All coral reefs in western Indian Ocean ‘at high risk of collapse in next 50 years’

Reefs from Seychelles to South Africa may become functionally extinct due to global heating and overfishing, study finds

All coral reefs in the western Indian Ocean are at high risk of collapse in the next 50 years due to global heating and overfishing, according to a new assessment.

From Seychelles to the Delagoa region off the coast of Mozambique and South Africa, the reef systems are at risk of becoming functionally extinct by the 2070s, with a huge loss of biodiversity, and threatening the livelihoods and food sources for hundreds of thousands of people.
