloroethylene and vinyl chloride). Groundwater pollution is much more difficult to abate than surface pollution because groundwater can move great distances through unseen aquifers. Non-porous aquifers such as clays partially purify water of bacteria by simple filtration (adsorption and absorption), dilution, and, in some cases, chemical reactions and biological activity: however, in some cases, the pollutants merely transform to soil contaminants. Groundwater that moves through cracks and caverns is not filtered and can be transported as easily as surface water.

In fact, this can be aggravated by the human tendency to use natural sinkholes as dumps in areas of Karst topography. There are a variety of secondary effects stemming not from the original pollutant, but a derivative condition. An example is silt-bearing surface runoff, which can inhibit the penetration of sunlight through the water column, hampering photosynthesis in aquatic plants. Water pollution may be analyzed through several broad categories of methods: physical, chemical and biological. Most involve collection of samples, followed by specialized analytical tests. Some methods may be conducted in situ, without sampling, such as temperature.

Government agencies and research organizations have published standardized, validated analytical test methods to facilitate the comparability of results from disparate testing events. [18] Sampling Sampling of water for physical or chemical testing can be done by several methods, depending on the accuracy needed and the characteristics of the contaminant. Many contamination events are sharply restricted in time, most commonly in association with rain events. For this reason “grab” samples are often inadequate for fully quantifying contaminant levels. Scientists gathering this type of data often employ auto-sampler devices that pump increments of water at either time or discharge intervals.

Sampling for biological testing involves collection of plants and/or animals from the surface water body. Depending on the type of assessment, the organisms may be identified for biosurveys (population counts) and returned to the water body, or they may be dissected for bioassays to determine toxicity. Further information: Water quality#Sampling and Measurement Physical testing Common physical tests of water include temperature, solids concentrations (e. g. , total suspended solids (TSS)) and turbidity. Chemical testing See also: water chemistry analysis and environmental chemistry Water samples may be examined using the principles of analytical chemistry. Many published test methods are available for both organic and inorganic compounds.

Frequently used methods include pH, biochemical oxygen demand (BOD),[19]:102 chemical oxygen demand (COD),[19]:104 nutrients (nitrate and phosphorus compounds), metals (including copper, zinc, cadmium, lead and mercury), oil and grease, total petroleum hydrocarbons (TPH), and pesticides. Biological testing Main article: Bioindicator Biological testing involves the use of plant, animal, and/or microbial indicators to monitor the health of an aquatic ecosystem. Control of pollution Domestic sewage Main article: Sewage treatment Deer Island Waste Water Treatment Plant serving Boston, Massachusetts and vicinity. Domestic sewage is 99. 9 percent pure water, while the other 0. 1 percent are pollutants.

Although found in low concentrations, these pollutants pose risk on a large scale. [20] In urban areas, domestic sewage is typically treated by centralized sewage treatment plants. In the U. S. , most of these plants are operated by local government agencies, frequently referred to as publicly owned treatment works (POTW). Municipal treatment plants are designed to control conventional pollutants: BOD and suspended solids. Well-designed and operated systems (i. e. , secondary treatment or better) can remove 90 percent or more of these pollutants. Some plants have additional sub-systems to treat nutrients and pathogens. Most municipal plants are not designed to treat toxic pollutants found in industrial wastewater. 21]

Cities with sanitary sewer overflows or combined sewer overflows employ one or more engineering approaches to reduce discharges of untreated sewage, including: * utilizing a green infrastructure approach to improve stormwater management capacity throughout the system, and reduce the hydraulic overloading of the treatment plant[22] * repair and replacement of leaking and malfunctioning equipment[15] * increasing overall hydraulic capacity of the sewage collection system (often a very expensive option). A household or business not served by a municipal treatment plant may have an individual septic tank, which treats the wastewater on site and discharges into the soil.

Alternatively, domestic wastewater may be sent to a nearby privately owned treatment system (e. g. in a rural community). Some industrial facilities generate ordinary domestic sewage that can be treated by municipal facilities. Industries that generate wastewater with high concentrations of conventional pollutants (e. g. oil and grease), toxic pollutants (e. g. heavy metals, volatile organic compounds) or other nonconventional pollutants such as ammonia, need specialized treatment systems. Some of these facilities can install a pre-treatment system to remove the toxic components, and then send the partially treated wastewater to the municipal system.

Industries generating large volumes of wastewater typically operate their own complete on-site treatment systems. Some industries have been successful at redesigning their manufacturing processes to reduce or eliminate pollutants, through a process called pollution prevention. Heated water generated by power plants or manufacturing plants may be controlled with: * cooling ponds, man-made bodies of water designed for cooling by evaporation, convection, and radiation * cooling towers, which transfer waste heat to the atmosphere through evaporation and/or heat transfer * cogeneration, a process where waste heat is recycled for domestic and/or industrial heating purposes. [23] Agricultural wastewater

Main article: Agricultural wastewater treatment Riparian buffer lining a creek in Iowa Nonpoint source controls Sediment (loose soil) washed off fields is the largest source of agricultural pollution in the United States. [10] Farmers may utilize erosion controls to reduce runoff flows and retain soil on their fields. Common techniques include contour plowing, crop mulching, crop rotation, planting perennial crops and installing riparian buffers. [24][25]:pp. 4-95–4-96 Nutrients (nitrogen and phosphorus) are typically applied to farmland as commercial fertilizer; animal manure; or spraying of municipal or industrial wastewater (effluent) or sludge.

