With the acceleration of society, industrialization and urbanization, air pollution is becoming more and more serious, which has become one of the important factors restricting sustainable development. In the face of this challenge, the implementation of the overall renewal of air purification is not only an urgent need to improve people's quality of life and protect public health, but also an inevitable choice to promote the construction of ecological civilization and realize green development. The purpose of this paper is to discuss the significance of global renewal of air purification and put forward corresponding strategic suggestions.

First, the importance of global renewal of air purification

1. Health benefits: The improvement of air quality is directly related to human health. According to the World Health Organization, millions of people die prematurely every year from heart and lung diseases caused by air pollution. These risks can be significantly reduced by reducing pollutant emissions.

2. Economic benefits: In the long run, investing in clean energy technology and environmental governance will promote the development of new industries, create employment opportunities, and reduce the burden on the health care system.

3. Ecological value: Purifying the air helps to protect the natural ecosystem from damage, maintain biodiversity, and is also of great significance for coping with climate change.

Second, the challenges faced

Although the benefits of air purification are obvious, there are still many obstacles in actual operation:

-High technology costs, especially for developing regions;

-Insufficient enforcement of laws and regulations, and some enterprises and individuals have evaded their responsibilities;

-Lack of public awareness, participation and support.

Third, the strategy to promote the global renewal of air purification

1. Increase investment in scientific research and promote technological innovation: The government should increase its support for environmental protection technology research and encourage universities, research institutes and enterprises to cooperate to develop low-cost and efficient air purification solutions.

2. Improve the system of laws and regulations, strengthen supervision and law enforcement: establish and improve relevant legal systems, and clarify the responsibilities and rights of all parties; Strengthen the supervision mechanism to ensure that all measures are effectively implemented.

3. Raise people's awareness of environmental protection and advocate a green lifestyle: enhance citizens' sense of responsibility through education and publicity, and guide people to take practical actions such as low-carbon travel, energy conservation and emission reduction.

4. International exchanges and cooperation to share successful experiences: actively participate in global environmental protection actions, share information resources and technological achievements with other countries, and jointly deal with cross-border environmental pollution problems.

In a word, air purification is a systematic project, which requires the joint efforts of all sectors of society to achieve results. Only when everyone is aware of the impact of their actions on the environment and actively changes, can we truly achieve the goal of solving the problem from the source. In the future, let's walk hand in hand and create a better tomorrow under this blue sky and white clouds!
