Summary:
- Coral reefs around the world have reached a "tipping point" where more than half of the world's coral has been lost since the 1980s.
- The main causes of coral decline are climate change, overfishing, and pollution, which have led to increased ocean temperatures, ocean acidification, and other environmental stresses.
- Protecting and restoring coral reefs is crucial to maintain the biodiversity and ecosystem services they provide, such as supporting marine life, protecting coastlines, and providing resources for human communities.
