Environmental Pollution >>>>>>>>>

The act of releasing any solid, liquid or gaseous substance in such a large concentration that it tends to be injurious to environment and hazardous to the environmental components is termed as Environmental Pollution.

The environmental pollution is the price we are paying for modern civilization and material progress. It literally means making foul, filthy, and dirty. Environmental Pollution is our enemy numero uno today. There is an all-round pollution everywhere in the atmosphere, on the lands, and in the seas. The air around us is polluted by the smoke and various gases puffed out by vehicles and factories and by the tremendous use of modern chemicals.

Basically the environmental pollution is of three types;
1) Air Pollution
2) Water Pollution
3) Noise Pollution
Radiation pollution & Soil pollution are the other types of pollution which are picking up their pace in recent years. But out of all these Air pollution is the most hazardous. It is a serious problem in industrialized & congested cities. Heavy traffic and use of modern chemical fertilizers pollute the air and posses terrible health hazards. Pollutants like HF, H2S, and SO2 even if present in small amounts in air are dangerous and result in dreadful diseases like respiratory paralysis, bronchitis, fibrosis, cardiac and pulmonary disorders. The tragedy that occurred on Dec 3rd , 1984 due to leakage of Methyl isocynade affected lakhs of innoscent residents very badly. Among our cities which are dangerously polluted each day may be mentioned Kolkata, Mumbai, Chennai, New Delhi, and Ahmedabad. These are on the brink of total misfortune resulting from upsetting the balance between living beings and their surroundings. Water bodies like river and lakes are also the victims of environmental pollution. Huge industrial and chemical wastes are dumped into them from factories killing the flora and fauna. As a result the polluted water destroys agricultural products. It corrupts the soil and makes it useless.

Noise pollution is termed as a silent killer. In recent years, noise pollution has increased to a great extent. Generally hearing capacity of human beings is of 180 dB, but above 140 dB noise is undesirable by the recipient. Loud noise affects the human beings in many ways. Continuous exposure to loud noise may bring about a permanent loss of hearing. Heart beats of a person increase. Brain and lever of a person are also affected. A person may be disturbed emotionally. Plants are also affected due to loud noise. The rate of process of photosynthesis declines. Household appliances , loudly played radios & TV’s , vehicles and small industries add to increasing noise pollution. But of all pollutions noise pollution is the easiest one to control, but the people must be aware of it. So a great environmentalist says that “ Let silence whisper peace into your ears “ . Like noise pollution , Radiation pollution is also dangerous . Nuclear activities and nuclear tests lead to radiation pollution. The radioactive substances and their by –products remain in the atmosphere for a long period of time and pollute the air . These pollutants destroy the human chromosomes and genes and bring about permanent hereditary disorders. So radiation pollution is very dangerous.

Environmental pollution is the reason which helps in the poisoning of air and harms the ozone layer of the earth , which protects us from the harmful ultraviolet radiations of the sun. If the ozone layer is destroyed mankind will perish , from the harmful radiations. So we must fight this evil with all our might.

But although , environmental pollution seems to be dangerous and difficult to control it is in our own hands to fight this evil. So we must take effective and efficient steps to control it. The vehicular and factory smoke should be reduced by modern equipments like gas absorbers , wet collectors , bag filters , oxygen furnaces etc. Some efficient method of disposing of garbage which is pilling up at an alarming rate in many parts of the cities should be developed . The dumping of chemical wastes of factories into the rivers and seas should be stopped. We should plant more trees , protect forests and bring about more gardens and open spaces . This is because trees act as bio-monitor for the problem of environmental pollution . Hence , it is said that

The enemy’s enemy is a friend , pollution is our enemy , trees are our friend which eliminate it.

Many institutions and organizations in our country and abroad should propagate important values relating to environmental pollution . Recycling as a means of controlling environmental pollution should be brought into use on a large scale. Interestingly ways of recycling cans, newspapers, glass bottles, rubber and other articles of daily use should be found out.

Due to all these sorts of pollution taking place in the entire world mankind is on the verge of extinction. So the sooner we take effective steps against this act , the better it is for the welfare of mankind.
