He warned those involved in the project that the responsibility on your shoulders is heavier than a mountain. Any carelessness or negligence will bring disaster to our future generations and cause irretrievable losses. Zhu also suggested China might invite top international engineers to inspect the dam and monitor its construction. Chinese leaders have long dreamed of taming the Yangzi for power generation and flood control. The rivers infamous floods have brought destruction and death for centuries -- 1 million deaths in the 20th century alone Dai calls Three Gorges the most environmentally and socially destructive project in the world. She also calls for a halt to construction and supports the idea of a series of smaller, less disruptive construction projects on tributaries of the Yangzi. Moreover, of further concern are claims the dam might become an environmental disaster. There have been little to no attempts made toward removing accumulations of toxic materials and other potential pollutants from industrial sites that will be inundated. Experts say such materials could leach into the reservoir, creating a health hazard. Besides, the relative lack of waste treatment plants in China also could mean run-off from communities around the dam would most likely go untreated directly into the reservoir and into the Yangzi.
