Dec 10, 2019 Sand mining is a human activity that is increasing in inland waters and has profound effects on entire aquatic ecosystems. However, current knowledge of the effects of sand mining on freshwater lake ecosystems remains limited, especially for biotic communities. The sand mining process can also have a negative impact on the wildlife of an area as well, because the fragile habitat of many coastal fish, animal and plant species can be disrupted if the process is not carefully monitored. Although there are laws in place to prevent such over-mining in many locations, illegal sand mining often still occurs.
