📝 About World Ocean Day 2026
First proposed by Canada at the 1992 Earth Summit in Rio de Janeiro and officially recognized by the United Nations in 2008, World Ocean Day on June 8 highlights that oceans cover 71% of Earth's surface, produce over 50% of the world's oxygen, and absorb roughly 30% of human-produced carbon dioxide. The day coordinates thousands of events worldwide — beach cleanups, educational programs, art exhibitions, and film screenings — unified by annual themes addressing overfishing, marine plastic pollution, and coral reef bleaching. An estimated 8 million metric tons of plastic enter the oceans each year, and the day was instrumental in building public support for the UN High Seas Treaty adopted in 2023.
