2nd Year Of Mass Coral Bleaching | Great Barrier Reef May Not Recover

Australia's Great Barrier Reef has faced a second mass coral bleaching event in just 12 months, which scientists fear could kill part of the world's largest living structure.
It will take up to nine months to find out how many of the bleached corals end up dying, but Hughes fears that the central reef may have been nearly as badly damaged this year as the northern part was last year, when 67 per cent of the corals were lost there.
It is a loss that under normal circumstances would take a decade to recover from. But now that bleaching is happening every year or every other year in some areas, recovery will be difficult if not impossible.
