Beijing with a blue sky: impossible mission?

Last week I mentioned in my post that Beijing had a blue sky for many days in the past two months. This beautiful sky did indicate that the air in Being was clean in those days. During the huge military parade period, the average PM 2.5 in Beijing was only 18 µg/m³ .

Although the blue sky was only short-lived for some days, its appearance in Beijing was really significant. It proved to the public that Beijing can have a blue sky if a lot of efforts are put to control the air pollution. According to Liu Qin,a editor of Chinadialogue, Beijing's blue sky is a result of shutting down a lot of industries nearby and controlling the number of motor vehicles (Liu, 2015). Moreover, more stringent regulations on air pollutants also contribute to the clean air in Beijing. Besides the government, some creative individuals also try to help alleviate the bad air pollution in Beijing with their own idea. For example, recently the Dutch architect Daan Roosegaarde designs the biggest air purifier the Smog Free Tower and plans to give it a tour to Beijing. He aims to relate citizens to air quality protection by exhibiting the Tower in Beijing (Walker, 2015).

As the capital city of the biggest developing country in the world, Beijing eventually showed that cleaning the heavily polluted air in less developed countries or industrialized countries is not an impossible mission to the rest of the world.

Here is a video of "Parade Blue" in Beijing:
