About the title
99-year-old Sir David Attenborough explores the planet's underwater habitats, telling the story of the greatest era of ocean discovery and highlighting the ocean's vital importance, while also revealing its problems and the opportunities to restore marine flora and fauna. Stunning, gripping cinematography showcases the wonder of life beneath the sea and lays bare, as never before, the realities and challenges facing our ocean — from barbaric fishing methods to the mass destruction of coral reefs. Nevertheless, the story is full of optimism, and Attenborough draws on inspiring stories from around the world to deliver his greatest message: the ocean can recover to a grandeur surpassing anything anyone alive has ever seen.
