Gulf Today Report
UNESCO's list of World Heritage sites included Australia’s Great Barrier Reef, but climate change and its adverse effects have left the reef's current status in discussion.
The reef was facing many other concerns over the years other than climate change, and that included security concerns, ecological issues etc.
As one of the largest living structures visible from space, the reef was added to the list of World Heritage sites listed under UNESCO in the year 1981.