Nutrients may also enter runoff from crop residues, irrigation water, wildlife, and atmospheric deposition. [25]:p. 2-9 Farmers can develop and implement nutrient management plans to reduce excess application of nutrients. [24][25]:pp. 4-37–4-38 To minimize pesticide impacts, farmers may use Integrated Pest Management (IPM) techniques (which can include biological pest control) to maintain control over pests, reduce reliance on chemical pesticides, and protect water quality. [26] Feedlot in the United States Point source wastewater treatment Farms with large livestock and poultry operations, such as factory farms, are called concentrated animal feeding operations or feedlots in the US and are being subject to increasing government regulation. 27][28] Animal slurries are usually treated by containment in anaerobic lagoons before disposal by spray or trickle application to grassland.

Constructed wetlands are sometimes used to facilitate treatment of animal wastes. Some animal slurries are treated by mixing with straw and composted at high temperature to produce a bacteriologically sterile and friable manure for soil improvement. Construction site stormwater Silt fence installed on a construction site. Sediment from construction sites is managed by installation of: * erosion controls, such as mulching and hydroseeding, and * sediment controls, such as sediment basins and silt fences. [29] Discharge of toxic chemicals such as motor fuels and concrete washout is prevented by use of: * spill prevention and control plans, and specially designed containers (e. g. for concrete washout) and structures such as overflow controls and diversion berms. [30] Urban runoff (stormwater) Main article: Urban runoff See also: Green infrastructure Retention basin for controlling urban runoff Effective control of urban runoff involves reducing the velocity and flow of stormwater, as well as reducing pollutant discharges. Local governments use a variety of stormwater management techniques to reduce the effects of urban runoff.

These techniques, called best management practices (BMPs) in the U. S. , may focus on water quantity control, while others focus on improving water quality, and some perform both functions. 31] Pollution prevention practices include low-impact development techniques, installation of green roofs and improved chemical handling (e. g. management of motor fuels & oil, fertilizers and pesticides). [32] Runoff mitigation systems include infiltration basins, bioretention systems, constructed wetlands, retention basins and similar devices. [33][34] Thermal pollution from runoff can be controlled by stormwater management facilities that absorb the runoff or direct it into groundwater, such as bioretention systems and infiltration basins. Retention basins tend to be less effective at reducing temperature, as the water may be heated by the sun before being discharged to a receiving stream. [31]:p. 5-58 *

There are three external factors that affect business: Political, Legal and Social. Political factors involve political stability, government support, taxation and direct support. Legal factor involves things such as employment laws, consumer laws, it also influence attitudes such as healthy eating. Social factor involves education, age, ethics, attitudes etc. Political factors An activity related to government policy and its administrative practices that can have an effect on something.

Most business operators will keep a watchful eye on any political factor, such as new legislation or regulatory shifts, which could have a substantial impact on how their company operates and its bottom line. Political decisions involve making choices that affect large number of people and business. Government support for different types of organization- government supports different organizations in different ways. There are three types of organizations- private, public and nonprofit/voluntary.

In private sector, government tries to create an environment where business can compete. In the nonprofit/voluntary sector, government support business by giving various grants and tax reliefs. In the public sector the government covers the losses made by government owned organizations. Governments use taxation to encourage or discourage certain economic decisions. For example, reduction in taxable personal (or household) income by the amount paid as interest on home mortgage loans results in greater construction activity, and generates more jobs.

Government also puts high taxes, for example they put high taxes on cigarettes and alcohol to discourage smoking and drinking, and high taxes on fuel to reduce pollution by discouraging people of driving cars so much. Government also tries enhancing the skills of the population. They enhance education and training help to increase skills of working population. They provide a range of training and creates the educational framework including different types of qualifications, such as Apprenticeships and NVQs. Legal factors Business must operate within the framework of the law.

There are three laws that affect business: Company law- how business set up and run, Contract law- contracts that business make with suppliers, employees and etc, and Competition law- how business are allowed to compare with each other. The Contract Law is a set of rules governing the relationship, content and validity of an agreement between two or more persons regarding the sale of goods, provision of services or exchange of interests or ownership. The reason for this is due to the big number of examples in which contracts can arise in everyday life.

Contract law is law that governs oral and written agreements associated with exchange of goods and services, money, and properties. It includes consumer protection and employment law. Consumer protection involves: •Sales of Goods Act, this act means that the retailers have to sell goods as they are described and satisfactory quality. It means that marketing should describe the product accurately. These laws are aimed at safeguarding consumers by ensuring that goods offered for sale are reasonably safe, and meet certain standards of quality to make them fit for their intended use. The consumer credit act this applies to business who sells goods on credit, or companies that lend money. Business need to be licensed by the Office of Fair Trading. This act wants business to give their customers updates on their account regularly. If the customer falls behind the repayments the FOS may extend the time for the customer to repay their debt. •Employment law means that employees are also protected at work. The contract of employment should include names of both parties, job title and description, hours of work, wages etc. Social factors

Are factors that influence individuals’ personality, attitudes and lifestyle. Demographic issues, when a population of a country is growing, there is an increase in goods and services and people available to work. Changes in structure means aging population. When the number of older people increase fast the demand for some goods increase, for example wheel chairs, anti-aging creams, world cruises etc. Household and families, there are increasing number of single-person households in the uk. The average marriage age is increasing aswell and many people now live alone.

