Attenborough's most significant movie

Sir David Attenborough unveils what may be the most significant film of his long career. Titled Ocean, the documentary aims to play a key role in preserving biodiversity and combating the effects of climate change.

"After nearly a century on Earth, I’ve come to realise that the most vital part of our planet isn’t on land—it’s in the ocean," says Attenborough, who turns 99 this Thursday, in an interview with the BBC.

Ocean with David Attenborough premiered on Tuesday at London’s Royal Festival Hall. The event drew notable attendees including King Charles, Prince William, singer Geri Halliwell-Horner, astronaut Chris Peake, and model Cara Delevingne.

The film explores the dramatic changes the oceans have undergone during Attenborough’s lifetime and highlights the urgent choices now facing humanity. One major focus is the environmental destruction caused by bottom trawling, a fishing method Attenborough describes as a stark example of how industrial practices are depleting marine life.

"It's difficult to think of a more inefficient and destructive way to harvest fish," he remarks.
