History of World Oceans Day

World Oceans Day was first proposed in 1992 at the Earth Summit in Rio de Janeiro, Brazil, as a way to celebrate our shared oceans and raise awareness about the crucial role they play.

In 2008, the United Nations officially designated June 8 as World Oceans Day, giving it global recognition and support.

Since then, people around the world have come together every year through beach clean-ups, education drives, art, music, and policy discussions to protect the oceans.
