"Because water plays such an important role in our country's economy(經濟)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.
