The Great Barrier Reef, considered one of the seven natural wonders of the world and a biodiversity hotspot, is located in Australia. Similar to other coral reefs, it is experiencing degradation due to ocean acidification.
In the world's largest coral reef ecosystem, Australia's Great Barrier Reef, bleaching affected 90% of the coral assessed in 2022. The Florida Coral Reef , the third-largest, experienced ...
