In the early 21st century, with the rapid development of economy and the acceleration of urbanization, the problem of environmental pollution has become increasingly prominent, among which air pollution has become one of the major global environmental challenges. As the largest developing country in the world, China is experiencing unprecedented industrialization and urbanization, and is also facing severe air quality problems. However, it is under this gray sky that the prelude to the "blue sky defense war" is slowly opened, which is not only related to the country's development strategy, but also a journey of environmental awareness with the participation of the whole people.

First, from consciousness to action: the promotion of public awareness of environmental protection

In the past, people often put economic development in the first place and paid insufficient attention to environmental protection. However, smog weather is frequent and respiratory diseases are increasing, and more and more people are beginning to pay attention to the relationship between their health and their living environment. On social media, technical terms such as "PM2.5" and "AQI (Air Quality Index)" have gradually become popular and become indispensable topics in daily communication. The government strengthens publicity and education through various channels and encourages all sectors of society to actively participate in practical actions to improve air quality.

Second, pay equal attention to policy guidance and scientific and technological innovation

Facing the complicated problem of air pollution, China government has adopted a multi-pronged strategy. On the one hand, a series of laws and regulations have been promulgated, such as the Law on the Prevention and Control of Air Pollution and the Three-year Action Plan to Win the Blue Sky Defence War, to clarify the objectives and refine the measures to provide legal protection for the governance work; On the other hand, increase investment in scientific research, support the research and development of green and low-carbon technologies, promote the optimization and upgrading of industrial structure, and reduce pollutant emissions. In addition, it also actively introduces foreign advanced experience and technology to promote exchanges and cooperation at home and abroad.

Third, multi-party efforts to create a better future

Improving air quality is a long-term and arduous task, which requires the joint efforts of the government, enterprises and every citizen. Enterprises and individuals should take the initiative to assume social responsibilities and practice the lifestyle of energy conservation and emission reduction; Social organizations can play a bridge role, organize voluntary service activities and enhance social cohesion. Through continuous efforts, we have reason to believe that the vision of "making people enjoy a cleaner and more beautiful home" will be realized one day.

In a word, Air Purification is not only a profound reflection on the current environmental situation, but also an active exploration of future sustainable development. This is not only the awe of nature, but also the process of human self-redemption. Let's work together to win the war without smoke and jointly protect this blue sky.
