Today, with the continuous development of human society, environmental problems are increasingly prominent, especially the air quality problem has become one of the focuses of global attention. Air pollution not only affects people's health, but also causes serious damage to natural ecosystems, thus threatening the biodiversity of the earth and climate change. Therefore, air treatment has extremely important environmental protection significance.

1. Protect public health

Harmful substances such as fine particulate matter (PM2.5), sulfur dioxide and nitrogen oxides in air pollution can penetrate deeply into the human respiratory system and even the blood circulation system. Long-term exposure to such an environment will increase the risk of cardiovascular diseases and respiratory diseases, and may even lead to premature death. By effectively controlling and reducing the discharge of these pollutants, the morbidity and mortality can be significantly reduced and people's quality of life can be improved.

2. Maintain ecological balance

Air pollution has also done great harm to nature. The phenomenon of acid rain is that excessive SO2 and NOx in the atmosphere combine with water vapor to form acidic precipitation, which leads to soil acidification, forest withering and fish death in lakes. In addition, the hole in the ozone layer is partly due to the release of chemicals such as chlorofluorocarbons into the atmosphere. Strengthening air quality management is helpful to slow down the deterioration trend of such ecological environment and promote the recovery and development of biodiversity.

3. Respond to global warming

Greenhouse gases such as carbon dioxide (CO2) and methane (CH4) are one of the main factors causing global warming. A large number of CO2 emissions from industrial production, transportation and other activities have greatly aggravated this process. Implementing effective air pollution prevention and control measures, such as promoting the use of clean energy, optimizing energy structure, and improving energy efficiency standards, can curb the global average temperature rise to a certain extent and contribute to mitigating climate change.

conclusion

In a word, air control is not only a necessary means to improve the living environment and protect people's health, but also an important way to maintain ecological security and meet global challenges. In the face of the increasingly severe air pollution situation, governments and all sectors of society need to work together to adopt more active and effective policies and measures to promote the transformation of green and low-carbon development mode and jointly protect the beautiful home on which we live.