Education- the level of education is very important nowadays. In almost all industries employers are expecting employees to have a good information about technology, and have good skills at the job they’re doing. Attitudes to work influence relationships between employers and employees. Britain has developed a long working hour’s culture compared to France and Italy. How external factors affect McDonalds in the UK and Lithuania McDonald’s is the world largest chain of fast food restaurants with more than 30000 restaurants serving 52 million customers in more than 100 countries each day.

McDonald’s primarily sells hamburgers, cheeseburgers, chicken products, french-fries, breakfast items, soft drinks, milkshakes and desserts. More recently, it has begun to offer salads, wraps and fruit. Each McDonald’s restaurant is operated by franchise, an affiliate, or the corporation itself. The corporation revenues come from the rent, royalties and fees paid by the franchisees, as well as sales in company-operated restaurants. McDonald’s revenues grew 27% over the three years ending in 2007 to $22. 8 billion, and 9% growth in operating income to $ 3. billion. Within the UK there are approximately 1200 restaurants employing over 85,000 people. In Lithuania there are just 9 restaurants employing less than 200 people. Political factors In the UK McDonald’s main competitors are Chippy Shops, Subway and KFC. McDonalds always needed to treat competitors carefully. That’s way the factor related with competitor like competitors product quality, service, price competition, market, sales, growth everything impacting McDonalds. In Lithuania the only competitor for McDonalds is Hesburger.

There are not many fast food restaurants so there is not much competition going on. In both countries employees are impacting McDonalds because company is recruiting, training staff for company. It is not uncommon for McDonalds to be the employer of first resort for young people just entering the workforce, older workers desiring extra income, or for those planning on transferring from one corporation to another. So, employee is impacting McDonalds in this way. Legal factors In both counties McDonalds producing their product and they are serving those directly to customers.

That’s way the factor of product and service is impacting McDonalds. Product quality, product variety, quick and friendly service, every things are important for company. Those got an important impact on McDonalds. Employment law also affects McDonalds in the UK and Lithuania. In the UK minim wage is: Apprentice- ? 2. 65, under 18- ? 3. 68, 18 to 20- ? 4. 98 , and over 21- ? 6. 19. In Lithuania, there are not hourly wages, but the minimum salary for everyone in Lithuania is 232 euro a month.

People in England has more money to spend on fast food restaurants than Lithuanians due to a larger income, therefore McDonald restaurants make much bigger profits in the UK than in Lithuania. Social factors In the UK there are many more McDonald’s restaurants than in Lithuania, mainly because of people’s Lithuanian people are more keen on healthy eating than British people. Most of Lithuanian people grow their own vegetables and fruit; they also like to buy organic foods from the market, and stays away from fast food restaurants. McDonalds are not so popular in Lithuania as it is in the UK because of different coulture.

1.  Explain the role of the Internet in providing the technical environment for businesses who manufacture new technologies and the advantages of it. Support your answers with real examples (at least three examples).

The modern world of technological advancement is associated with a number of improvements especially in business transactions. The use of information and communication technology as a tool of doing business incorporates the purpose of internet. A major advancement in technological advancement is the internet which has led to integration of business transactions across regions. Internet plays a very important role in creating technical environment for organizations that manufacture new technologies (Andrea, Andrew, Michael, 2003). The global interconnection of computer network through a protocol known as internet has an integrating force. The internet connects communication technology and computing to provide information necessary for business.

Key roles of internet include research, sale of products and communication of a company’s message to consumers. Businesses that manufacture new technologies conduct research via internet to acquire relevant information about their services. Example of research engines includes Linux, OpenOffice.org, and Mozilla Firefox used to provide information relating to business. Another role of internet is enhancement of personalized marketing that allows businesses manufacturing new technologies to market their products to specific people. Examples include My Space, Face Book, Orkut, Twitter and friendster. Communication about new technologies manufactured by businesses through advertisement is another role of the internet (Andrea, Andrew, Michael, 2003).

The use of internet has certain advantages which include first; it is efficient due to low costs making it easily accessible to acquire relevant business information. Second, internet allows businesses manufacturing new technologies to do business fast. A third advantage of internet is that it provides businesses with the capacity to gather opinions about their products from end users and other professionals. Fourth, internet provides businesses manufacturing new technologies with the capacity of trying out new ideas necessary for improving performance of the business.

2. During this course (BA545 Emerging Technologies) we discussed Pull and Push technologies. Provide three examples of each, and talk about the advantages and disadvantages of Pull and Push technologies.

Pull technologies requires the user of internet services to actively research and retrieve information necessary for research or any other stipulated purpose. The pull technology is a network communication style whereby request for data is initiated by the client and response provided by the server. Examples include the web, library and Usenet newsgroups. Advantages of pull technologies include acquisition of first hand information, encourages research and it is easy to use. On the other hand, disadvantages include high costs for conducting research, requires thorough training and failure to handle adequate bandwidth.

