Pollution is a word that we are all aware of these days. What does it
mean exactly? If you look up "pollution" in the dictionary you will find
something like - "to destroy purity of; to contaminate, especially with
man-made waste". Yes the environment, i.e. our surroundings, the place
we live, is being made unclean by our own activities. The pollutants we
produce not only affect our own lives but also those of other living
things, the plants and animals that we share our environment with. All
living things depend upon the non-living parts of the environment to
survive - the land, the air and the water, and it is these 3 parts which
are affected by pollution...

POLLUTION :
we know very well that we can live for some time without food, but we cannot live even for a few seconds without air. So, air is the first thing that we need to live. on the other hand, we all are aware that our environment is not what it used to be. It's quality and purity is falling day by day.
How do you feel when you sit in a place where there is a lot of smoke ? you would feel uncomfortable . you feel difficulty in breathing. sometimes even tears may come out of your eyes. while on hilly areas and on sea shores the air is comparitively pure and fresh.
Also, If you compare the life of villages and that of cities you feel very well the difference in the quality of air. This is due to the fact that the air in mountains and villages is usually free from pollutants like smoke. The number of vehicles , industries and people is less in these areas.
our environment is under a Great threat because most of the activities of man practically add to the pollution of the air around us.
pollution is the contamination of our Physical environment which consists of air, water, and soil. The Substances which contaminate the environment are called pollutants.
→ We ourselves can also contribute to prevent the pollution and improve our environment :-
♣ We can plant more and more trees and nurture the ones already present in the neighborhood. because they are the nature's lungs and remove Harmful gases.
♣ We should not use bags made from plastics, because they are non- biodegradable. we should use only cloth and jute bags.
♣ We should save electricity , In the long run, it will amount to burning of fossil fuels.
♣ use of CNG should be encouraged.
♣ Do not destroy Flora ( plants ) and Fauna (animals) , to maintain the proper ecological balance.
♣ pesticides like DDT should be used . many countries have banned the use of dangerous pesticides like DDT and have found ways of safe disposal of wastes.
