With the acceleration of society, industrialization and urbanization, the problem of air pollution has become increasingly serious, which has become one of the important factors affecting people's health and social sustainable development. Facing this challenge, it is particularly important to take effective environmental protection actions to improve air quality. This paper will discuss how to participate in air purification through practical actions from three levels: individuals, enterprises and the government.

Personal contribution

1. Reduce the use of motor vehicles: encourage walking or cycling to and from work, and try to choose public transport for short trips to reduce automobile exhaust emissions.

2. Energy-saving and emission-reduction life: Pay attention to saving electricity and water in daily life, such as turning off unused electrical equipment and using energy-saving light bulbs, so as to reduce the demand for fossil fuels.

3. Garbage classification and recycling: correctly classifying garbage and actively participating in recycling activities can effectively reduce air pollution caused by burning garbage.

4. Afforestation: Participating in or supporting tree planting activities and increasing the green area will help absorb carbon dioxide and other harmful gases and purify the air environment.

Corporate responsibility and practice

1. Application of cleaner production technology: Industrial enterprises should actively adopt advanced environmental protection technologies and clean energy sources, such as solar energy and wind energy, to reduce pollutant emissions.

2. Green supply chain management: establish green procurement standards, give priority to the selection of environmentally friendly materials and service providers, and promote the development of the entire industrial chain in a greener direction.

3. Social responsibility investment: increase investment in environmental protection projects, such as supporting the research and development of new air purifier products and technologies, and contribute to solving air pollution problems.

Government policies and measures

1. Formulate strict laws and regulations: introduce and improve relevant environmental protection legal system, strictly control industrial waste gas emission standards, and increase penalties for illegal sewage discharge.

2. Promote new energy vehicles: give certain preferential policies to purchase and use new energy vehicles, and speed up the withdrawal of traditional fuel vehicles from the market.

3. Strengthen public education and publicity: use various media platforms to popularize the knowledge of air pollution prevention and control, raise the awareness of environmental protection of the whole people, and form a good atmosphere for the participation of the whole society.

In short, in the face of the severe air pollution situation, everyone should shoulder their own responsibilities and start from themselves. At the same time, we should also call on all sectors of society to work together to build a beautiful China and make blue sky and white clouds the norm.
