Ms Ley said: “Climate change is the single biggest threat to all of the world’s reef ecosystems… and there are 83 natural World Heritage properties facing climate change threats so it’s not fair to simply single out Australia.”
But Australia has been battling to keep the Great Barrier Reef off the “in danger” list for years.
The reef is a huge tourist attraction that supports and creates thousands of jobs each year.
The reef is composed of 3,000 individual reef systems, 760 fringe reefs, 600 tropical islands, about 300 coral cays, and is the world’s largest living ecosystem.
They house a wide variety of marine life, plants, and animals, including sea turtles, reef fish, more than 100 species of sharks and rays, and 400 hard and soft corals.
