The World Oceans Day celebrates oceans as one of the most integral sources of life on Earth and encourages the alteration of human actions to preserve their beauty and to rethink our way of relating and understanding it. The theme of 2021 is “The Ocean: Life and Livelihoods” to remember us that oceans are the lungs of our Planet and a major source of food and medicine and a critical part of the biosphere.

The Ocean: Life and livelihoods

The ocean covers over 70% of the planet. It is our life source, supporting humanity’s sustenance and that of every other organism on earth. The ocean produces at least 50% of the planet’s oxygen, it is home to most of earth’s biodiversity, and is the main source of protein for more than a billion people around the world. Not to mention, the ocean is key to our economy with an estimated 40 million people being employed by ocean-based industries by 2030.

Even though all its benefits, the ocean is now in need of support. With 90% of big fish populations depleted, and 50% of coral reefs destroyed, we are taking more from the ocean than can be replenished. To protect and preserve the ocean and all it sustains, we must create a new balance, rooted in true understanding of the ocean and how humanity relates to it. We must build a connection to the ocean that is inclusive, innovative, and informed by lessons from the past.

“The Ocean: Life and Livelihoods” is the theme for World Oceans Day 2021, as well as a declaration of intentions that launches a decade of challenges to get the Sustainable Development Goal 14, “Conserve and sustainably use the oceans, seas and marine resources”, by 2030.

A second fully virtual event and a decade for Oceanographic Science

World Oceans Day reminds every one of the major role the oceans have in everyday life. They are the lungs of our Planet and a major source of food and medicine and a critical part of the biosphere. 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.

The second fully virtual celebration of United Nations World Oceans Day, on 8 June 2021, will highlight the theme of The Ocean: Life and Livelihoods. Produced by the Division for Ocean Affairs and the Law of the Sea of the Office of Legal Affairs of the United Nations, in partnership with the non-profit organization Oceanic Global, and presenting partner Blancpain, this year’s annual event will shed light on the wonder of the ocean and how it is our life source, supporting humanity and every other organism on Earth.

Join us for this year’s UN World Oceans Day annual event as we hear from thought-leaders, celebrities, institutional partners, community voices, entrepreneurs, and cross-industry experts about the biodiversity and economic opportunity that the ocean sustains.

This year's theme is especially relevant in the lead-up to the UN Decade of Ocean Science for Sustainable Development, which will run from 2021 to 2030. The Decade will strengthen international cooperation to develop the scientific research and innovative technologies that can connect ocean science with the needs of society.
