Beijing's usage of groundwater is very high, almost 65 percent of the entire water consumption.
However, he global standard for using groundwater is less than 40 percent.

The groundwater level in Beijing has been lowered from 12m in 1999 to 24m in 2010. And this is especially serious in large urban areas and economic hubs.

If the process of ground collapsing continues, not only the environment, but also human lives will suffer. 

  Beijing is the thirstiest city in China, and as population grows, the lack of water is becoming more and more severe.
