A mysteriously healthy patch of coral reefs in the Red Sea and Persian Gulf might provide scientists with ways to protect the rest of the reefs

In the past 20 years, nearly a third of the world's coral has been destroyed. Around 90 percent of the reefs off the coasts of Sri Lanka, Tanzania, Kenya, the Maldives and the Seychelles are at risk. If ocean temperatures rise by another 7ºF in the next three decades, as is predicted, 95 percent of the Great Barrier Reef will disappear. The primary cause of the die-off is coral bleaching. As temperatures rise, marine bacteria flourish and attack the algae that live symbiotically within every individual coral polyp.
