The Ocean is the Great Connector—linking peoples, cultures, economies, and ecosystems. The Kunming-Montreal Global Biodiversity Framework (GBF) recognizes this connection, with nearly all targets containing a link to the Ocean. Ocean Day at COP 16 celebrated those relationships, uniting global actors from diverse fields, working to advance ocean conservation, research, and sustainable use. Ocean Day featured engaging, interactive events, with audience polls, videos and musical interludes, talk-show formats, and theater, designed to inspire action to accelerate efforts on implementing the GBF.
