The Three Gorges Dam is a model for disaster, yet Chinese companies are replicating this model both domestically and internationally. Within China, huge hydropower cascades have been proposed and are being constructed in some of China’s most pristine and biologically and culturally diverse river basins - the Lancang (Upper Mekong) River, Nu (Salween) River and upstream of Three Gorges Dam on the Yangtze River and tributaries.The environmental impacts of the project are profound, and are likely to get worse as time goes on. The submergence of hundreds of factories, mines and waste dumps, and the presence of massive industrial centers upstream are creating a festering bog of effluent, silt, industrial pollutants and rubbish in the reservoir. Erosion of the reservoir and downstream riverbanks is causing landslides, and threatening one of the world’s biggest fisheries in the East China Sea. The weight of the reservoir's water has many scientists concerned over reservoir-induced seismicity. Critics have also argued that the project may have exacerbated recent droughts by withholding critical water supply to downstream users and ecoystems, and through the creation of a microclimate by its giant reservoir. In 2011, China's highest government body for the first time officially acknowledged the "urgent problems" of the Three Gorges Dam.
