With the rapid development of society and economy and the acceleration of urbanization, environmental problems have increasingly become the focus of global attention. Among them, the deterioration of air quality is particularly prominent, which not only affects people's health, but also has an irreversible impact on the ecological environment. Faced with this challenge, governments, enterprises and the public in various countries have begun to realize the importance of taking effective measures to improve air quality, thus opening the prelude to a new round of environmental protection actions-environmental protection movement starting from air treatment.

I. Background and current situation

In recent years, due to industrial emissions, automobile exhaust, construction dust and other factors, the concentration of PM2.5 in many cities has seriously exceeded the standard, resulting in frequent "smog" weather, which has brought great inconvenience to people's lives. Especially in winter, some northern cities suffer more. Long-term exposure to polluted air will increase the risk of respiratory diseases, such as asthma and chronic obstructive pulmonary disease, and may even lead to cardiovascular diseases. Therefore, how to effectively control the emission of air pollutants and improve air quality has become an urgent problem to be solved.

Second, the policy response

In view of the severe air pollution situation, the Chinese government responded quickly and introduced a series of policies and measures. For example, since its implementation in 2013, the Air Pollution Prevention Action Plan (referred to as "Atmosphere Ten") has achieved remarkable results in reducing coal consumption, promoting the use of clean energy, and strengthening the control of motor vehicle exhaust. In addition, local governments have also formulated detailed implementation rules for localization, strengthened law enforcement, and ensured that all measures take root.

Third, technological innovation and practice

In addition to policy support, technological innovation also plays a key role. Many enterprises and scientific research institutions have invested a lot of resources to develop new environmental protection technologies, such as high-efficiency dust removal equipment, low-sulfur fuel substitutes and electric vehicles, in order to reduce pollutant emissions from the source. At the same time, through big data analysis, artificial intelligence prediction and other means to optimize urban management, achieve accurate pollution control and improve governance efficiency.

Fourth, the participation of the whole people

Improving air quality is not only the responsibility of the government, but also the participation of the whole society. More and more people begin to pay attention to the choice of green lifestyle, such as cycling to work and reducing the use of disposable plastic products. Schools and social organizations also actively carry out publicity and education activities to enhance citizens' awareness of environmental protection and form a good social trend.

Air pollution control is an important task facing China and even the whole world in the new era. It is not only about technological progress or the perfection of laws and regulations, but also a profound social change. Only when everyone regards protecting the environment as their responsibility can we truly welcome the days of blue sky and white clouds. Let's work together to leave a better home for future generations.