Push technology on the other hand is an internet based communication style whereby request for information or any other internet service is initiated by the central server. It is based on information preferences which are expressed in advance. Examples include email, television and radio as they deliver information to the user. An advantage of push technologies includes ease of use as minimal effort is required by the recipient to receive information. The ease of use feature has made email a more preferable web site than any other internet applications. On the other hand a major draw back of push technologies is rapid exposure to technological problems, power failures and virus infections.

3.  You are a systems technologist working in a big Fortune 500 company. Advancement in technological development in the field of business is one of the most critical aspects of the market. Computers have changed the way of doing business from manual operations to electronic trading called e-commerce. This is one of the best achievements in the current trends of technology which has led to improvement in business performance. A close look of electronic commerce gives an overview of how technology has led to integration of markets.

The use of internet which connects computers through application of protocols helps traders from different geographical locations to carry on business without movement. Through the aspect of globalization, current technological trends have made the exchange of goods and services to be easy and effective. Technology has made it easy for organizations to advertise their products through the internet hence capturing global markets (Andrea, Andrew, Michael, 2003). This has led to an increase in volumes traded hence leading to high profitability. Sales are made online through the help of technology and this helps to cut down some costs and saves time.

A company using e-commerce has to ensure that it has up-to-speed systems in the aspect of databases, network security and payment methods. Databases are essentials in a company that uses technology to carry on with its operations. The company is supposed to ensure that its systems are efficient to avoid losses and satisfy customer needs. A company using technology is supposed to frequently check on its systems for any technological problems. This helps to maintain efficient and up to speed system which helps to avoid wastage of resources and time.

Online payment of goods and services is one of the most critical aspects enhanced by technology that needs high speed systems. This can be enhanced through the use of wire transfer which ensures that money is received on time. Doing business transactions online require adoption of strong security measures that prevents loss of information and other resources such as money. The use of passwords to access accounts is a major security measure that can be used by organizations. Encryption of information is another important network security consideration.  This helps to deal with hackers as they are protected from accessing accounts of the company and other important business information.

4.      You are an Information Systems educator, and you have been asked to write an article about emerging technologies and how important it is to be prepared to adapt to new technologies (on-time), and the efforts and expenses businesses are likely to spend. Include at least four examples of emerging technologies.

The development of technology in the modern world has led to emergence of certain technologies applied in certain aspects of life. This has drastically changed the way of life in positive and negative aspects. Nearly every activity in organizations, government offices, institutions, homes, health centers and hospitality industry is carried through the use of information systems. Some key emerging technologies include communication, transportation, bioinformatics and entertainment (Andrea, Andrew, Michael, 2003). These key areas of development have been enhanced by application of information technology systems.

In communication, technology has made it possible for individuals to pass information across long distances within a short period of time. This includes the use of mobile phones, electronic mails, fax and social networks such as Face book. The mode of communication has completely changed due to technological advancements. Transportation technology is another key development that has made movement of goods and people to be more easy and cheap. Developments in air space and road transport systems as a result of technology have made transportation more cheap and easy. Bioinformatics includes the aspects of genetic engineering and photosynthesis which has led to increased level of production. The entertainment sector has changed since the development of information systems.

The use of televisions, radio, computers and other electronic gadgets have led to a change in entertainment field. The changes resulting from technological advancement calls for proper arrangement by individuals within the key sectors affected. It is important to be prepared about the changes so as to avoid making losses and face the challenges associated with new inventions.  Businesses have to take appropriate measures on time such as communicating to customers about the changes to avoid embarrassment (Andrea, Andrew, Michael, 2003). Embracing new technologies by businesses results to creation of more expenses such as training, purchase, maintenance, installation and inconvenience costs. Business owners have to be prepared to deal with such costs for better performance of organizations.

My Favourite Retail Environment: All Saints Before you enter the shop, All Saints have set their tone. Headless mannequins hang on chains, enclosed by dark grey walls; the window display at the front of the shop is bleak yet the simple nature portrays the beauty of the garments. The surrounding windows are tinted, therefore you can see out but not in; this gives the shop an exclusive feeling, contributing to the individual style of the clothes and the high price tags.

The building is the main feature of All Saints which sets it apart from other high street shops; it’s a converted bank, however it’s been renovated to look and feel like a church, this view is gained from entry as you step through the huge wooden doors. The ceilings are high, the arches, pillars and cornices are incredible, the tiled floor is amazing, and the centre of the store has a beautiful round ceiling mural with a balcony surrounding and a trio of gold, goblet type ornaments.

The shop is very gothic in style and having every wall painted a dark grey colour contributes the styling of the clothes and the mood the shop puts you in; it’s like a fantasy world where the Victorian era meets modern Soho or downtown New York. Lighting in the store consists of spotlights on the ceiling pointing down at each fixture or display of clothing; this provides great contrast to the blandness of the colours and also highlights the garments beauty.

The spotlights also contribute to the exclusive, almost celebrity feeling as they transform the store into a kind of set, depicting a story, as would be done in a movie. There is a hanging cruciform, created from very bright, stark naked bulbs. This creates a very artistic and creative view and a rock ‘n’ roll feel within the store, allowing the consumer to really understand the innovative and conceptual brand they are purchasing from.

The theme of crosses is continued throughout the store and also features on the giant iron crest outside the store. The fixtures on the wall are created to be in the shape of a cross and the ends of each arm have a small cross logo. The fixtures are like scaffolding and the display cabinets are giant old wooden tables or big heavy draws and cupboards with huge locks and chains. The displays are incredible with huge butcher style hooks, warehouse style chains and metal, old head neck dummies ripping at the seams and skull candles.

