Measures to control Air Pollution

Trees make the biggest contribution in reducing air pollution. Therefore , trees should be planted extensively on the banks of roads, canal tracks and railway lines and other vacant lands.
Green belts should be used near industrial areas in which such trees should be planted which have the ability to absorb the smoke of chimneys and the deadly gases released along with the smoke of industrial companies, such as Peepal and Banyan trees are considered suitable for this. .
Industrial factories and the government should make efforts to keep the amount of harmful gases spreading in the atmosphere as per the prescribed standards, for which air purification devices must be installed in all industrial companies.
The height of chimneys should be sufficient as per the standards so that there is minimum pollution in the surrounding area.
By installing catalytic converter in petrol cars, air pollution can be reduced to a great extent. And the use of petrol and diesel cars should be minimal, battery and CNG cars do not cause pollution. Use them as much as possible.
By reducing the use of fossil fuels ( petroleum , coal), which pollute the atmosphere, alternatives like solar energy, wind energy can be helpful in saving the environment.
