Marine sanctuary three times the size of the UK created in the Atlantic

The waters around a remote UK Overseas Territory in the Atlantic Ocean are to become one of the world’s largest marine sanctuaries to protect wildlife. The government of Tristan da Cunha, in the South Atlantic, has declared a 687,000 square kilometre (265,000 square mile) marine protection zone in the territory’s waters – an area almost three times the size of the UK.