The store has depressive modern music playing in a relaxed manner, contributing to the contemporary feel and making the shopping experience more pleasant. There is no ‘perfumed’ smell to the store; yet it has a kind of musk which smells like old vs new. All Saints’ staff is incredibly attentive and great at selling in a non-pushy manner. Overall the store is very open plan; the distressed feel and glamour meets grunge cool is inspiring and that is what makes ‘All Saints’ my favourite retail environment.

HOW CHANGING ENVIRONMENTS AFFECT ORGANIZATIONS

• Environmental change: The rate at which a company’s general and specific environment changes
•  Stable environments: the rate of environmental change is slow
• Dynamic environments: the rate of environmental change is fast
• Punctuated equilibrium theory: companies go through long periods of stability, followed by a short complex period of dynamic change (revolutionary periods) to later return to stability
• Environmental complexity: Refers to the number and intensity of external factors in the environment that affect organizations
• Simple environments: few environmental factors Complex environments: many environmental factors
• Resource scarcity: Refers to the abundance or shortage of critical organizational resources in an organization external environment
• Uncertainty: How well managers can understand or predict the external changes and trends affecting their business
• Uncertainty is lowest when environmental change and complexity are at low levels and resource scarcity is small (if environment is not too complicated and doesn’t change much it’s easy to predict) .

FOUR COMPONENTS OF GENERAL ENVIRONMENT

1. Economy * It influences basic business decisions such as whether to hire more employees, expand production, or take out loans to purchase * In a growing economy more products are bought and sold, more people work and salaries rise; and viceversa (in shrinking economy) * Business Confidence Indices: shows how confidente actual managers are about future business growth
2. Political/Legal Trends Includes legislation, regulations, and court decisions that govern and regulate business behaviour * New laws and regulations continue to impose additional responsibilities to companies
3. Sociocultural Trends * Demographic characteristics, general behaviour, attitudes and beliefs of people in a particular society
4.  Technological Trends * Refers to the knowledge, tools and techniques used to transform inputs into outputs

 FIVE COMPONENTS OF SPECIFIC ENVIRONMENT

The specific environment is the environment that is unique to a firm’s industry and that directly affects the way it conducts day-to-day business.

1. Customer: * Monitoring customer’s changing wants and needs is critical to business success. It can be done in two ways: i. Reactive customer monitoring: identifying and addressing customer trends and problems after they occur ii. Proactive customer monitoring: identifying and addressing customer needs, trends and issues before they occur
2. Competitor: Companies need to keep close track of what their competitors are doing * To do so, they perform a competitive analysis * A competitive analysis involves deciding who your competitors are, anticipating competitors’ moves, and determining competitors’ strenghts and weaknesses
3. Supplier: * Supplier dependence: the degree to which a company relies on that supplier because of the importance of the supplier’s product to the company * Buyer dependence: the degree to which a supplier relies on a buyer because of the importance of that buyer to the supplier’s sales * A igh degree of supplier or buyer dependence can lead to oportunistic behaviour (benefiting at the expense of the other) * In contrast, relationship behaviour focuses on establishing a mutually beneficial, long-term relationship between buyers and suppliers
4. Industry Regulations: * Regulations and rules that govern the practices and procedures of specific industries, businesses and professions * Unlike the political/legal component of the general environment, this does not affect all businesses
5. Advocacy Groups: These are groups of concerned citizens who band together to try to influence the business practices of specific industries, businesses and professions * e. g. environmental advocacy groups try to influence manufacturers to pollute less * Ways in which advocacy groups can influence businesses: iii. Public communications: voluntary participation of media industry to send out the group’s message iv. Media advocacy: involves framing the group’s concern as public issues that affect everyone, forcing media coverage v. Product boycott: advocacy groups actively try to persuade consumers not to purchase a company’s product or service

MAKING SENSE OF CHANGING ENVIRONMENTS

Because external environments can be dynamic, confusing and complex, managers use a three-step process to make sense of the changes in their external environments:

1. Environmental scanning: * Searching the environment for important events or issues that might affect the organization * Manager scan the environment to reduce incertainty
2. Interpreting Environmental factors: * After scanning, the company determines what environmental events and issues mean to the organization. * Distinguish environmental events as either threats or opportunities
3.  Actiong on threats and opportunities: * Managers decide how to respond to these environmental factors * Because it is impossible to comprehend all the factors and changes, managers rely on Cognitive maps that summarize the perceived relationships between environmental factors and possible organizational actions

INTERNAL ENVIRONMENTS – ORGANIZATIONAL CULTURE

Organizational culture is the set of beliefs, values and attitudes shared b members of an organization.

