According to scientists, two consecutive years of coral bleaching has damaged two-thirds of Australia's Great Barrier Reef.
Aerial surveys showed that bleaching has affected about 1,500 km (900 miles) stretch of the reef.
In 2016, the bleaching, caused by a rise in water temperatures and the El Nino effects, damaged the northern third of the Reef, situated off the northeastern coast of Australia, while now the middle third has suffered the most severe bleaching in less than a year.
This year, 2017, we are seeing mass bleaching, even without the assistance of El Nino conditions.
