Today millions of people are without basic needs of cloth, shelter, health, education and employment. This is not due to overpopulation alone but also due to environmental consequences. The loss of forests, fertility of soil, productivity and energy crisis have created many problems. The pollution created by industries, technology etc. and over-consumption by the affluent society lead to the rapid depletion of basic natural resources. Many human problems are also due to mismanagement of environment which is created by man himself.

Environmental implications due to pollution are in various aspects. These produce serious problem for human beings to maintain its existence, protection, survival and for the improvement of general standard. The basic needs of human beings have disturbed natural resources and finally led to a situation which has threatened to be disastrous.

In the recent years everyone has started thinking over the problem of over-population and its consequences, which is primarily concerned with the environmental pollution and every effort should be made to focus public attention to save mankind from self destruction and steps should be taken at national and international levels so that the consequences may not become worse.

The ecological state of biosphere is becoming more and more dis-balanced day by day due to technical and industrial advancements as well as population explosion. Vast changes are taking place in the environment due to interaction between human society and environment itself. Man is exploiting the natural resources for its own interest and many such instances are there as clearly indicate that man has disturbed the natural balance for the sake of small benefits and has changed the environment of many places to such an extent that they are not fit for inhabitation by living beings.

The environmental science is concerned with the study of all the systems of air, land, water, energy and life that surround us. Environmental problems are so diverse and diffused that virtually every activity of civilization interacts with the environment. The addition of extraneous materials or energy in a particular environment in concentrations greater than the normal renders the environment partially or wholly un-favourable for human life.

This is referred to as environmental pollution. “Environmental pollution is the un-favourable alteration of our surrounding, wholly or largely as by-products of man’s action through direct or indirect effects of changes in energy patterns, radiation levels, chemical and physical constitutions and abundance of organisms”. These changes may affect man directly or through his supplies, of water and agricultural and other biological products, his physical objects or possessions, or his opportunities for recreation and appreciation in nature—from U.S. Products Science Advisory Committee, Environmental Pollution Panel (1965)

Pollution and contamination are two terms sometimes used interchangeably. Contamination is the presence of harmful substances or organisms that may cause diseases or discomfort to human beings. Polluted material need not necessarily be contaminated. Dependent as he is on air, water and food from environment, man is the main culprit in polluting these natural resources to the point of no return.

The natural sources of pollution are, no doubt, important on a global scale man generated pollutants may be more important in urban and industrial areas where the adverse effects of pollution are most severe. There is accumulating evidence that many types of pollutants can be distributed over the whole earth in relatively short period of time. Radioactive fallout from atmospheric nuclear explosion test is detectable throughout the world within a few days ‘or weeks; not even the polar regions are immune from fallout.

Comfort giving automobile’s are polluting the atmosphere with oxides of C, N, and other noxious gases. Coal, diesel oil and other fossil fuels are emitting suffocating SO2 and choking our lives. .

The law of conservation of mass or material equally applies to the pollutants and while one cannot destroy them, they may be changed from one state to another or from one compound to a another. The presence of small amount of pollutants may make profound influence on human health even when the level of air pollutants is so low that they cannot be detected except with special instruments. Some pollutants may harm living creatures exposed for long periods of time.

Hope it will help you.

Pollution

In simple terms, Pollution refers to any unwanted and hazardous substances that is harmful to environment. Today, even kids are aware about the term 'Pollution'. There are various factors due to which pollution spreads nowadays. All this pollution occurs just because of Human activities. Humans are only responsible for pollution and it's effects.

Our Earth is getting contaminated day by day due to increase in pollution. Pollution effects the quality of life and cause serious health problems. The effects of pollution on human beings and earth aren't naked sometimes, but they can cause very serious problems to living life.

The quality of Air has been decreased due to human activities like Industrial smokes, vehicles and release of CO2 in Air from last 20 - 30 years. As Co2 is important for Human life activities, it is even more harmful too. More CO2 to the human beings can cause serious breathing problems for not human beings but also all living creatures.

There are mainly 3 types of pollution's: Air Pollution, Water Pollution, Noise pollution.

Factors because of which air pollution occurs are Industries, Vehicles, Cigarettes, Natural activities like volcanic eruption etc. Air pollution cause problems related to Heart, Lungs and breathing. More Air pollution can even cause death of living organism.

Secondly, Contaminated waste water from industries, domestic water waste, release of toxic materials etc ; are the factors due to which Water pollution occurs. Water pollution is today's serious problem. The toxic water released from industries is very harmful for the nature ; But, this same water is consumed by living beings. Due to which, there are serious health problems due to this. Due to consumption of this same water, Human beings even have serious diseases.

Thirdly, Loudspeakers, Transportation, Poor urbanization, Industrialization, Social events are the factors reasonable for the sound pollution. Due to very large and unwanted sound produced, the environment and nature is disturbed and even humans may lead to hearing problems.

To reduce pollution and it's effects, we should start it from ourselves.

To reduce Air pollution:

We should use our Cycle for riding a small distance; it saves our money and natural resources are also saved.

We should use bus for travelling. It reduces our expenses and it's a huge advantage to save natural resources like Fuel.

Industrial and residential areas should be out of the city such that, the smoke released from them should not affect the citizens.

To reduce water pollution:

Industries should save the waste water near them and by applying chemicals on it, they should convert that water into usable water.
