Environmental Pollution: A
cause of health / hazard
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, fertilisers 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,
aeroplanes, domestic applia
nces,
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 poll
ution
because it is necessary for our own existence.
04.Satellite
TV Channels: A source of cultural interaction.
Satellite
TV is one of the greatest achievements of modern science. Now it is regarded as
the medium of information, entertainment, telecast,education and many others.
It can telecast any live programme from the remotest part of the world.
Satellite TV can display many programmes at a time. With the help of satellite,
world has turned into a global village. Now we can watch Australian, British or
American TV programmes sitting before our own TV set. Satellite TV has added a
new dimension in our oriented life providing many programmes through different
channels. It‘s not only a good medium of recreation but also a source
educational knowledge. Different channels telecast various educative dramas,
movies, sports, cultural functions, news and articles. So we can easily collect
educative information of agriculture, science and technology, politics,
education, business, invention etc. Satellite TV helps us widespread the sight
and outlook of the society. Coming to contact with the western societies, we
are getting the opportunities to
enrich
our society and ourselves. But on the other hand, many people especially young
generations are getting hampered and we all are now forgetting our own customs,
traditions, music and culture. Very often obscene pictures and vulgar movies
and programmes are shown in various satellite channels. Young generations are
becoming more and more addicted to them. Moreover, most of us want to follow
the dress-pattern, hairstyle, behaviour, music and nudity of the westerns. This
mentality is leading our young generations to moral degradation. So, we all
should be conscious of that.
