In the 21st century, with the rapid development of industrialization and urbanization, air pollution has become one of the major environmental problems facing the world. Haze, PM2.5 and other pollutants not only affect people's health, but also pose a threat to the ecological balance of the earth. Facing this challenge, more and more people begin to realize the importance of environmental protection, and take improving air quality as one of the important goals to realize green life. The purpose of this paper is to explore how the desire of air purification becomes the driving force to promote the ideal of environmental protection.

Present situation and challenges of air quality

　　In recent years, the air quality in many cities has reached the lowest point in history due to automobile exhaust, industrial production waste gas and construction dust. Especially in winter, severe smog weather frequently occurs in the northern region, which seriously affects people's daily life quality and health. Long-term exposure to polluted air will increase the risk of respiratory diseases and cardiovascular diseases.

Public awareness awakening

With the improvement of people's pursuit of a healthy lifestyle, the public's demand for good air quality is growing. The discussion on the topics of "blue sky and white clouds" and "fresh air" on social media has not diminished, reflecting that people have strong expectations for improving air quality. At the same time, more and more non-governmental organizations and social groups have joined in the actions of promoting environmental protection knowledge and advocating low-carbon life, and worked together to create a cleaner and more beautiful home.

Science and technology help purify the air

The progress of science and technology has made it possible to solve the air pollution problem. For example, the development of new energy vehicles has reduced the exhaust emissions brought by traditional fuel vehicles; The application of intelligent transportation system improves the road traffic efficiency and reduces the pollution caused by congestion; In addition, there are a variety of air purifier products entering the home to help filter indoor and outdoor harmful substances and improve the quality of the living environment.

Policy support and international cooperation

Governments all over the world have gradually realized the importance of controlling air pollution and introduced a series of policies and measures. For example, the Air Pollution Prevention Action Plan implemented in China has effectively controlled pollutant emissions in some areas by limiting the expansion of highly polluting industries and promoting the use of clean energy. At the same time, strengthen cooperation and exchanges at the international level, share technical experience, and make joint efforts to deal with cross-border environmental pollution problems.

In a word, "Environmental Ideal of Air Purification Desire" is not only the aspiration of every citizen, but also the common responsibility of all mankind. Only when the whole society of Qi Xin works together and starts from itself can we gradually realize this beautiful vision and restore the vitality and vigor of our planet.
