# Sir David Attenborough is launching what he says is one of the most important films of his career as he enters his hundredth year. He believes his new, cinema-length film Ocean could play a decisive role in saving biodiversity and protecting the planet from climate change. Sir David, who will turn 99 on Thursday, says he now understands the most important place on Earth is not on land, but at sea. The film documents how the state of the world’s oceans have changed in the course of his life.
