Beijing continuously pollutes the weather, which is better to control, sandstorm or smog?

Regarding natural environmental protection, I want to say that no matter which one is difficult to control, personally, smog is actually better than sandstorm.

First, let's talk about sandstorms. Sandstorm means that strong winds blow up a lot of dust on the ground and throw it into the air, making the air turbid. Sandstorm has a long history, and its causes have little to do with human beings. Sandstorm is a kind of natural landscape besides being close to human habitation. However, due to the development of human life and production activities, the area of sandstorm has expanded, and the frequency and intensity of sandstorm have gradually increased. Although sandstorm is harmful, the process is also an indispensable part of the natural ecosystem, and it is classified as a natural disaster only because it is harmful to human beings.

Small particles of sandstorm easily penetrate into respiratory tract, while large particles are easily inhaled into trachea and bronchus by nasal cavity, causing inflammation. At the same time, sandstorms are also easy to cause the spread of germs. Therefore, the control of sandstorms in China started from 1987, and there is a project area with a total area of 6,000 mu in the west, which is a demonstration project of rational utilization of sand resources and ecological construction in China. China not only spent a lot of time and money on controlling sandstorms, but also

At present, in addition to the support of national projects for sandstorm control, major public welfare organizations and financial companies have measures and records to improve vegetation in sandstorm areas (ANT FOREST, etc. ). It can be said that China has not slackened its efforts in controlling sandstorms.

However, the situation of smog is different. Although they are all air pollution, the latter is not as hard as the former in terms of governance, and even deliberately avoids these problems.

The principle of smog formation is the pollution caused by pollutants in the air when the air is not flowing. A large part of the reason is caused by pollution sources, and pollution sources are almost all man-made, such as factory emissions and motor vehicle exhaust emissions, which not only contain heavy metal poisons, but also smaller particles with a PM value of only 2.5, causing great harm to people's lungs. In order to reduce capital output, some manufacturers secretly do not install sewage purification equipment, but many local governments turn a blind eye to such things for GDP.

Similar to China, catastrophic smog broke out in Britain in 1952, and about 654.38+million people suffered from respiratory diseases such as asthma. In four days, more than 4,000 people died; Two months later, more than 8,000 people died. All these have made Britain determined to control the air, and it took London 30 years to get rid of the title of "Fog Capital".

The G20 blue in Hangzhou and the APEC blue in Beijing all tell us that smog is not uncontrollable or a natural problem. Everything happens to human beings themselves. The smog problem only appears in the fact that interests are more important than people's lives!
