Concern for environment has increased and spread over recent years. Pollution-a major environmental concern. Types and sources and effects of pollution. Causes and associated kn. Remedial measures-existent and suggested. Plato lamented the destruction of soils and forests in ancient Greece. Shot and Engels polluton eloquently of the wretched conditions read article by the Industrial Revolution.

But the surge in concern about environmental quality fpr the last three decades has hsort uniquely widespread and impassioned. Appreciation of the material and spiritual importance of a healthy natural environment has spread. Perhaps the most dramatic intellectual shifts are occurring in the Third World, where understanding of the ecological under spinning of human life-largely lost in the post-war dreams of industrialisation is on the rise.

The new interest in environmental quality complements recent shifts in thought polllution development theorists, many of whom esswy stress the need to address the basic needs of the poor directly rather than hope that the benefits of growth will trickle down to them. Improving the lot of the under-class and protecting environmental quality can stjdents mutually-supportive goals.

Both internationally and within nations, the new appreciation of our bonds with nature has spawned new institutions and policies-new UN and governmental agencies, new laws, altered aid programmes, new international treaties. Yet for the most part, responses remain inadequate to the needs. For the most urgent need today is to protect and preserve what remains of the environment. To do that one has to understand the meaning of pollution and consider ways of tackling it. It takes place through changes in energy patterns, radiation levels, chemical and physical constitutions, and abundance of organisms.

It includes release of materials into atmosphere which make the air unsuitable for breathing, harm the quality of water and soil, and damage the health of human beings, plants and animals. Air pollution in one form or another has accompanied human society from the beginning. Despite the successes registered against smoke, the pollution of city air by other products of coal combustion above all, Sulphur dioxide and by nitrous short essay on pollution for students, hydrocarbons, pollutoin wastes, esay carbon mon oxide continues to worsen in most of the countries.

Strong evidence indicates that prevailing levels of air pollution contribute to the ;ollution of chronic respiratory diseases emphysema, asthma, and chronic bronchitis besides short-term respiratory afflictions as well. And those living near smelters and refineries often face increased cancer risks because of the toxic substances spewing from smoke-stacks. Over the last 25 years, many countries have begun trying to regulate the flow of pollutants in the air, Air pollution can no longer be addressed as studrnts a local urban problem. Thermal pollution of water. In general, pollution from so-called point sources like sewage pipes and factories is under progressively better control.

But the contamination of waterways from diffuse sources-run-off from farmlands which tends to carry fertilizers, pesticides, and organic matter, and from urban areas, which often fo oil, metals, and other pollutants-remains largely uncontrolled and is on the increase in most countries. Acids and heavy metals falling with the rain constitute additional sources of water degradation.

The problem of water pollution is growing day-by-day; today a great many people are deprived of disease-free potable water, as almost all the sources of water-from short essay on pollution for students to wells-are increasingly being infested with different kinds of pollutants.

What is pollution?

Besides causing immense disturbances, there are increasing case of pulmonary tuberculosis and thrombosis and various sorts of brain and heart complications. Reducing the amount that we buy, reusing and repairing items wherever possible, and recycling as much as we can will all help to reduce the amount of waste dumped in the environment. Suspended matter consists of dust, fumes, mist and smoke. You may order any type of non-plagiarized sample paper from us — essays, reports, reviews, term papers, research papers, theses, dissertations and more. The water of rivers and seas is being constantly polluted all over the world by various dangerous chemical and biological wastes. I asked my writer to correct it and got a paper that fully met my demands. Nowadays, children are leading the environmental revolution. Humans use a lot of stuff! You have helped me a lot!

Soil pollution usually results from the disposal of solid and semi-solid wastes from agricultural practices and from link habits. Fallouts short essay atmospheric pollution also contribute to soil pollution. Direct pollution of the land by pathogenic organisms is also important.

Thus the soil is heavily polluted day-by-day by hazardous materials and micro-organisms, which enter the food chain or water and are consequently ingested by man. As a result, there are numerous health problems. Those bacteria which pollution transmitted from air to soil infect man causing bacillary dysentery, cholera, typhoid and paratyphoid fever. Flies which breed or get in stufents with the contaminated soil become carriers of disease organisms. The eggs of some of the parasitic worms get incubated in the soil and both the eggs and larvae are infective.

Radioactive pollution of the environment is due to the increase in natural background radiation, emerging from the short essay on pollution for students of man involving the use of naturally click at this page or polluion produced radio-active materials.

The chances of radioactive materials Spreading into the air have increased extensively as a result of the discovery of artificial radio-activity, and particularly due to the development of fof bomb and of techniques of harnessing nuclear energy. Biological organisms including human beings are subjected to radioactive contamination either by consumption or inhalation. This radioactive pollution may cause cancers, abnormal births and mutations in men.

  • Even if I give a very short deadline, your writers still manage to send me the paper with interesting content.
  • Sometime, farmers use insecticide and fertilizers excessively.
  • His quest for knowledge and search for security succeeded in exploring newer and wider avenues of mysteries that remained baffling so long.

Chronic stusents to radiation leads to leukemia in an individual and go here even an unborn child. Thermal pollution denotes the impairment of the quality of environment air or water by a rise in its temperature. The processes of life involve many see more reactions, and the rate of these chemical reactions vary according to the changes in temperature.

Apart from biochemical reactions, temperature is considered vitally important to physiology and in controlling reproductive cycles, digestion rates and respiration rates. The pollktion of thermal pollution are mainly seen on aquatic animals, particularly fish, on whom the shortt society so much depends. The modern world has a new pollution to face-that of noise.

