Sir David Attenborough has issued a powerful rallying cry to protect the oceans in a film released to coincide with his 99th birthday.
The new documentary, Ocean With David Attenborough, includes dramatic footage of the devastation fishing practices such as bottom trawling wreak on the seabed and its wildlife, as well as highlighting the wonder of natural habitats, from kelp forests to coral reefs, and the need to protect them.
