Renowned British biologist and broadcaster Sir David Attenborough and his collaborator, environmentalist and producer Colin Butfield, explore the extraordinary and increasingly fragile world of oceans and ocean-dwellers.

British biologist and broadcaster Sir David Attenborough is one of the most beloved voices in natural history.

He has spent over seven decades documenting the wonders of the planet, inspiring generations to get involved in the study and conservation of nature.

At nearly 100 years old, Attenborough is now witnessing the unsettling effects of climate change destroy and endanger the world he spent a lifetime exploring.

Co-written with environmentalist and producer Colin Butfield, Ocean: Earth's Last Wilderness is Attenborough's 2025 book about the mysteries and marvels of our seas, and aims to remind the world how much we collectively depend on healthy marine habitats.
