Air pollution in China

China's pollution now is not so much because of mining, but from coal-fired power plants, heavy industry, large amounts of construction being done and its traffic congestions. The quality of China's air is declining due to the increase in cars and heavy industries which emit harmful gases into the air, polluting it. 

These two pictures show the difference between air pollution in the Beijing Vs the air condition it is in now.

China tries to improve the air quality in Beijing by closing down factories and controlling the number of cars on the road by allowing them to drive on certain days. Chemical plants, power stations and factories that did not close down, had to cut emissions by 30% and construction work there was temporally stopped. Public transport prices were dropped to encourage people to take public transport and discourage people, at the same time, to purchase cars. These efforts by the Chinese government has significantly decreased the amount of air pollution in the city.
