Question

Rapid progress in science and technology in the last fifty years has revolutionized our lives. Tremendous achievements have been made in the fields of telecommunications, space travel, medicine, engineering and agriculture. But it is now quite clear that all this progress has come at a heavy price. We have indiscriminately
used up our natural resources and caused terrible damage to our environment by adding to the pollution levels.
These levels are much higher in urban areas because of the greater presence of technology than in rural areas.
There are mainly three kinds of pollution - air, noise and water - that affect the lives of people living in a city,
The poisonous fumes emitted by the exhaust pipes of cars and buses constantly add to the level of carbon
dioxide in the air. It is this poisonous air, devoid of proper content of oxygen, that city dwellers breathe every
day. Small children lose their immunity and fall prey to dreaded diseases like asthma and bronchitis,
Noise pollution has also acquired grave proportions in cities. Noise pollution is mainly the result of lack of
awareness among people. Thoughtless use of loudspeakers and homs and the blaring sound of music played
inside homes and publicly during festivals all increase noise pollution. Recent studies have revealed that high
decibels of sounds can damage the central nervous system of human beings. This may lead to diseases like
high blood pressure,
palpitation and constant headaches.
The third kind of pollution is also the result of our carelessness and selfish attitude. We have, ourselves,
contaminated the very sources of water that we use. The chemical effluent from factories, the sewage from
the cities, the waste water from households are all dumped into the rivers that supply water for drinking and
bathing. As a consequence, not only does the water become unfit for drinking for both man and animal, but it
is no longer capable of supporting underwater life. If we analyse the causes of all kinds of pollution mentioned
above, we'll find that we have no one to blame but ourselves for the degradation of our environment. Each
individual can easily bring this situation mder control with a little awareness and a little effort. We should
consciously keep pollution of our vehicles under control, pool vehicles, use public transport, clean up our
rivers and cut down on noise. On the other hand we can add to the city's green cover by planting more trees.
Only if these steps are taken immediately we can hope to save ourselves from impending destruction.
