How long will the smog weather last in Shanghai?

Shanghai is by the sea, and the air quality has always been excellent before, and I never know what smog is

But the air quality has obviously decreased in recent years, and I don't think it will be fundamentally improved in the next decade-

Is it possible for the air in Shanghai to be good? You don't have to think about it!

Shanghai is a tiny place. It's only a small spot on the map, but it has a population of more than 3 million, which is more than 1 million more than the national population of Australia. People with normal brains know very well that it is a daydream to have good air in such a city.

the meteorological observatory and the media said that the smog was caused by the climate, and it was really a joke to wait for the cold air to go south to lift the smog! The government is still looking for various reasons to explain the source of smog and shirk its responsibility. This explanation is pale and unconvincing. If you don't make efforts to control the population, everything is nonsense! Cities in the whole eastern region have problems, and Shanghai is not the only place. Judging from the attitude of the government, they will not admit their mistakes first, and will not change if they don't admit it. They will still put GDP in the first place and leave ecological civilization behind. Shanghai will continue to build large-scale buildings, build endlessly and introduce population endlessly, and it will still sell 1, private car licenses every year. . . . . . If this continues, it will not improve in 1 or 2 years. In the final analysis, the root cause of smog is human self-emission, and the main reason is that there are many people! If this problem is solved, 99% of the environmental problems will be solved.
