In the 21st century, with the acceleration of industrialization and urbanization, air quality has become one of the focuses of global attention. Air pollution not only affects people's health, but also restricts economic and social development, from the metropolis with frequent smog to the small towns with dense industrial areas. Faced with this challenge, governments and all walks of life have taken measures to formulate and implement a series of goals and plans aimed at improving air quality and protecting the environment. This paper will discuss the importance of air treatment and its realization path, and express the expectation of environmental protection for a better future.

Present situation and challenges of air quality

In recent years, although many countries and regions have made some achievements in reducing pollutant emissions, overall, the global air quality situation is still not optimistic. According to the report of the World Health Organization, millions of people die prematurely every year because of air pollution, among which PM2.5 (fine particles) is one of the main factors causing this phenomenon. In addition, the excessive ozone and the rising concentration of harmful gases such as sulfur dioxide are also urgent problems to be solved.

Governance goal setting

In order to meet the above challenges, the international community generally calls for strengthening cooperation and working together to build a clean and beautiful earth home. In this context, the United Nations sustainable development goals clearly put forward to ensure that all people can enjoy safe, clean and affordable energy; At the same time, various countries have also formulated corresponding long-term plans and short-term action plans according to their actual conditions. For example:

-China put forward a three-year action plan to win the blue sky defense war;

-The European Union issued the "European Green Agreement", aiming at achieving carbon neutrality by 2050;

-India launched a national air purification project, focusing on reducing the level of PM2.5 in major cities.

Realize path exploration

To effectively improve air quality, we need a multi-pronged approach and comprehensive policies. First, promote the optimization and upgrading of industrial structure, limit the development of industries with high energy consumption and heavy pollution, and encourage the development of low-carbon economy and technology; Secondly, increase the promotion of new energy vehicles, improve the efficiency and service quality of public transport systems, and reduce vehicle exhaust emissions; Thirdly, strengthen the construction of laws and regulations, strictly implement environmental protection standards, and increase the punishment for illegal sewage discharge; Finally, enhance public participation awareness, popularize scientific knowledge and advocate a green lifestyle.

Air is one of the basic conditions for our survival, and everyone should be a supporter and practitioner of environmental protection. Only with the joint efforts of the whole society can we make the sky bluer, breathe more smoothly and leave a beautiful world full of vitality for future generations. Let's join hands to move towards the goal of air control and meet a more brilliant tomorrow!
