World Oceans Day is celebrated on June 8th each year. Proposed at the Earth Summit in Rio de Janeiro in 1992 and officially recognized by the United Nations in 2008, the day raises awareness about the importance of oceans, which cover more than 70% of the Earth's surface and produce over half of the oxygen we breathe. The day highlights threats to oceans, including plastic pollution, overfishing, and climate change-driven warming and acidification. Events include beach cleanups, educational campaigns, and advocacy for marine protected areas.
