Any undesirable physical, chemical or biological change caused to land, water, air and other natural resources is termed as environmental pollution. These pollutions make life very difficult. Though there are various causes for pollution, man himself is a major cause. Over-pollution is the chief cause. Air pollution is due to industrial and automobile exhaust. These contain carbon dioxide, sulphur dioxide and oxides of nitrogen. They cause breathing trouble and even cancer. Plants are unable to synthesis food. The protective ozone layer is affected thereby, exposing us to the ill effects of radioactive rays. Accumulation of rubbish, polythene and plastic containers, glass and porcelain, result in land pollution. They cause various diseases. The letting in of domestic sewage waste, industrial waste and tannery effluents, pollute drinking water. The use of excess of chemical fertilizers, insecticides, pesticides and DDT, pollute both land and water. They lead to many deadly, contagious diseases. Oil leaks in the oceans affect marine life. They endanger many marine species. Gas leakage, leakage of nuclear reactors also poses several threats to us. The latest is the leak of cyanide from a gold mining company in to the blue Danube. More than 80% of the marine species is dead. The river has turned grey. Unless suitable steps are taken to check pollution, mankind will be destroyed along with other organisms.
