With the accelerated development of society, industrialization and urbanization, the problem of environmental pollution has become increasingly prominent, among which air pollution is the most serious. Air quality is not only directly related to human health, but also has a far-reaching impact on ecological balance. Therefore, air treatment has become one of the important issues of environmental protection worldwide.
analysis of existing circumstance
In recent years, with the joint efforts of the government and all walks of life, China's air quality has improved significantly. According to the data released by the Ministry of Ecology and Environment, in 2019, the concentration of PM2.5 decreased by 28% compared with 2015, and the proportion of excellent days reached over 82%. However, despite the remarkable achievements, there is still a big gap compared with the standards of the World Health Organization, especially in the winter heating season, the smog phenomenon in some areas is still serious.
Challenges faced
1. Industrial emission: Heavy industry is one of the main sources of air pollutants, especially around some cities with rapid economic development.
2. Automobile exhaust: The number of private cars has soared, and motor vehicle emissions have become one of the main causes of urban air pollution.
3. Unreasonable energy structure: Coal is the main form of primary energy consumption in China, and harmful substances such as sulfur dioxide produced by its combustion are the key factors causing acid rain and haze weather.
4. Insufficient public awareness: Although more and more people are beginning to pay attention to environmental issues, it is still not common to take practical actions to reduce pollution in daily life.
Suggestions for future development
Optimize the industrial structure: accelerate the elimination of backward production capacity and promote the application and development of clean energy and new energy technologies;
Promote green transportation: encourage the use of public transportation and support the research and development and application of low-carbon transportation such as electric vehicles;
Strengthen the construction of laws and regulations: improve the relevant laws and regulations system and increase the punishment for illegal sewage discharge;
Improve citizen participation: Enhance the environmental awareness of the whole people through education and publicity, and guide all sectors of society to participate in air pollution control.
In a word, air pollution control is a long-term and arduous task, which requires the joint efforts of the government, enterprises and every citizen. Only when the whole society forms a joint force can we effectively cope with this challenge and leave a beautiful home with blue sky and green land for future generations.
