Professor Lei Hengshun, an environmentalist at Chongqing University who has devoted years to studying and preserving the Three Gorges ecosystem, says that if the water level of the reservoir reaches its planned height of 165 meters next year, it will bring tributaries of the Yangtze River under even greater environmental threat. "Now it's a good time to review the problems that have arisen," he says, "before a larger flooded...
