Everyone knows that China has big problems of pollution, as well in the air as in the water. Thus Beijing has reached record highs in the peaks of air pollution, which has seen well this year in the international media.
Another example a little crazy is the story of the thousands of pigs found in the Huangpu, or the drowned ducks, all this happened this year.
The government is concerned about these problems because the international scene is constantly pointing to China for its pollution problems. However, the authorities had displaced many factories during the preparation of the Beijing Games in 2008, or the Shanghai World Expo in 2010. But that was clearly not enough.
However, although this sector is conducive to foreigners, care must be taken because there are many connections to government in the community that can cause problems.
