Clean air is a complex issue involving many aspects, including reducing pollution sources, improving air quality, using clean energy, etc. Here are some suggestions and methods to help improve air quality:

Reduce traffic pollution: Use public transportation as much as possible and reduce the use of private cars. Buying an electric car or a low-emission car is also a good option.

Use clean energy: Use solar panels or wind power in your home to reduce your dependence on fossil fuels.

Industrial Emission Control: Industrial production is one of the major sources of air pollution. Strengthen supervision of industrial emissions to ensure they meet environmental standards.

Indoor air quality management: maintain indoor air circulation, use air purifiers, grow indoor plants, etc.

Waste sorting and recycling: Correct waste sorting can reduce air pollution by reducing waste incineration or landfilling.

Afforestation: Plants absorb carbon dioxide and release oxygen, helping to improve air quality.

Government policies and regulations: Comply with local and national environmental protection regulations and policies, and support and participate in environmental protection activities.

Education and awareness-raising: Understand the causes and effects of air pollution and how to take steps to reduce it.

Scientific research and development: Continue to support the research and development of environmentally friendly technologies, such as clean energy technology, high-efficiency filtration technology, etc.

International cooperation: Cooperate with other countries and international organizations to jointly address global air pollution problems.

Through the above methods, we can work together to improve air quality and create a cleaner and healthier living environment
