Improving the lot of the under-class and protecting environmental quality can be 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 Marginal benefits and marginal costs essay 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. In the nineteenth and early twentieth centuries, many cities of Europe and the US were covered with black shrouds of smoke.

American defence and technology company Lockheed Martin recorded net profits of $ billion in 1 alone as a result of the US’ growing military involvement in the Middle East; going back nearly a decade to World War One, unofficial reports have claimed that 21, .

Despite the successes registered against smoke, the pollution of city air by other products of coal combustion above all, Sulphur dioxide and by nitrous oxides, hydrocarbons, petroleum wastes, and carbon mon oxide continues to worsen in most of the countries. Strong evidence indicates that prevailing levels of air pollution contribute to the development 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 simply 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 carries 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 seas to wells-are increasingly being infested with different kinds of pollutants.

Soil pollution usually results from the disposal of solid and semi-solid wastes from agricultural practices and from insanitary habits. Fallouts from 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 are transmitted from air to soil infect man causing bacillary dysentery, cholera, typhoid and paratyphoid fever. Flies which breed or get in contact 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 activities of man involving the use of naturally occurring or artificially 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 atomic 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.

Chronic exposure to radiation leads to leukemia in an individual and affects 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 chemical reactions, and the rate of these chemical reactions vary according to the changes in temperature.Comprehensive and meticulously documented facts about education.
