Our environment means the surrounding of our house where we live, the surrounding of our village where we live or the surrounding of our town or city where we live.
Environmental pollution is the biggest menace to the human race on this planet today. It means adding impurity to environment. The environment consists of earth, water, air, plants and animals. If we pollute them, then the existence of man and nature will be hampered.
Effects of Pollution
Effects of pollution on the climate ar/dangeror.s – though so slow and gradual as to be beyond easy recognition.” Air pollution results in the steady rise in the amount of carbon dioxide and dust particles in the atmosphere. Increase in carbon dioxide raises the earth’s temperature while increase in the dust particles decreases it. An increase either way means change away from the mean. According to an estimate dust particles can absorb 3 to 4 per cent of the sun’s radiation, and thus lower the earth’s temperature by about 0’4°C.
Environmental pullution is no longer only a fashionable catch-Word. It has infact become one of the most formidable threats to mankind. With the growing development of technology and growing world population, pollution is no longer restricted to a certain number of industrial countries but affects the ecological system of vtiit areas. As we become increasingly aware of our limited natural roiources, the protection and preservation of nature becomes a world-wide concern.
