Great Barrier Reef: Half of natural wonder is ‘dead or dying’ and it is on the brink of extinction, scientists say.
Half of the Great Barrier Reef is “dead or dying” and almost all of it is on the brink of extinction, scientists have warned in one of the bleakest assessments of the health of the world's biggest living ecosystem.
Climate change is leading the reef to undergo a “significant” event that threatens its existence, according to Australian ministers.
Only seven per cent of the reef has escaped “bleaching”, which happens when the water warms and leads the coral to expel the algae that lives inside of it, turning it white. If temperatures don’t drop, then the coral will not be able to recover and it will die.
