Write a paragraph, Essay or Composition about "Air Pollution".
Air pollution means the ways in which the air is polluted. Air is the most important element of the human environment. Man can not live a single moment without air. But we do not think that it is we who pollute this most vital element. Clean air is essential for life. Air is polluted in many ways. For example, smoke pollutes the 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 the air.
The another example is that railway engines, powerhouses, mills, and factories use coal and oil. Moreover, buses trucks and cars use 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 plying the street every day. Sometimes men in a big industrial area become so sick by inhaling polluted air that they cannot be cured. So proper measures and steps should be taken to prevent air pollution.