• Creating an Organizational Culture: * The founder is the primary source of an organization’s culture
• Founders create organizations at their own image
• When founders are gone, culture is kept with: i. Stories: to emphasize culturally consistent assumptions, decisions, and actions ii. Heroes: people admired for their qualities and achievements within the organization. Successful Organizational Cultures:
• Are Adaptable * Have employee involvement * Have a clear company vision * Are Consistent, Strong culture (even though reduce adaptability)
• Changing Organizational Cultures: * Culture has three levels: iii. Seen (surface level) iv. Heard (expressed values & beliefs) v. Believed (unconscious assumptions & beliefes) * Managers should only focus on the parts of the culture they can control, those are the surface level items and expressed values and beliefs

Chante Hamilton Maturity Maturity. What makes an individual mature? Maturity comes with age and time. It is the ability to make wise decisions. It is also the way in which people act toward different situations. Maturity can be shown in the way organisms develop. Society claims that females mature faster than males, physically and emotionally. However this is not necessarily true because everyone grows differently. Although maturity has much to do with aging, it can also be seen in the way animals and plants grow. Almost anyone can identify the difference between a mango seedling and a fully developed mangola .

The contrast is obvious. A mango seedling is small, hard, bitter and green. On the other hand, a mangola is large in size, bright yellow and succulent due to its maturity. This instantly brings to mind the origin of the word mature. The word is derived from the Latin term ‘maturare’ which means “to ripen”. We can also see maturity in animals. For example, a toad and a tadpole are completely different in structure. However, a tadpole changes into a toad due to metamorphosis. A tadpole is limited to only a tale and a head and is incredibly. Whereas a toad particularly bulky and has webbed feed, protruding eyes and lacks a tale.

Maturity is also shown in the way human beings grow as they age. In this case, some people mature faster than others. The body of an adolescent female is far less developed than an adult female. A mature female has broad hips and large busts compared to younger females who lack such assets. Body maturity also applies to males. When a male is young his entire body has a “young” look. His shoulders are not broad, his arms look a bit wimpy and he has little to no facial hair. However, a grown male has facial hair, he is taller, his arms and his chest and shoulders are built. Recently I’ve witnessed just how immature some people can get.

Politicians of the PLP and FNM exposed each other’s personal life to the nation as if it were concerned anyone. They did this just to gain more votes. Anyone that can stoop this low has to be immature. To be immature is to be mentally primitive. It causes human beings to display a “childish” attitude towards others. They should have played fair and worked in their constituencies to the best of their abilities. That would have been the mature thing to do. Immaturity is also seen at its best in young children. For example, as a child I would throw the biggest of tantrums whenever I candy and “no” was the answer.

I would cry, scream and throw things over until I accepted the fact that I just was not getting the candy. Now, as an adult I can hear the word “no” and move on because of the level of maturity I’ve gained over the past few years. The best way to show maturity is to show our knowledge instead of bringing childish acts to the table. Each and every one of us has the ability to do so if we would just think before we act. We should also show respect for our peers and give help where it is due. Maturity is also shown through manners, courteousness and being graceful. All of these things are what makes an individual mature.

Introduction

The development of the world around us has been increasing rapidly in many areas during the past years.

As a result of the development the human lifestyle has become easier and efficient. Unfortunately these benefits from development have come at a price, the price been environmental pollution. The developing process affects the environmental stability of the world in many different ways such as climate change, global warming and health hazards. With the intention of preventing or minimizing these negative effects, governments and other officials have brought forward many environmental regulations. These regulations have an influence on our daily lifestyle and on how industries operate.

The history of environmental regulations in Europe goes back to the 19th century when the industrial revolution took place. In 1972 European officials introduced environmental policies with three main objectives. The main objectives were to prevent and reduce environmental damage, to support environmental stability and to balance the use of natural resources. Since then the environmental policies has been changing and affecting many industries around the globe. Some main industries include the building industry, automotive industry, manufacturing industry and aviation industry.

Different industries handle environmental regulations using different approaches and the specific impact on the industry differs from one to another. Although the impact on the industries differ the general out comes by enforcing regulations will remain the same. It is vital to look in to the bigger picture of global environmental protection rather than just concentrating on minor drawbacks which can occurs during the protection process. [EU Environmental Policies,2006] Environmental regulations also have a significant effect on the general public.

It is reasonable to state that environmental policies have changed almost every aspect of our lives. Presently more and more people consider been eco-friendly which can be seen from their decision making. There is a direct link between the public and the industries. If the industries introduce more eco-friendly products the public will appreciate them and will consume, the best example for this is the hybrid car. This scenario also works the other way around; if the public insist to have more efficient and eco-friendly products the industry will fulfil their needs.

By making this connection stronger it will be easy to restore environmental stability and maintain it with less aggravation. Industries have taken many steps to minimise pollution and to prevent future pollution. This project will look in to the environmental impact on the aviation (aerospace) industry and how it will affect the future of the industry and it will also investigate where the aviation industry stands presently when it comes to environmental regulations. Aviation pollution is highly experienced in and around airports.

This is the reason why I selected this specific project. My future plan is to study further on Airport Planning and Management; furthermore my ambition is to work for my country “Sri Lanka”. Sri Lanka is a developing country which has less experience on the subject of environmental pollution which is another reason for me to select this project. Objectives In order to make the progression of the project easy, the project is carried out in three main stages. This will also help to be on track according to the project plan; these three stages are illustrated as following.

Stage 1 – This stage helps to get an idea on what the project is really about and gives an idea what to expect in the future. Stage one mainly involves general broad reading.

Objectives for stage one is as follows.

