The smog in Huanghuai, North China hit again and planted trees for many years. Why is the smog still unresolved?

You're kidding! You're kidding! Does anyone really think that planting trees can make smog disappear forever? Smog cannot be purified by plants alone. Humans don't try to change themselves, but force plants to solve human destiny? Don't you think it's a little funny?

What is smog?

The main sources of smog are industrial dust, dust and automobile exhaust. As far as these pollution sources are concerned, as long as human beings want economy and development and cannot find the most effective purification method at present, they will always exist. During the epidemic, the factory stopped working and the construction site did not go to work. Did the sky in North China suddenly turn blue? Fog is water droplets suspended in the air, haze is dust, and smog is caused by human beings, which affects human health and pollutes the atmosphere. This need not be washed white. Humans just want to bear the consequences of their own destruction of the environment and repair it themselves.

Why is the smog in North China difficult to solve?

Trees do have a certain purification effect on the air, but in the past ten years, all the trees planted in North China are desert areas, which are trees for greening and preventing desertification, but they are still unable to cope with smog. In addition, North China started sustainable development by relying on heavy industry. Without heavy industry, the air is fine. What do ordinary people eat and drink from the northwest wind? In addition, due to the topography of North China, how much green can be seen in winter, and plants have no chance to absorb and purify smog. Look at Guangdong and other places. The climate is warm all year round, with lush plants and high coverage. Nature can have blue sky. Therefore, the development, climate and geographical location of North China make it difficult to solve the smog in North China. In North China, the atmosphere is difficult to flow, and the smog can't be blown away.

How to solve the pain of smog, frankly speaking, is really difficult. Friends living in North China should be able to clearly feel that the smog is coming earlier and earlier, the air quality is getting worse and worse, and more and more children go to the hospital for treatment every year. To solve the pain of smog, we must sacrifice the economy. But as a developing country, does China really dare to do so? Only when the economy develops can the military develop and the country become strong. At present, we can only actively seek economic transformation and save the foggy days without sacrificing the economy. I hope that besides heavy industry, North China can also find industries that can continue to develop. But it is quite difficult, because if heavy industry is transferred abroad, it will still restrict the development of our country.

For today, I still expect a lot of snow in winter. Snow can effectively alleviate smog. But it depends on heaven whether it snows or not. Which is more important, economic development or a healthy future, has different weights in different times. The only thing we ordinary people can do is to reduce environmental pollution and do our bit. A single spark can start a prairie fire, which may have some effect on improving smog.
