Our earth is a paradise if we
live on it in a sensible way; otherwise it is the other name of hell.
Unfortunately, at present, man is misusing the resources of the earth which can
spell a doom for his own existence. Air, soil, water and space all are getting
polluted. It is high time that man gives attention to the hazard of pollution of
all kinds. Otherwise, there may be not only wide-spread epidemics, but even his
existence on this planet may be in danger. Humanity depends upon the environment
of earth .For the development and betterment of human society pollution free
environment is necessary .Environmental changes plays a vital role in security
of human beings, social relations and in completion of human needs.Air pollution
is taking place because of mindless felling down of trees and poisonous
emissions from chimneys of factories and automobiles. Excessive use of
insecticides and pesticides is causing soil pollution. Poisonous elements are
finding their way to the food- grains and milk.
Water channels like rivers and canals are getting polluted due to the release of
highly deleterious effluents into them by the industrial units. Even sea water
is getting polluted. Tons of debris from hurtling space-ships is polluting the
space. Experimental nuclear explosions and leakages from nuclear plants also
cause atmospheric pollution.
Quite another type of pollution is the noise pollution. It is caused by
loud-speakers, factory buzzers, vehicular horns, high pitch of T. V. sets and
radios and noises in streets and markets. Noise pollution can cause great injury
to our delicate nerves. In fact, all kinds of pollution are harmful to man in
more than one ways.
Today the situation is that, that at global and regional levels many evidences
are available which tells us that global warming is actually the cause of
increase in temperature. The process of melting of glaciers, average rise in the
sea level, and shortage of water decline in the fertility of land, shortage of
food is due to environmental changes. Unusual waves of summer and winter,
tornadoes, floods are increasing and in future these effects will gradually
increase .The situation is so devastating that according to research 2 million
people dies due to internal and external pollution. Ozone layer which protects
the earth from ultra violet rays is being damaged badly and availability of pure
drinking water is gradually decreasing. Water pollution is the greatest cause of
death in world today; if the shortage of pure drinking water continues at this
rate then in 2025 1.8 billion people would be living in those areas or countries
where water will almost disappear whereas two-third of the population would be
facing shortage of water. Therefore we must take some steps to finish pollution
and at least take a step forward in reducing these effects which will be better
for people of our country.
