The weather is Qihe.

Now Beijing and Shanghai can be said to be first-tier metropolises, and then the dusty weather in these places is also the most serious. Whenever dry winter comes, dusty weather is the most frequent. Dust weather also shows that the environment in our country is getting worse, but before the reform and opening up, the environment in China was not so bad. Why are there dusty weather in so many provinces now? The main reason is that society has neglected something in the process of development. Although society is progressing, we have been doing things that destroy the environment. Everyone looked around. Are there many tall buildings, but houses are still being built around them? ? As a result, the housing area has increased, the vegetation area has been seriously reduced, and the dust is mainly blocked by green plants, so that the part of green plants that should have blocked the dust has been replaced by buildings.

However, we have not only reduced the number of green plants that block dust, but more importantly, we have also set up many steel mills in the process of social progress. But in the process of steelmaking, we will need to burn a lot of firewood and coal, and these coals and firewood will constantly produce some waste particles and dust substances during the combustion process. As a result, there are more and more dust particles in the air, which will gradually cause serious dust. The dust in the air will float to all parts of the country with the wind, which also causes the dust weather to spread to half of the provinces in China. Therefore, we also need to vigorously protect the environment while social development, otherwise it will be our own human beings who will be hurt in the end. Nowadays, many children are born with respiratory diseases, which is also caused by too much dust in the air. I hope everyone can pay attention to the environment.
