Over the past 100 years, oceans have progressed from being a complete mystery to being regarded as vital for our survival, according to Sir David Attenborough.
That's almost Sir David's lifetime. The 99-year-old's latest film Ocean with David Attenborough showcases the beauty, life and wonder of the ocean, as well as the increasing threats it faces.
But the film also provides hope and a glimpse at what a revived ocean could look like in just 50 years.
The film was released in cinemas to coincide with David Attenborough’s 99th birthday.
Keith Scholey is an Emmy and Bafta award-winning natural history and environmental filmmaker who has worked with Sir David for 44 years. Keith directed Ocean with David Attenborough and speaks with Susie.
