Pirate fishing, oil spills and other undetected crimes are destroying ocean ecosystems -- but we can't stop what we can't see. Harnessing the power of satellite data and AI to catch maritime offenders in the act, ocean conservation expert and 2023 Audacious Project grantee Tony Long introduces the first-ever live map of all industrial human activity at sea. He shares how his team at Global Fishing Watch is making it freely available to the world so conservationists, researchers and the public can help protect precious aquatic habitats. (This ambitious idea is a part of the Audacious Project, TED's initiative to inspire and fund global change.)
