  • carbon dioxide sink
  • atmospheric changes, global warming
  • ultraviolet light,
  • ocean acidification

This is a worrisome fact, that 19 % of the reefs are completely destroyed and a further 15% is likely to be lost over the next 10–20 years. Only 46 % of the world’ s reefs are in a good condition.

The reef destruction is the worst in the Philippines, where over 80 % of the corals are endangered and only 5 % is in good condition.

By the 2030s, 90% of reefs are expected to be at risk from both human activities and climate change.

By 2050, all coral reefs will be in danger.
