Reefs will be dead within 30 years, expert warns

THE world’s reefs, including Australia’s Great Barrier Reef, will be dead within 30 years unless human activity changes quickly, a leading researcher says.
Addressing the 11th international River symposium in Brisbane, Ove Hoegh-Guldberg said it was crunch time for the world’s reefs.

“Let’s say we delay another 10 years on having stern actions on emissions at a global level, we will not have coral reefs in about 30 to 50 years,” he said.
