What are the steps to control air pollution?

1. Reduce the burning of fossil fuels: Burning of fossil fuels such as coal, oil and natural gas produces large amounts of carbon dioxide, sulfur dioxide and nitrogen oxides, which adds to air pollution. Replacing these fuels with cleaner energy sources such as renewable energy (solar, wind, hydropower) can help reduce air pollution.

2. Replace old vehicles and engines with cleaner technologies: Older vehicles and engines emit more amounts of pollutants into the air. Replacing them with newer, cleaner engines can help reduce air pollution.

3. Increase efficiency of industrial processes: Industries can reduce air pollution by increasing the efficiency of their processes. This means that they can use fewer resources for the same output, which will reduce the amount of pollutants released into the atmosphere.

4. Improve urban planning: Urban areas with congested roads and dense buildings increase the amount of air pollution in the area. Improving urban planning in cities and towns can help reduce air pollution by better circulating air in the area.

5. Plant trees and vegetation: Trees and other vegetation absorb pollutants from the air and produce oxygen. Increasing the amount of trees and vegetation in cities and towns can help reduce air pollution.
