Award-winning broadcaster and natural historian David Attenborough and longtime collaborator Colin Butfield present a powerful call to action focused on our planet's oceans, exploring how critical this habitat is for the survival of humanity and the future of Earth.

Through personal stories, history and cutting-edge science, Ocean uncovers the mystery, the wonder and the frailty of the most unexplored habitat on our planet – and the one which shapes the land we live on, regulates our climate and creates the air we breathe. The book showcase the oceans' remarkable resilience: they are the part of our world that can, and in some cases has, recovered the fastest, if we only give them the chance. 

Drawing a course across David Attenborough's own lifetime, Ocean takes readers on an adventure-laden voyage through eight unique ocean habitats, through countless intriguing species, and through the most astounding discoveries of the last 100 years, to a future vision of a fully restored marine world, even richer and more spectacular than we could possibly hope. Ocean reveals the past, present and potential future of our blue planet. It is a book almost a century in the making, but one that has never been more urgently needed.
