It is time to realize that, to achieve the Sustainable Development Goals and the objectives of the Paris Agreement on climate change, we urgently need collective action to revitalize the ocean. That means finding a new balance in our relationship with the marine environment.

Revitalization: collective action for the ocean

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. We need to work together to create a new balance with the ocean that no longer depletes its bounty but instead restores its vibrancy and brings it new life.

"Revitalization: collective action for the ocean" is the theme for World Oceans Day 2022, a year framed by the UN Decade of Ocean Science and the celebration of the United Nations Ocean Conference, two years after being cancelled because of the pandemic.

Join us and celebrate the value of oceans

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.

This year, the United Nations will host the first hybrid celebration of the annual event on 8 June 2022, hosted in-person at the UN Headquarters in New York to be broadcasted live. It will highlight the 2022 theme of “Revitalization: collective action for the ocean”.

Hosted by the Division for Ocean Affairs and the Law of the Sea of the Office of Legal Affairs of the United Nations, with the generous contribution of the non-profit organization Oceanic Global, and made possible by La Mer, this year’s annual event will shed light on how we can work together to ensure the ocean’s health and well-being.

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.

The Ocean Conference (27 June- 1 July) has finally arrived after 2 years canceled because of the pandemic. Co-hosted by the Governments of Kenya and Portugal, the Conference will seek to propel much needed science-based innovative solutions aimed at starting a new chapter of global ocean action.

What do the deepest point in the ocean, the Mariana trench, and the highest mountain peak in the world, Mt. Everest, have in common? Despite being among the planet's most inaccessible environments, they both contain tiny pieces of plastic from human activities miles away. Discover in this visual report the problem of garbage in the oceans. More interactive and visual stories here.

International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
