As he nears his 99th birthday, Sir David Attenborough – the beloved voice of the natural world for generations – has delivered perhaps his most emotional and urgent message yet: time is running out, not just for him, but for the planet.
In a new documentary titled Ocean: With David Attenborough, set to release in cinemas on May 8 – the very day he turns 99 – the legendary broadcaster confronts the fragility of Earth’s ecosystems with stirring honesty. It is a deeply personal reflection on a lifetime of observing the planet’s wonders and wounds.
“Now, as I approach the end of my life,” he says, “we know the opposite is true,” referring to the misguided idea that the sea was once a wilderness to be conquered. “The key to saving the planet is not on land, but at sea.”
These words don’t come from a man resigned to despair, but from one who has spent nearly a century in awe of the world’s resilience. And yet, Attenborough doesn’t shy away from the pain of witnessing environmental decline. “The planet is in such poor health,” he admits, “that I would find it hard not to lose hope – were it not for the ocean.”
It is here, in the depths of Earth’s oceans, that Attenborough finds not only scientific promise but emotional solace. “If we save the sea, we save our world,” he declares with conviction. “After a lifetime of filming our planet, I’m sure nothing is more important.”
The documentary, as sweeping as it is intimate, takes viewers across oceans in the Americas, Europe, Africa and Oceania, exploring coral reefs, mangroves, coastal communities, marine sanctuaries and more. It highlights bold efforts by scientists and communities working to reverse the damage caused by humanity’s relentless exploitation – efforts that offer not only solutions but hope.
With characteristic reverence and poetic clarity, Attenborough traces the sea’s central role in sustaining life on Earth. The film does more than educate – it pleads for connection, for urgency, for action.
From Zoo Quest in the 1950s to Life on Earth, The Blue Planet, Planet Earth and Dynasties, Sir David’s work has been a chronicle of the natural world’s magnificence and its mounting distress. But never before has his message felt so personal – or so final. It’s a legacy project: not just a film, but a farewell letter from a man who has given his life to showing us the beauty of this planet.
