Scientists have named three "hot spots" for the catastrophic extinction of corals

A survey of coral reefs in 87 countries found that reef species diversity has declined by more than 60%, and

The total coverage of reefs has decreased by about half, while the deteriorating state of ecosystems has also affected the people who liveThree "hot spots" were hit the hardest: the waters of Indonesia, the Caribbean Sea and the South Pacific Ocean. Climate change in the future will accelerate many times overdegradation of these ecosystems and will lead to disaster.

The results of the work were published in the journal "One Earth".

The ability of coral reefs to maintainthe ecosystem fell by about 50%. This suggests the need to protect corals not only in certain regions of the Earth, but throughout the world as a whole, since the survival of these ecosystems depends on the life of a huge number of people.

William Cheung, one of the study's authors, is a professor at the University of British Columbia in Canada 

The authors of the work are confident that this century  a fifth of all coral reefs, including the Great Barrier Reef, will completely disappear.Not only is warming the problem, but corals are threatened by new infections and parasites that are spreading across the Pacific and Indian Oceans.
