David Attenborough’s voice has been a powerful guide for millions, educating audiences on the wonders of the natural world and the urgent need to protect it. His latest documentary, Ocean with David Attenborough, highlights the majesty and fragility of our ocean. The documentary is a breathtaking reminder of the deep connection between humanity and the ocean, while urging us to take action to safeguard these vital ecosystems. With a global Ocean Treaty on the horizon, this documentary calls for collective action to preserve the ocean that sustains life on Earth.

The powerful documentary film from Silverback Films and Open Planet Studios is set for release as a global cinema event from 8 May (2025), which also coincides with David Attenborough’s 99th birthday. The film will be available on streaming services globally on world oceans day on the 8th of June.

The film’s release is timed ahead of World Ocean Day (8 June 2025), June’s United Nations Ocean Conference 2025 where it will be screened (9 June – 13 June) in Nice, France, and midway through the United Nations Decade of Ocean Science for Sustainable Development (2021-2030). As world leaders decide the fate of our ocean, Ocean with David Attenborough will show why ocean recovery is vital for stabilising our climate and securing a healthier future for us all, and how marine protection – if immediately implemented – can help to turn the tide.

The Ocean’s Vital Role in Our Planet’s Health

Overfishing, plastic pollution, rising temperatures, and habitat destruction are pushing marine life to the brink. In The Ocean: A Journey with David Attenborough, viewers are invited to witness the wonders of the ocean, from its deepest trenches to its vibrant coral reefs. The film is not just a visual spectacle but also an urgent call for action. Attenborough’s narration, as always, blends awe with concern, urging us to recognise the ocean’s importance and the urgency of preserving it.

“My lifetime has coincided with the great age of ocean discovery. Over the last hundred years, scientists and explorers have revealed remarkable new species, epic migrations and dazzling, complex ecosystems beyond anything I could have imagined as a young man. In this film, we share some of those wonderful discoveries, uncover why our ocean is in such poor health, and, perhaps most importantly, show how it can be restored to health. This could be the moment of change. Nearly every country on Earth has just agreed, on paper, to achieve this bare minimum and protect a third of the ocean. Together, we now face the challenge of making it happen.”

-David Attenborough

Why the Global Ocean Treaty Matters

The Global Ocean Treaty is more than just an environmental issue—it is a matter of global responsibility. All waters of the ocean are interconnected, and its health directly affects all of us. Climate change, pollution and overfishing are pushing the ocean to the brink of collapse. Food security and the livelihoods of billions of people hang in the balance.

After years of campaigning, the first ever Global Ocean Treaty was passed at the UN in 2023, but governments now need to sign it into law, to make protected areas a reality at sea. Time is running out, and reaching this target will require a strong and urgent political response.

Australia has signed but not ratified the Global Ocean Treaty. See the list of countries that have signed and/or ratified the high seas treaty here. The new government must prioritise ratifying as a matter of urgency.

Greenpeace’s call for action is clear: to ensure the protection of 30% of the world’s ocean by 2030. We are pushing for at least 60 countries to ratify by the end of 2025 in order to support the creation of marine protected areas that are off-limits to destructive activities like deep-sea mining and industrial fishing.

In our own backyard, industrial fishing and pollution is putting immense strain on unique and diverse ecosystems. That’s why Greenpeace is campaigning to establish a marine sanctuary in the Tasman Sea.

Our beautiful blue backyard, the Tasman Sea between Australia and New Zealand has complex topography and nutrient-rich currents in these areas that create ideal conditions for species like tuna, whales, seabirds, and ancient corals to thrive. Establishing a sanctuary here would not only safeguard endangered species, like the South Pacific humpback whale and several types of albatross, but also provide a habitat for all marine life to thrive.

The Global Ocean Treaty is an essential tool for protecting life in the high seas. By creating new sanctuaries we can protect the ocean for the future. Join Greenpeace in advocating for the Australian Government to be a leader in protecting the ocean.

Together, we can protect the ocean that sustains us all.
