Air Pollution in Beijing, China
Air pollution in China is one of the major problems, but in some recent years this conditions improved a lot. In this video I tried to show the example of air pollution in Beijing. During this time the amount of PM 2.5 was very high in the air. But this kind of situation is very few in some recent years due to the initiative of Chinese Government. Now most of the time Air condition is quite good and you can see the blue sky.
