With the acceleration of society, industrialization and urbanization, air quality has attracted more and more attention. Air pollution not only affects people's health, but also causes serious damage to the ecological environment. Therefore, taking effective measures to improve air quality has become one of the important tasks to be solved urgently. This paper will discuss several environmental protection measures that can be implemented in air purification activities in order to contribute to building a more livable and healthy environment.

1. Promote green travel modes.

Reducing automobile exhaust emissions is one of the effective ways to improve air quality. Encouraging the public to use low-carbon travel modes such as public transport, cycling or walking can not only reduce pollutant emissions, but also promote health. The government can support this change by increasing bus routes and optimizing the layout of bicycle lanes.

2. Strengthen industrial pollution control

Industrial enterprises are one of the main sources of air pollutants. Strengthen the supervision of key industries and strictly implement the national standards and regulations on waste gas emission; At the same time, enterprises are encouraged to adopt advanced cleaner production technologies to achieve emission reduction at the source. In addition, units that violate the regulations should be severely punished according to law to form a deterrent effect.

3. Planting trees and greening cities

Trees can absorb carbon dioxide and release oxygen, which has good air purification function. By carrying out large-scale afforestation projects and adding public spaces such as parks and green spaces in the city, it can not only beautify the city appearance, but also help to improve the air quality level in the region.

4. Popularize environmental awareness education

It is very important to raise the awareness of individual citizens and all walks of life on the importance of environmental protection. Schools and communities should hold lectures and publicity activities on relevant knowledge on a regular basis, so as to guide everyone to start from daily trivial matters, such as saving electricity and reducing the use of disposable plastic products, and jointly participate in the action of protecting the blue sky and white clouds.

5. Develop new energy industry

Actively support the development of renewable energy such as wind energy and solar energy, and gradually replace traditional fossil energy as the main power source. This is not only conducive to alleviating the problem of a large number of greenhouse gas emissions caused by burning coal and oil, but also an inevitable choice to achieve sustainable economic and social development.

To sum up, in the face of severe air pollution challenges, we need to start from many aspects and make comprehensive policies. Only when everyone realizes their responsibilities and puts them into practice can we truly usher in a fresh and beautiful new world.
