The garbage emitting foul smell, the decaying plants and animals also cause air pollution. Hence the doctors advise the patients having lungs trouble to settle in some rural places because the air of villages is pure and free from population.
Then comes sound pollution. The harsh sounds of buses, its, mopeds etc. affect our power of hearing and causes fart trouble. It has been reported that there are two villages named Biraspalli and Devadas Palli near Dum Dum airport m Calcutta where a large number of people have lost their power of hearing. This is because of the frequent sounds of planes coming in and going out of Dum Dum Airport. The evils of sound pollution can be imagined from this example.
The water of rivers and seas is being constantly polluted all over the world by various dangerous chemical and biological wastes. Mills and factories discharge very harmful waste waters into many rivers and sea. The water of the Ganges flowing by the side of both Varanashi and Calcutta is extremely polluted and contains all sorts of dangerous bacteria. It is really very strange and laughable that large number of the Indians regard this water as holy. They even drink this water for salvation. There is no doubt that the fish that grow in such waters are poisonous too.
Reckless application of chemical fertilizers, insecticides and pesticides pollutes the soil. Vegetables and fruits are quite injurious today, because they contain the poison of insecticides and pesticides.
If the air we breathe, the water we drink and the soil which produces our crops, vegetables and fruits, all become more and more impure, then our chances of good health and longevity will be very less and less. Environment pollution is a serious menace to our existence. Realising the danger, we must plant trees in large number to absorb impure air. Impure water from industries can be sent back for purification and then it can be used for irrigation purpose. Our government is well aware of the fact
