Pollution
is the damage caused to the environment by harmful substances or waste.
Pollution is our enemy number one today. Modern civilization and material progress
have resulted in pollution everywhere-in the atmosphere, on land, in the seas
and in the rivers.
Our air is polluted by smoke, gases and chemicals
emitted by vehicles and factories. Besides this, there is noise pollution in
big cities caused by vehicles, machines, loudspeakers and crackers. Pollution
poisons the air and harms the ozone layer of the earth that protects us from
the radiation of the sun. If the ozone layer is destroyed, mankind will perish.
Nuclear radiation also pollutes the air causing terrible health hazards.
Tonnes
of industrial and chemical waste are thoughtlessly dumped into our rivers,
lakes, and seas and they kill fish and other marine life. Unplanned growth of
cities brings about more and more slums, where dirt, disease and death breed.
We
must take immediate and effective steps to fight pollution. We must reduce
vehicular and factory smoke. We must stop the dumping of chemical wastes into
our rivers, lakes and seas. We must frow more trees, protect our forests, and
have more gardens and open spaces. The sooner effective steps are taken the
better it will be for mankind.
