About 70-90% of all existing coral reefs are expected to disappear in the next 20 years due to warming oceans, acidic water and pollution, said scientists from the University of Hawaii Manoa, who presented their findings Monday at an ocean sciences conference. Climate change could kill all of Earth’s coral reefs by 2100, scientists warn. A reef extinction could cause ecological collapse. And these devastating effects will ripple out into human societies – almost a billion people worldwide reely as a source of food protein.

Coral bleaching is a stress reaction caused when corals spend long periods in warmer than average water. If the coral polyps die starvation after bleaching, they will decay. The hard coral species will then leave behind their calcium carbonate skeletons, which will be taken over by algae, effectively blocking coral re-growth. Eventually, the coral skeletons will erode, causing the reef structure to collapse.