The scientific approach for considering noise as a pollutant is by decibel. Apart from industrial noises the sources generally are loudspeakers, motor vehicles, trains, aircrafts, processions and read article. Noise need not just lead to deafness. Research has shown that noise pollution is capable of causing ulcers, abortions, cardiovascular diseases, congenital defects and hypertension.

The first and most important cause of pollution is the growing population. The earth is now crowded with people, and all of them consume resources and create wastes. If the per capita amounts of pollutants and wastes were to remain constant, the residue loading of the environment would rise precisely in relation to the growth of population. This is acceptable within certain limits, given the capacity of air, water and land to absorb, dilute, carry away and otherwise render pollutants harmless.

But, unfortunately, in many places these limits have either been reached or have been exceeded. Another important factor is the rapid industrialisation and haphazard urbanisation all over the world. The natural processes which keep the planet habitable in the short-term are primarily cyclic. Materials moving through these cycles utilise solar energy and return to their original state before other tor start. In contrast, modern technology causes materials to be removed from the limited geological deposits or from living systems to be eventually discharged as wastes.

Concern for environment has increased plolution spread over recent years. In order to overcome the problemit is important to identify the sources of pollution. Short essay on pollution for students farming could be one solution for reducing environmental pollution levels. Indeed, many types of localised environmental degradation have global implications. Dickens and Engels wrote eloquently of the wretched conditions spawned by the Industrial Revolution. James I guess other students need to know that your company is very professional and efficient in terms of academic writing services.

Not only do these wastes act as pollutants of the natural cycle but they also alter the composition of the atmosphere and disturb the see more of solar radiation. The ability of the biosphere to withstand these stresses foe further decreased by such conversion of complex natural ecosystems to simple ones.

Haphazard urbanisation makes it quite difficult to provide and maintain the required civic amenities. Some cities have become so large and so crowded that the municipalities fail to properly maintain the sewage, provide clean drinking water or adequate garbage removal facilities. The deterioration of natural systems in poor and marginal areas is at once a symptom and a cause of the extreme misery in which hundreds of millions live.

The pollution problems cannot be isolated from questions of economic progress, political stability, social awareness, migration and international aid. Indeed, many types of localised environmental degradation have global implications. To some degree their causes are also international. Through their way of life and the behaviour of their multinational corporations, citizens of the North can affect environmental conditions in the South. More important, the extent of the extreme poverty that gives rise to so much ecological damage and human suffering is influenced by international monetary, trade, technological and aid policies.

The struggle to preserve xhort environmental quality is unavoidably intertwined with the struggle to improve the lot of the global under-class. The problems are rooted in the society and the economy-and in the end srudents the political structure, both national and international. Foresters know how to plant trees, but not how pkllution devise methods whereby villagers in India, the Andes, or the Sahel can manage a plantation for themselves.

Biologists know where to draw boundaries for nature reserves, but cannot keep landless peasants from invading them to grow food or cut fuelwood.

The solutions to such problems are increasingly seen to involve reforms in land tenure and economic strategy, and the involvement of shhort in shaping their own lives. Applying sensible pollution short essay on pollution for students faces inherent political and analytical difficulties. The direct expense of clean-up measures, falls upon particular industries or groups, while the resulting benefits, even if much large, are less visible and are spread widely in society.

The costs of required controls are tangible and easily figured, but no ready means short essay on pollution for students for totalling the benefits of pollution reduction. The temptation is to engage in extremely narrow accounting, ignoring the immeasurable, subtle benefits of a cleaner environment. The affected industries have shorg strong vested interest in opposing pn required investments, while no single group has an immediate material interest of comparable magnitude in imposing controls.

Thus the political process is distorted, resulting in anti-pollution policies weaker than what is demanded by social interest.

No objective means exist for ascribing value to all the costs of uncontrolled pollution, or to the benefits of reducing it. What is the price of a shortened stuvents life? How polpution one evaluate the spiritual loss of the residents of Tokyo whose sight of Mount Fuji is obscured by smog?

How can we measure the value of a restored and productive ecosystem? The dual judgement about the desirability of anti-pollution measures, then, is inescapably a political one reheating value choices. No economist alone can supply answers to the great environmental policy issues pollktion the day. No doubt, the problems are many and complex even as pollution is growing unbridled. But a failure to control pollution carries and enormous price in the form of bad health and premature deaths of vor beings, other animals and plants; losses of productive ecosystems such as fisheries; losses of recreational opportunities; and degradation of the aesthetic quality of life.

People are gradually losing even the freedom to breathe safely. The all-round depletion is making this planet inhospitable and uninhabitable. Because of the growing pernicious effects of pollution. The Rio Summit on environment is a great landmark in this direction, though, of course, we have short essay on pollution for students wait for some time more for any tangible results. The importance of clean environment and the detrimental effect of pollution have been realised in India as well.

Several legislations exist to control pollution and conserve the environment, with the Environment Protection Act of being the landmark law. But unless the legislations are enforced with sufficient political will, they are rendered useless. Greater participation of the voluntary organisations and an effort to educate the masses on environment and pollution can help to make the Acts effective. If the costs were distributed fairly through studenys, the antipollution struggle would place no serious burden on anyone. Environmental choices must be guided by a vision of a desirable human society and of the quality of the natural environment needed to support that vision.

The noise of ever —increasing number of vehicles does not allow sssay to sleep even at night.
