What are the effects of coral reef degradation?
As waters rapidly warm, corals lose the components that give them color and help them produce food, a process called bleaching. That slows their growth and makes them vulnerable to algae, disease, and death. Increased ocean acidification caused by the absorption of carbon dioxide causes bleaching, too.