• Planning the project
•  What is environmental pollution about
•  The history of the regulations established to protect the environment
• Critical analysis of environmental regulations
• How environmental regulations effect the general public
• Environmental regulations and different industries
• Future of the regulations
• Introductions to aviation and environmental regulations
•  Any other general reading

Stage 2 – The stage two helps to build up own opinions and gain more information on the actual subject. One other main objective in stage two is to think about possible applications for the project. The objectives for stage two is as follows.  Altering the project plan if needed

•  Regulations on the aviation industry
•  How the industry act according to the regulations
•  How different is the aviation industry when compared to other industries
•  Building up an own opinion on the subject
•  Possible applications for the project
•  Report submission (the planning report)

Stage 3 – This is the final stage of the project where the possible application is developed based on own opinions of the subject. The reading done in this stage should be more specified on the subject. By doing research it is important to do an in-depth analysis of specific subject data. By stage three the application of the project should be specifying a particular subject, if the application is too general or talks about many issues it will be hard to reach to a conclusion for the project. The objectives for stage three are as follows.  In-depth reading on specified subject area (aviation) Working on one specific application

•  Coming to a conclusion based on the specified application
•  Presentation on the project
•  Report submission (final report) Deliverables General aim of the project was briefly explained earlier in the introduction.

If it is to be recapped again, the general aim is to evaluate the impact by environmental legislations on the aerospace industry. For this particular topic there can be many end applications since it is a broad subject area, therefore it is important to narrow the subject matters into a one specified section and continue with the application.

By the time the application is completed there will be some deliverables. To explain the deliverables a probable application is used. The application used here might not be exactly the same as the final application of the project since it is only an initial application. Application – Air Traffic (aviation) and environmental legislation

What will be looked into? (What will be found out during the project? )

• How airlines operate (in the EU and Global)
• Growth of the air transport *
• What is the impact
• What is the attitude from the airlines towards the regulations
• Environmental damage including the present past and future
• What will be the future for the aviation under the regulation
• Comparison aviation to other industries (environmental aspects)
•  Some other points ( manufacture of aircrafts/economy/other related pollutions)
• Finally criticizing the analysis with the own opinion Deliverables change according to a selected application.

One other possible application that can be use is to look in to the manufacturing of aircrafts, materials used and how waste is treated according to environmental legislations.

In order to gain all the mentioned deliverables the project should be at the end of stage three as stated in the objectives. Since this project is still at stage two the deliverables might change as the project progresses.

Literature Review

(Findings up to date) The initial literature review was done in three categories which are,

1. General (any industry other than aerospace) environmental issues and legislations.
2. Environmental legislations and issue on manufacturing industry and materials.
3. Aerospace related environmental legislations and issues.

This way of reading was used to make sure that a broad general knowledge is gained on environmental subjects before stepping in to the specified topic. General environmental issues and legislations History of the environmental policies, legislations and organisations [EU Environmental Policies,2006] As mentioned earlier in the introduction the Environmental Protection Agency (EPA) first brought forward official policies in 1973. Up to now 5 major regulation changes were done by the EPA. Changes were done to address current environmental issues which existed during specific times.

EPA gatherings during the past years is as following,  1st EPA 1973 – Made rules to save water, air and soil. Since it was the first EPA many other new rules were established.  2nd EPA (1977-1981) – Did not publish any new regulation. It was held to review the progress of the first EPA. 3rd EPA (1982-1986) – Discussion on the impact of environmental legislations and economy. Emission rules and how to effectively get rid of waste.  4th EPA (1987-1992) – Increasing the general quality of the regulations. Introducing taxing and emission permits.

Discussion on waste cycles. Analysing impacts on the economy caused by environmental regulations. Discussion on climate changes. Last EPA up to date (1997-2003) – Renewal of emission standards.  Nest EPA – climate change, natural resources, recycling etc. A critical analysis of EU environmental legislations [EU Environmental Policies,2006] Environmental regulations change all the time.  In some cases environmental regulations has an influence on economy.  It has been 30 year from the beginning of the EPA but still they are unable to complete some projects.

Natural resource use has been increased and destruction of natural habitats has also increased.  The laws are not effective and regulations are not accessible for the public. The public should be educated more about pollution. Construction industry and environmental impact [Natural Building Technology,2011] The construction industry induce 7% (from the total) carbon dioxide in the UK. Using of buildings induce 50% carbon dioxide.  Getting rid of the waste is a major issue faced by the construction industry. Construction industry requires natural resources such as wood. This leads to environmental pollution. Most of the natural resources are taken from China, India and South East Asia, therefore the damage is not directly done to the county where buildings are constructed. Environmental legislation impact on the automotive industry [The Open University,2003]  First emission standards were introduced in 1959 for carbon monoxide and hydrocarbon emission.  Most of the world use emission testing for vehicles.  The regulations are tight on the diesel engine use.  Due to the regulations engine life p is getting less and new designs are introduced frequently. Regulations has changed customer point of view.

