Great Barrier Reef Dying, Suffering Worst Coral Bleaching Ever Recorded

Hot waters in 2016 contributed to the largest die-off of corals ever recorded on Australia’s Great Barrier Reef,researchers announced.
The most impacted zone stretches 700 kilometers (about 435 miles) of the northern area of the Great Barrier Reef, scientists say. That region lost an average of 67 percent of its shallow-water corals in less than a year.
