Ecological Crises: 

The natural atmosphere which man has inherited from the past, with healthy and fresh air, shielding from excessive radiation of the sun, has been deteriorating both under the impact of increased population and industrialization. Factories pump millions of tons of dust and smoke into the air, cars and buses spread fumes and stir up dust from the roads into  the air, and sprays used to kill agricultural pests all combine to change the idealpicture. The pollution of the air has become a matter of great concern because it continues to increase as "civilization"  spreads. Near big cities and heavily  industrialized areas;the  situation has become so bad that the birds have become rare, and the air is not fit for breathing. Rural areas are beginning  to be affected. Society will have to move towards strict pollution control, and protection of the atmosphere as it is a great and irreplaceable resource for living.
