The smog weather in Beijing is so bad, is there any way to improve it?

1) burning coal: I'm sure that if Beijing and Hebei lose power for three days in a row, steel mills and cement plants will stop working to ensure that the smog will all disperse. Of course, this has seriously affected people's lives and cannot be implemented. But it can be reduced. For example, reduce the power generation of power plants, reduce the output of steel mills and cement plants and so on. Stop chasing your GDP. Similarly, ordinary people have developed the habit of saving and reducing energy consumption. Therefore, in the long run, the government should make great efforts to change China's high dependence on coal and turn to other clean energy sources, such as natural gas; In the short term, the government should force the chimneys of power plants, steel mills and cement plants to install filter devices to make their emissions reach a certain standard. I think this is the fastest and most effective way. It shouldn't be difficult, but I don't know why the government always looks around and talks.

2) Urban structure: As mentioned above, it is imperative to learn the lessons of the next urbanization, build more small towns and reduce the number of big cities; In big cities, the construction of "lungs" such as farmland, orchards and forests can give the city a "breath". Change people's living, traveling and employment habits in big cities, and reduce the daily flow of people or the distance between people.

3) For automobiles: strictly control the number of automobiles in cities, and improve the quality of oil products and automobile exhaust filtration technology.

4) Common people form the habit of saving and reducing everyone's energy consumption.

5) What other construction sites, kebabs and so on. , are properly controlled, just as these are not the main ones.

If I can only do the first thing I said, I believe the smog will be greatly improved. Why does the country prefer to let everyone wear masks instead of factory chimneys? What is the use of developing GDP in this way?