They are looking for more efficient engines with less noise for a reasonable price. Due to the hybrid and electric vehicles the future of the diesel engine is not promising.  Environmental legislations and issues on the manufacturing industry and materials Environmental Materials [UK Centre for Materials Education, 2011]  Stages of material usage include extraction, production, product design and disposal.  The subject environmental materials look in to the material structure, chemical and physical properties. Other than that it also looks in to the economical point of view. Picture below shows the lifecycle of a material Diagram 01, Life Cycle Analysis [UK Centre for Materials Education, 2011] The impact of environmental regulations on the UK manufacturing sector [Nottingham University, 2011] In a country the economy and environmental pollution is not proportional if that country has proper regulations. Current regulations act as a helping hand towards the development.  Some regulations are not helping innovation.  More flexible regulations are good for the economy.  UK manufactures always select the short term regulations.Many companies now use materials with produce less waste. . Aerospace related environmental legislations and issues. Growth of aviation [Professor John Whitelegg ,2000]  Since 2006 the growth has been 30% and it will double by 2020. The growth from 1995 to 2015 is nearly 300%.  Aviation has the highest growth rate of all modern transport methods.  Global revenue passenger kilometres (RPK) increased by a factor of 4. 6 (since 1970-1995). RPK growth for different regions are- North America 27. 5%/Europe 12. 5%/America to Europe 11%/ Asia to America to Europe 12. 7/rest of the world 36. 5%. But by today Asia (china and India) has the highest RPK due to the rapid development. By 2015 310 million passengers will go through UK airports (in 1995 it was 126 million). Noise pollution by aviation[Professor John Whitelegg ,2000]  The noise pollution is commonly experienced around the airports. Officials claims that the noise footprint of the UK airports has gone down, but complaints from the public against the new terminal 5 in Heathrow airport proved that claim was wrong.  In Netherland noise pollution by aircrafts is 12%.  UK officials claim that the number of people exposed to noise pollution has rapidly gone down, but Germany had done an investigation on the same matter and came up with a different claim.

They stated that there is an increase in the number of people who are exposed. Noise pollution effects human health in many different ways. Pollution by aircraft emission [Professor John Whitelegg ,2000] Gasses which pollute the environment – carbon monoxide/ nitrogen oxides/ ozone / particulate matter (PM)/ volatile organic compounds (VOC)/ sulphur dioxide.  UK officials claim that aviation pollution is insignificant, but US data for Zurich and Stockholm airports show that aviation emission pollution is significant in well-defined geographical area. Table below shows the Heathrow airport annual emission data Diagram 02, Heathrow airport annual emission [Professor John Whitelegg ,2000]  Prediction shows that by 2050 carbon dioxide will increase by 588% and nitrogen Oxide by 411%.  Aircraft emission at upper troposphere and lower stratosphere can cause serious climate change problems. Policy measures and management in aviation [Professor John Whitelegg ,2000]  There are fewer regulations for the aviation industry when compared to other industries.  Aviation industry should also follow regulations as other industries do. Current environmental regulations on aviation are out dated.  Aircraft fuel is not under any taxing.  To control pollution it is important to manage the transport demand.  If a new regulation is introduces it should be introduced step by step. All the above mentioned points are from initial literature review. These data are brief descriptions obtained from broad reading. More detailed data are available in the log book.

Gantt Chart

The time period from 29/09/11 to 25/11/11 represents the stage one and two from the objectives.

By the time this report is completed this section will be completed. Stage one and two has only got four slots allocated and it is only a quarter of the total slots available. This shows that the amount of work which has to be done in stage 3 is comparatively high. The time allocation for specified reading, preparation for the final report and project seminar report and poster submission is relatively high. These are very important tasks of the project therefore they are going to consume more time relative to other tasks. The third stage starts on the 26/11/11 and it ends on 26/04/12.

Note – A full sized Gantt chart is attached in the appendix.

Discussion

The initial literature review shows general connections and areas where environment regulations have failed to achieve the required results. The regulations have been there for almost 30 years now but still most of the issues are not completely solved. Greenhouse gas emission has considerably decreased during the past years, but the rate of decline is not that impressive. The natural resource use has also rapidly increased up to a point where the general public can feel the effects of it.

It is fair to say that the world is in desperate need of finding alternative sustainable energy methods to survive in the future. There is a hidden truth behind the use of natural resource by developed countries. Most of the developed countries have limited their natural resource use but in order to fulfil their needs, natural resources are imported from other developing countries. This may seem great on the developed countries side but what they do not realise is the fact that negative effects from harvesting natural resources (no matter where it comes from) is going to be global.

By going through the data I feel like the environmental regulations has gone easy on the aviation industry when compared to other industries. Best example for this is the fact that automotive emission percentages are declining while aircraft emissions are on the rise. As an excuse for this most officials (mainly in the UK) compares data from 30 years back and claims, there is a drop in emission levels, but what they are not doing is, comparing data with other industries. If the emission is compared with other industries it will be glaringly obvious that more work should be done on aircraft emission standards.

One main reason for the slackness towards the environmental regulation on aviation industry is that aircraft traffic only contributes a small percentage towards the total pollution of the planet. But this claim is not that accurate, it doesn’t take in to account the manufacturing process of aircrafts, natural resources used in the process and vehicle emissions due to airport traffic. Emission is not the only environmental problem caused by aviation, noise pollution is another main issue caused by aviation. New research shows that exposition to high noise levels can cause serious damage to people.

People who are continually exposed to high noise levels are more likely to gain noise related health issues, due to this fact living near airports can be a prime reason for health hazards. Likewise there are many unsolved problems involving the environmental pollution and aircraft industry. More details regarding issues and practical solutions for the issues will be researched and criticised in the next stage of this project. Furthermore an appropriate application will also be used to narrow the subject in order to make it more specific.
