Theme for 2021: “The Ocean: Life & Livelihoods”

Home
The concept of a World Oceans Day was first proposed in 1992 at the Earth Summit in Rio de Janeiro as a way to celebrate our world’s shared ocean and our personal connection to the sea, as well as to raise awareness about the crucial role the ocean plays in our lives and the important ways people can help protect it.
The purpose of the Day is to inform the public of the impact of human actions on the ocean, develop a worldwide movement of citizens for the ocean, and mobilize and unite the world’s population on a project for the sustainable management of the world’s oceans.
