What are the reasons for this catastrophic state at present? The polluted air from major industries, large number of vehicles using petrol and diesel vehicles on the road, polluted water in the rivers and water streams and crops and vegetables raised from polluted fields have caused  a  havoc in the environment and its habitants- man, animals , birds and, monuments.
