    4. Sand Mining Makes Areas More Prone to Flooding. Beaches, dunes, and sandbanks act as barriers to flooding. When sand mining removes such barriers, areas near the sea or river become more prone to flooding. As a result, beachside communities in areas subjected to indiscriminate sand mining are thus more vulnerable to the forces of nature. 5.
