Global warming - China
The Yellow River, Huang He, gives and takes.
Jin Henin (70) has lived by the river all his life. In 1938 a flood killed several hundred thousand.
Today the problem is drought and pollution. 10 percent of the river is sewage.New super cities like New City of Zhengzhou are being constructed to accommodate a fast growing population and economy. The water demand from these cities will further stress an already exhausted river. The river is already at maximum capacity of usage.
