Can sand mining ever be green? Mining Technology
2017-6-19 Sand mining can severely damage environments and ecosystems. Often mined by dredging sea and river beds, the practise poses a threat to biodiversity as creatures and plants are stripped from the depths, and the stirred up plumes suffocate fish and block sunlight from the remaining underwater vegetation. Along riverbanks, mining has changed the
