Social and environmental problems have increasingly become the focus of global attention, among which air quality is one of the key factors directly related to human health and quality of life. With the acceleration of industrialization and urbanization, the problem of air pollution has become more and more serious, which not only affects people's quality of life, but also has an irreversible impact on the ecosystem. Therefore, it is of great significance to establish and improve a scientific and effective air control system for promoting sustainable development.

First, the present situation and harm of air pollution

In recent years, due to automobile exhaust emissions, industrial production waste gas and construction dust, the concentration of harmful substances such as PM2.5 and sulfur dioxide in the air has continued to rise. Long-term exposure to polluted environment will increase the risk of respiratory diseases and cardiovascular diseases, and may induce various chronic diseases such as cancer. In addition, severe smog weather will also interfere with traffic and cause economic losses.

Second, the importance of air governance

Facing the severe air pollution situation, it is particularly urgent to take effective measures to improve air quality. Good air quality is an important part of people's happy life, and it is also one of the standards to measure the level of ecological civilization construction in a country or region. Strengthening air quality management can not only protect public health, but also promote the optimization and upgrading of economic structure and realize green and low-carbon transformation.

Third, build a sound air control system

1. Legislative guarantee: establish and improve relevant laws and regulations, clarify the responsibilities and obligations of the government, enterprises and individuals, and provide a solid legal basis for environmental protection.

2. Technological innovation: encourage and support the research and application of clean energy technologies, promote the use of new energy vehicles, and reduce the pollutant emissions caused by traditional fossil energy consumption.

3. Public participation: improve citizens' awareness of environmental protection and advocate a green lifestyle, such as walking and cycling instead of driving; Participate in afforestation and other activities to jointly safeguard a beautiful home.

4. International cooperation: In view of the characteristics of cross-border transmission of air pollution, it is necessary for all countries to strengthen exchanges and cooperation and form joint efforts in information sharing and technology transfer.

5. Monitoring and early warning: Establish a comprehensive urban air quality monitoring network, release the air quality index (AQI) in time, and guide people to arrange their daily activities reasonably to avoid being in a highly polluted environment for a long time.

In a word, air pollution control is a complex and arduous task, which requires the joint efforts of the government, enterprises and all sectors of society. Only when everyone internalizes the idea of "Lucid waters and lush mountains are invaluable assets" and externalizes it in deeds can we truly usher in a bright future with blue sky and white clouds.
