The UK has agreed to transfer sovereignty of the largely uninhabited Chagos archipelago to Mauritius. The islands have been known as the British Indian Ocean Territory since being administratively detached in 1965 from what was then the colony of Mauritius. Except for the US military base on Diego Garcia at the southern tip of the archipelago, the islands have been uninhabited since 1973.
As Mauritius takes back control, there are big environmental implications.
These 247,000 square miles (640,000km²) of remote seas include among the most pristine tropical coral reef ecosystems on our planet. Chagos is nearly three times the area of the British Isles. In 2010, it became the world’s largest marine protected area that bans any form of fishing.
