Air pollution means the ways in which the air is polluted. air is the most important element f human  environment . Man cannot live a single moment without air. But we do not think that it is we who pollute e this most valuable element. Clean air is important for life. Air is polluted in many ways. For example smoke pollutes air. Man makes fires to cook his food, to make bricks burns refuse, melts pitch for road construction and burns wood. All these things produce heavy smoke and this smoke pollutes air. The anther example is that railway engines, power houses, mills and factories use coal and oil. Moreover, buses trucks and car s uses petrol and diesel oil. Again all these things create smoke and cause air pollution. Furthermore, the most serious air pollution occurs in big industrial areas where there are many mills and factories. Again serious air pollution also occurs in big cities where there are many buses, trucks and cars play in the street every day. Sometimes men in the big industrial area become so sick by inhaling polluted air, that they cannot be cured. So, proper steps should be taken to stop air pollution. We all should be conscious about this air pollution.
