Now write a paragraph on Air Pollution.
Air, water, soil, tree, animal make up our environment. Here the air is one of the most important elements of our environment. But the air is being polluted so severely that this problem has become a global concern at present. There are many ways to pollute the air. Especially it is more acute in urban areas for playing unlimited vehicles and stabilizing a lot of mills and factories which emit carbon monoxide gases and smokes that pollute the air. Besides, man makes fires to cook food, to make brick, burns refuse and wood melts pitch for road construction, and so on. All these things produce heavy smoke and this smoke pollutes the air. By inhaling polluted air we are falling victim to bronchitis and another respiratory disease. So, air pollution should be prevented by raising public awareness. Lead-free petrol should be used in vehicles. Laws should be passed to prevent factories for emitted carbon monoxide gases. We may increase afforestation to prevent air pollution. By preventing air pollution we can be healthier and happier lives.
