Air pollution

Pollution indicates humiliations. It is world-wide worry currently. Emitting carbon monoxide gases vehicles pollute our city lives seriously. Besides, burning of trash and indiscriminate discharge of human waste in open air is also the cause of serious air pollution. Serious air pollution occurs in industrial areas where the workers become sick. Sometimes, the sickness is so serious that it cannot be cured. To prevent such air pollution,we should be determined and take positive steps to make our air clean. Steps must be taken to control the haphazard growth of industries. We should shift the mills and factories away from the locality or residential areas. Excessive smoke should be banned from playing on the streets. Lead – free petrol should be used in vehicles to minimize air pollution, because the WHO and the UNO environmental section indicate Dhaka as the most polluted city in the world. The best way to stop pollution is to plant trees and take care of them. The wildlife must be preserved and the mass cutting down of trees must be prevented.
