Sand mining is stealing the minerals from Chinese rivers

2021-2-11  Unsustainable sand mining transforms the structure of rivers. By removing more than the river can naturally replace with the sediment it carries downstream, sand mining carves a deeper, narrower bed. This lowers the water level, speeds up flow and erodes banks – reducing the watershed’s capacity to absorb excess water during floods.
