About World Oceans Day
World Oceans Day celebrates the vast bodies of water that regulate climate, produce much of the oxygen we breathe, and feed billions of people. Officially recognized by the United Nations and held every June 8, it is celebrated by aquariums, schools, coastal communities, and conservation groups worldwide. A global network of organizations coordinates the campaign throughout the year.
Events include beach clean-ups, film screenings, art exhibits, citizen science projects, and policy forums on issues like overfishing, plastic pollution, and ocean warming. Annual themes rally attention to specific challenges, while a youth advisory council gives young ocean advocates a prominent voice.
The day blends wonder and warning: a moment to enjoy the sea and a reminder that its health depends on human choices. Many aquariums and marine centers offer special programs on the date.

History of World Oceans Day
The idea was first proposed at the 1992 Earth Summit in Rio de Janeiro, where Canada suggested a day to honor the world's oceans and their role in daily life. Grassroots organizations kept the observance alive for years before the United Nations General Assembly formally recognized June 8 as World Oceans Day through a resolution adopted in late 2008, with official celebrations beginning in 2009.
Since then the UN has provided an annual theme and global coordination, while local communities retain their own traditions. The day now sits alongside Earth Day as a major moment in the environmental calendar, with youth engagement playing an ever larger role.
