CLEAN : US: Campaigners project Global Ocean Treaty demand next to Brooklyn Bridge

The video discusses the current state of ocean protection, highlighting that only 2% of the world's oceans are protected, with a goal to reach 30% by 2030 through a new treaty. It addresses the severe impact of overfishing, with 90% of large fish removed, and the lack of regulation in high seas fishing. The video also explores the dual role of oceans in climate change, both as victims and as part of the solution, emphasizing the need to stop burning fossil fuels. Finally, it stresses the importance of implementing a global ocean treaty to create sanctuaries that restore populations, protect biodiversity, and combat threats like climate change, plastic pollution, and overfishing.
