Coastal and river regions put up with erosion, and sediment deposits from mining degrade water top quality and demolish habitats. Extraction from rivers and beach locations impacts biodiversity and infrequently contributes to tensions with regional communities that trust in pure resources. The growing scarcity has even resulted in "sand wars," specifically in areas with increasing development demands.
This type of sand originates through the erosion of quartz-loaded rocks, including granite, whose particles are transported by rivers and winds around fantastic distances to the sea. The chemical balance and rounded form in the grains provide the sand a lengthy lifespan, letting it to persist for many many years.
