Sir: Presently, we are facing one of the most horrible ecological crises of the time i.e pollution. The pollution is an undesirable change in the physical, chemical or biological characteristics of air, soil, and water which can harmfully affect human life. The environment of the world is gradually going to be polluted. The pollution pace has been increased considerably after the industrial revolution of the previous century. However, there are some types of pollution like air pollution, water pollution and land pollution. In addition to these, there are other kinds of non-material pollution too as like radiation pollution, noise pollution and thermal pollution.
