When you think about polluted countries, China is one of the first ones that come to your mind. However, you would be surprised to find out that China actually has a very healthy air. On August 20th, Beijing has decided to make an experiment. Up to five million cars were banned, not to mention construction sites.
The polluted air quality index was at 160, which was terrible for the health. During the ban, citizens could see the blue sky again, as well as buildings in the long distance. In fact, China was proven to have a healthy air if all these things would be gone. The ban was enforced during a celebration for the 70th anniversary of Japan’s WWII withdrawal.
