Sand mining destroys habitats, dirties rivers and erodes beaches, many of which are already losing ground to rising sea levels. When miners dig out layers of sand, riverbanks become less stable. The pollution and acidity can kill fish and leave less water for people and crops. The problem is made worse when dams upstream prevent sediments …
