The Great Barrier Reef can be classified as a vulnerable site
It proved that the waters began to rise in late December and that the three main areas where the barrier is located were affected by the phenomenon, which led to a change in color due to the expulsion of algae, which gives the coral its bright colour. Bleached corals survive and may recover if conditions improve, but “Highly bleached corals have higher mortality rates”explains the study, the first version of which was published in March.
This report was published ten days before the Australian federal election on May 21, in which government policy on climate change will be at the heart of the issues.
in june, UNESCO must decide whether to include the Great Barrier Reef on its list of ‘endangered’ sites. Australia launched a $1 billion conservation plan “Reef 2050” after the United Nations threatened in 2015 to shut down the site.
