What causes the pollution of our atmosphere/ motor vehicles of all kinds,including cars and trucks give off carbon monoxide, hydrocarbons, oxides ofnitrogen. Industry generates hydrocarbons, nitrogen oxides, Sulphur oxides, dust,fly ash and all kinds of odors. More dust particles are produced by grinding andblasting of rocks, and by construction work, spraying of insecticides and burning ofgases in agriculture increase the poisonous gases and particles in the air.In what ways do people in your community increase pollution?Do you live near a factory? If you do, living near a factory can be hazardous.House and buildings can be blackened by the smoke from factories. Metaldrainpipes, roofs and gates corrode. Rubber rots, lead-based paints on buildingspeel off. A factory may give off bad- smelling Sulphur wastes. But the more seriouseffects are those on human health. Thousands of people die every year frominhaling polluted air.On the average, you inhale 22,800 liters of air each day. Your lungs getabout 4560 liters of pure oxygen. You inhale a lot of air. But you also inhale anestimated 0.7 kilograms of pollutants per year in the form of particles of dirt.The poisonous gases in the air are also harmful to plants. They destroy thegreen coloring in plants. The leaves or plants dry up and rot. Spotty marks onleaves are produced by these pollutants in the air.We should stop polluting air. Air is hard to clean once it has been polluted.We also cannot control the air we breath. Prevent air pollution and you prolongyour life.We should also plant more trees and flowering plants. All forms ofvegetation convert carbon dioxide into oxygen, the gas we breath.
