Sand resources are the most extracted solid material on Earth. They are also among the most undervalued despite how essential they are to nature and development. Extracted, they are used to build homes, highways, solar panels, sea walls, and for land reclamation in coastal cities. Left in place, sand regulates rivers, protects coastal aquifers, filters water, sustains biodiversity, maintains habitats, buffers coastlines against storm surges, and supports fisheries and tourism that billions depend upon.
