Tristan da Cunha

The British South Atlantic island of Tristan da Cunha has created the world's fourth-largest marine reserve and has banned deep-sea mining and fishing with beam trawls over an area of 627,000 km². This created the largest protected area in the Atlantic Ocean and the fourth largest in the world.

The protected area is part of the so-called blue belt, a protection program for British overseas territories, which the British government is funding with 27 million pounds (approx. 30 million euros). So far, a total of 11.1 million square kilometers have been protected - that is one percent of the world's ocean area.
