Nature,
air, water, land and all other things around us in which we live are called
environment. Any unexpected and abnormal change in chemical, physical and
biological characteristics in environment is called the environmental
pollution. Now our environment is getting polluted every moment in many ways. In
major cities and towns motor vehicles, mills and factories are creating fume
and smoke and they pollute air. Man makes fires to cook food, to make bricks,
to melt tar for road construction and to do many other things. Fires create
smoke and pollute the air. Railway engines and powerhouses create smoke by
burning coal and oil and this smoke pollutes the air. Water, another vital
element of the environment like air, is also polluted in many ways. Man pollutes
water by throwing waste into it. Chemicals, fertilizers’ and insecticides get
mixed with water in rivers, canals and ponds, and thus pollute water. Mills and
factories also throw their poisonous chemicals and waste products into rivers,
canals and seas and water is polluted.
Moreover,
water vehicles, unsafe drains and unsanitary latrines are also responsible for
water pollution. These days many rivers and lakes are getting filthy. Forests
and trees are being cut down on a large scale. So, the ecosystem of the
environment is now in great danger. The noise of motor vehicles, mills and factories,
airplanes, domestic appliances, radios, cassette players, CDs, televisions etc
pollutes sound and this polluted sound affects our hearing. The government must
take effective steps to prevent the pollution. People of all classes should
come forward to control this environmental pollution because it is necessary for
our own existence.
