Oyster Conservation and Ecosystem Benefits

The video discusses the global water crisis, highlighting pollution as a major threat. It focuses on New York Harbor's historical marine ecosystem, once rich with oysters, and the efforts to restore it through the Billion Oyster Project. Oysters play a crucial ecological role by filtering water and providing habitat. The project aims to restore these functions, potentially protecting the harbor from environmental threats.
