Pollution

Environmental pollution is the biggest menace to the human race on this planet today. It means adding impurity to environment. The environment consists of earth, water, air, plants and animals. If we pollute them, then the existence of man and nature will be hampered.
It is true that trees are being cut down rapidly. Our earth is becoming warmer. If pollution continues, the day is not far when our earth will be a boiling pan and become a desert. Or it will be covered with sea water causing destruction of mankind.
Pure air is always needed for inhaling. If we take pure air, our health improves. On the other hand impure air causes diseases and impairs our health and causes our death. Smoke pollutes the air. It is the root of air pollution. The smoke which is discharged from industries, automobiles and kitchens is the mixture of carbon monoxide, carbon dioxide, methane etc. These are all poisonous gases. These cause lung-cancer, tuberculosis etc. which take a heavy toll of life. The glaring incident is the Bhopal gas leak in December 1984. Thousands of the residents of Bhopal died due to lungs problem which was caused by methylamine gas from the Union Carbide Plant.
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.
