Sand Mining Is Stealing The Minerals From Chinese Rivers

Sand mining has led to deepening and widening of the Lake Poyang channel, the largest freshwater lake in China and a biodiversity reserve of exceptional importance, and to an increase in water discharge into the Yangtze River. This may have influenced the lowering of the lake’s water levels, which reached a historically low level in 2008.The Platte River lies just north of the Rainwater Basin (Fig. 1) and is comprised of a braided river of multiple channels and associated oxbow lakes and wet meadows (LaGrange 2005). Gravel pit and sand mining operations also occur in the Central Platte River Valley, which provide deepwater habitats. The river valley.
