There are, for example, some 30,000 chemicals in common use today in dyes industries, any one of which may be released into the environment during processing or use. Due to its toxicity, widespread presence and complex nature, this type of pollution is a serious problem. In Modern life style, urbanization and develop the use of dyes and dye -based products grows.

However, there are a number of advantages to bioremediation, which may be employed in areas which cannot be reached easily without excavation. The foundation of bioremediation has been the natural ability of microorganisms to degrade organic compounds. Bioremediation is not a panacea but rather a natural process alternative to such methods as incineration, catalytic destruction, the use of adsorbents, and the physical removal and subsequent destruction of pollutants. The cost of moving and incinerating pollutants is at least ten times that of in situ biological

Essay on Environmental Pollution: Causes, Effects and Solution

...Essay on Environmental Pollution: Causes, Effects and Solution On February 5, 2014 By Ankita MitraCategory: Environmental pollution refers to the introduction of harmful pollutants into the environment. The major types of environmental pollution are air pollution, water pollution, noise pollution, thermal pollution, soil pollution and light pollution. Deforestation and hazardous gaseous emissions also leads to environmental pollution. During the last 10 years, the world has witnessed severe rise in environmental pollution. We all live on planet earth, which is the only planet known to have an environment, where air and water are two basic things that sustain life. Without air and water, the earth would be like the other planets – no man, no animals, no plants. The biosphere in which living beings have their sustenance has oxygen, nitrogen, carbon dioxide, argon and water vapour. All these are well balanced to ensure and help a healthy growth of life in the animal world. This balance does not only help the life-cycles of animals and plants, but it also creates the perennial sources of minerals and energies without which the human civilization of to-day could not be built. It is for this balance that the human life and other forms of existence have flourished on earth for so many thousands of years.

However, development also has some negative impact on society. In addition, the negative impact of development is becoming more serious, especially in developing counties. In this essay, the term ‘the social cost of development’ refers to damage to society caused by activities aimed at achieving the goals of society. The concept of the ‘development’ is considered to include the development goals and all systems and legal measures used to achieve development. Further to this the concept that social cost is‘too high’ is considered to mean that too much damage is caused to society before it is possible to achieve the development goals. In view of the above this essay will argue that the social cost of development is too high. This will be demonstrated by analysing of the impact of the social cost of development on the environmental pollution and health. Developing countries will cost the environment to develop the economy. A major reason for this is that it is commonly that in older to solve the poverty, developing countries will cost the environment to develop the economy. Firstly, during economic growth, environmental degradation will increase. According to the result of research by Dinda, “When a country achieves a sufficiently high standard of living, people attach increasing value to environmental amenities”...

International bodies such as the Kyoto Protocol, the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Environment Programme, have stressed the importance or reducing pollution and emissions in developing countries in order to maintain sustainability. Cancer villages are becoming a major concern in China and that was enough to make the Chinese political party to take responsibility and change their views on the ecological environment.

...Environmental studies and Fore by admin on Monday, December 12th 2011 No Comment in Essay examples Tags: Environmental studies and Fore, Environmental studies and Fore essay There have been several environmental changes in the world recently occurring due to the pollution of the environment. Increase in production, manufacturing, the use of motor vehicles and basically dumping waste into the environment. This has brought about different types of pollution, each resulting in negative effects due to reducing quality air and other environmental features. If things keep going down this road, the future generations may not have a clean environment to come to, and it may even signify the end of our world. Some of the major environmental pollutions include air pollution, sound pollution, soil pollution and water pollution. Air pollution occurs due to some dangerous gases being released into the environment in large quantities. If the gases are released in small quantities and over a long time, the environment has ways of cleaning itself out, but due to the increase in development and population, this is not possible. This threat for the future world has become a world issue which requires a quick and fast measure taken against it. Otherwise, we might just destroy the only thing that rejuvenates itself and supports our ecosystem. It has been clear though from the past that this issue will not be gotten rid of so easily. This is because even the problem itself...

The Paper

...reactions. Is water natural? Imagine not being able to drink clean water as a result of pollution. Water pollution is a very critical environmental issue and is harmful to the health and life of both humans and animals. Humans around the world must become aware of the dangers and the role they play in the quality of the water around them and improve in the ways water pollution is treated. In this essay, one will ascertain a thorough understanding of some of the causes and some of the dangers of water pollution and ways to prevent it. Even though water is a vital part of human life, many of the causes of water pollution come from humans and their ignorance. To name a few, water pollution is caused by agricultural runoffs, leaking sewer lines, and accidental leaks and spills. Agricultural runoffs are the result of manmade products like pesticides, insecticides, or herbicides and other waste from a large area of land. These products are made to help crops during their growth process and prevent them from being eaten by insects. As a result, these chemicals are washed into waters through natural processes that form increased nitrates and phosphates that are harmful to humans and have a very harsh impact on the environment. Global warming aside, agricultural runoffs are considered one of today’s biggest environmental threats. Leaking sewer lines are another cause of water pollution. Sewer lines are manmade instruments that carry human waste to different industrial plants...

