Beijing was struck by serious air pollution. The authority declared a “red alert,” suggesting shutting schools and stores down for five days. It was reported that hundreds of people were penalized for igniting outdoor barbecues.
The Guardian: Beijing smog: pollution red alert declared in China capital and 21 other cities
The smog is not rare in Beijing and some other cities in China. A Huge amount of coal is burned there for industrial purposes. It causes PM2.5 which is a kind of tiny particle potentially harmful to human body. China is rapidly developing its ability to create industrial products. However, the importance of the protection of the environment is underestimated.
It is not limited to China: air pollution and other harms for the environment is a common issue in developing nations because their limited financial resource does not allow to watch out the environment. Also in Japan, some issues regarding air and water pollution were focused soon after the WWII.
After all, refraining from pollution should be a world challenge. Banning coal burning in China is unfeasible. Rather, technical and financial aids for China to develop less-risky factories is hopeful for the longitudinal point of view.
Environmental science is an immature and fragile region of academics. It is still unsure how to treat global warming. Extensive experiments are needed. Supporting developing countries, such as China, even if China is no more a developing country, is a model for preventing further pollution.
