It's winter! The smog once again invaded the whole country. Can a variety of trees effectively reduce smog?

The smog strikes again, and it should not be blamed that trees can't solve the smog. It is impossible to solve the smog by planting trees unilaterally. To solve the smog problem, we need to find a new way through multi-party linkage.

To control smog, you must know what smog is. Fog refers to small water droplets dispersed in the air, and haze refers to dust particles floating in the air. The two are attached together to form smog, which is mainly caused by industrial dust, floating dust and automobile exhaust.

Planting trees can't see the effect of smog prevention for many years, because trees can do photosynthesis, but they can't absorb dust and tail gas. It is unrealistic to control smog simply by planting trees. Another point is that although trees have been planted for many years, the yield of trees is not high. You should know that planting trees is mainly for wind and sand fixation. When winter comes, the leaves are gone. How can the bare trunk block the smog? What can I do to stop the smog? This is not that trees are not smog-proof, but that the geographical conditions in which trees are located cannot prevent smog. On the other hand, let's think about trees in the south. They are evergreen all year round and the trees they grow can play a role. This is common sense.

The effect of reducing smog weather simply by planting trees will naturally not be too obvious. As we all know, North China, Northeast China and Northwest China are important industrial areas in China. On the map, we can clearly see that many large chimneys are erected in small areas of various regions. Basically, these chimneys emit yellow smoke all day. Is industry smog? The biggest contributor? . I remember that when the smog was the worst, netizens once cursed these industrial enterprises online, hoping that these industrial enterprises could stop working to reduce the smog weather. However, if you really did this at the beginning, it would be tantamount to giving up eating because of choking. The closure of industrial enterprises will not only bring losses to enterprises, but also cause more social problems.

On the issue of smog prevention and control, the effect of planting trees is not good. How should we solve it?

People have been thinking about how to deal with the smog problem effectively, but they have never found a good way. At first, in order to pursue economic development, we did not hesitate to sacrifice the environment. Now we can't repeat the same mistakes and give up economic development in order to solve the smog problem. However, if we want to continue to pursue the economy and move large enterprises abroad to ensure the living environment, it is unrealistic, and the transfer of enterprises will restrict the economic development of China to a certain extent. Therefore, in order to effectively solve the smog problem, I think we must start with technology. Relying on science and technology can not only delay economic development, but also reduce environmental pollution. This is a way to kill two birds with one stone. This idea may not be fully realized yet. I believe we will find a way slowly and then give people a piece of blue sky and fresh air.
