Air pollution
The problem of pollution is engaging the attention of the
sensible people in the developed as –well – as the developing countries. What
do we mean by pollution? It means contaminating the elements of air, water and
earth. We are polluting the air that we breathe.The agents of air pollution are
the chimney smokers and the fumes from cars and trucks . In winter there is
thick smoke all over the city.
As a result the people don’t get enough oxygen. They develop
bronchial problem or breathing trouble. Delhi alone has millions of vehicles
which burn petrol or diesel. Then there are thermal power plants and factories
which use coal. There is hardly any green cover left on the ridge. Trees have
been felled and the public parks have turned into slums. If we don’t check air
pollution the day is not far when we shall have to carry oxygen cylinders to
keep us alive.
