Campaign to save oceans maps out global network of sanctuaries

Study creates blueprint to safeguard marine life and enable ocean recovery

Academics have mapped out a network of sanctuaries they say are required to save the world's oceans, protect wildlife and fight climate breakdown.

The study, ahead of a historic vote at the UN, sets out the first detailed plan of how countries can protect over a third of the world's oceans by 2030, a target scientists and policy makers say is crucial in order to safeguard marine ecosystems and help mitigate the impacts of a rapidly heating world.