The Air We Breathe

...“Is Air Pollution a Belief?” Winter-Koger’s essay “What on Earth Are We Doing?” discusses many environmental problems, e.g.: ozone depletion, global warming, overpopulation, deforestation, air and water pollution, topsoil loss, and coral reef destruction. While it is difficult to isolate one problem to discuss, as they are all equally, important environmental problems; I have decided to research the effects of outdoor air pollution. I am interested particularly in whether the United States has made any positive changes for cleaner air, or added to the negative impacts on two of six different types of air pollution-ozone(smog) and particle pollution (particulate matter) since Winter-Koger’s essay (2004). Air pollution is one of the many environmental problems faced each day around the world. Man has always been a solid contributor to environmental pollution, a problem passed on from generation to generation. Air pollution is not a belief that one has; but a real problem that absolutely does exist. Many people have dedicated their lives to finding a solution to the detrimental effects of air pollution. And many people, unknowingly, and some ignorantly, have dedicated their lives to contributing to air pollution. To better understand the effects of air pollution, one must first understand the definition of air pollution and how it is caused. You may disagree and feel you know the definition of air pollution; but ask the person next to you to define air pollution, and soon...

Pollution

...Pollution of the environment in general is an issue in the area that I live in. There seems to be a trend of pollution just in general by the population of people. There are traces of trash, chemicals dumped, waste not properly disposed of, and pollution in the air due to vehicles with improper emissions. Pollution like this can find its way into important resources like water supply, food supply, and the very air the population breathes. In this essay, I'm going to describe the issues of environmental pollution, and the problems that could be tied to them. Pollution of the environment is an issue that is an issue throughout the country. It is one of the greatest challenges to combat due to the fact that it takes the participation of all citizens in order to deal with the issue of environmental pollution. Some people are not even aware that environmental pollution could be the catalyst in many different diseases that some have come across. Unfortunately, what people don't know, they can not take action against because they do not understand the problem. When the subject of the environmental health comes up especially with regards to a small town, one of the main concerns that could come about is the quality of the water if there is pollution. Water is an essential source to all forms of life, so if it is polluted, that means that it has access to contaminate any forms of life. It should be said that the water quality is extremely important to human...

Kellogg's Case Brief

...Most people would accept that one of the highest priorities today is to find a solution to the various environmental problems facing mankind. It has been suggested that the best way to achieve this is for government to raise the price of flue. It is acknowledged in this essay that, however, this is not necessarily the case. However, this practice probably has insignificant influences on reducing the environmental pollution. If raising the prices of fuel, it might lead to the reduction in the number of vehicles utilized by people due to the higher expense. Nonetheless, we can not deny that there are a large number of plutocrats who already own a tremendous property using the cars as well, most of whom may not care much about the uplifting of flue’s price, and then they will utilize the vehicle as usual as before even with the higher price. Thus, the problems of environment could not be tackled completely and effectively. On the other hand, there are still other environmental problems left unsolved. The worsening/deteriorating world, particularly in these decades, witnesses an increasing variety of pollutions such as water pollution, deforestation and global-warming. As vehicle emissions is neither the major nor the sole cause of air pollution, rising price is very much likely to be ineffective in solving the problem of air pollution, let alone other pollutions. Hence, the environment cannot be improved just by the approach of raising the price of fuel. Overall, concerning...

Why Are Environmental Failures Considered to Be an Example of Market Failure?

...(a) Why are environmental problems considered to be an example of market failure? Environmental problems are considered to be an example of market failure because environmental problems not only compound poverty and low standards of living, but the problems of common access resources or weak regulations result in massive negative externalities and a significant threat to sustainability. Market failure is defined as when community surplus is not maximized due to problems preventing resources from being allocated in an optical manner. Negative externalities, also used in this essay, is defined as a decision or a product that leads to it having a larger society cost than private cost. This essay will be split into different parts to tackle this problem: 1) Examples of market failures and environmental problems 2) Explanation of environmental problems as negative externalities 3) Allocative inefficiency and overproduction at free market price due to marginal social cost being larger than marginal private cost There are different ways of market failures. Firstly, the lack of public goods is a market failure. Public goods are goods that would not be provided at all in a fee market. Since they are goods that are of benefit to the society, the lack of public goods in the free market is considered to be a market failure. (…) However, the main focus of this essay would be on the existence of externalities, which is a type of market failure as well as the negative externalities...

Air Pollution

...However this situation has also brought about the regrettable result of environmental pollution. Especially, air pollution is one of the serious environmental pollution problems because of the impact it has had on organisms on the earth. For this reason, it is necessary for governments to spend more money in order to stem this pollution. In this essay, I will explain about this point of view. Firstly, people struggle to live with the severe diseases which are caused by air pollution. Respiratory and cardiovascular diseases are representative diseases. In East Asia, For example, 130,000 premature deaths and 50-70 million incidents of respiratory illness occur each year. Moreover, according to research, the incidence of cardiovascular disease and death are associated with the long-term exposure to air pollution. For these reasons, it is clear that air pollution has a harmful effect on human’s health. Another reason is that air pollution has resulted in serious complications in the natural environment. For instance, global warming, which is caused by greenhouse gas in turn caused by air pollutants, increase the average temperature of Earth’ atmosphere and oceans. Acid rain is caused by air pollution, it makes manmade structures, rock formations, forests and other natural landmarks quickly deteriorate. It also causes fish kills and other detrimental effects to aquatic environments. Therefore, air pollution brings significant problems to the natural environment. Finally, governments...
