The Great Barrier Reef is dying at an unprecedented pace. “We are going to keep reporting decline and recording change on reefs and telling people what they already know about how corals die,” Professor Ainsworth said. All Rights Reserved. The world’s largest coral reef is in serious danger. If bleaching destroys the connectivity then its ability to recover will be severely diminished. The ripple effect could be significant. Unfortunately, the Great Barrier Reef hasn’t had a chance so far.
