Answer: UNEP
Notes: A new global data platform, Marine Sand Watch, developed by GRID-Geneva within the UN Environment Programme (UNEP), has unveiled that six billion tonnes of sand are being extracted annually from the world's ocean floors, posing irreparable harm to benthic life. The platform monitors sand, clay, silt, gravel, and rock dredging in marine environments, particularly in hotspots like the North Sea, Southeast Asia, and the East Coast of the United States.
