How to control air pollution?

1. Establish clean air standards: Governments can develop and enforce laws limiting the amount of pollutants allowed in the air. This ensures that companies and individuals do not exceed these limits.

2. Clean up existing sources of air pollution: Governments can invest in technologies to reduce air pollution from existing sources, such as factories and vehicles. Companies can also play a role in this by investing in cleaner production methods.

3. Increase public awareness: Governments and private organizations can promote public awareness campaigns to educate people on the importance of air quality and how to help improve it.

4. Use cleaner energy sources: Governments can encourage the use of cleaner energy sources, such as renewable energy sources, instead of fossil fuels which produce more pollutants.

5. Implement green technology: Governments can invest in research and development of new green technologies to reduce air pollution. This will lead to more efficient and cleaner ways of producing energy and goods.
