Qiu Baoxing, Vice-minister of Construction Of China, has said that our country is "facing a more serious water crisis(危機) than any other country in the world." And the Chinese government would raise the cities' waste water treatment rate(率)from 45.6% t0 60% in five years.

"Because water plays such an important role in our country's economy(經(jīng)濟)and people's life, we must pay much attention to it. We have to solve the problem before it is too late." warned Qiu. He said China should learn lessons from developed countries. They have paid heavy costs in solving the environment pollution, "We must take action before the city water ecosystem collapses(生態(tài)惡化)." Qiu said.

Qian Yi, professor of environmental engineering,' said that two problems--the shortage of water resources(資源)and the pollution of water cause China's water crisis. He said China's present water availability is still low, about a fourth of the world average level. By 2030, the number will drop much. What's worse, among China's seven main rivers, five have been seriously polluted. The worst is the Haihe River near Beijing and Tianjin.
