Third of Great Barrier Reef coral killed by bleaching
Around 35 percent of the coral in northern and central sections of the Great Barrier Reef is dead or dying, as per a recent survey.
Further, a research says that as much as one third of the coral on the northern and central Great Barrier Reef in Australia was destroyed by mass bleaching.
Terry Hughes, a professor with James Cook University, in Queensland, said on Monday: "This year is the third time in 18 years that the Great Barrier Reef has experienced mass bleaching due to global warming, and the current event is much more extreme than we have measured before,"
Bleaching occurs when the water is too warm, forcing coral to expel living algae and causing it to calcify and turn white. Mildly bleached coral can recover if the temperature drops, otherwise it may die.
