About Coral Reefs
Are they plants or animals? How long do they live? Why are factors like global warming and overfishing so dangerous for coral reefs?
Although they cover only two-tenths of one percent of the ocean floor, these complex tropical ecosystems rival the rainforests in terms of biodiversity, supporting nearly a quarter of all marine species. They provide food and income to millions of people worldwide, and they protect our coastal communities from damaging storms and tsunamis. Constructed by living organisms, coral reefs are home to some of the most fascinating plants and animals in the world. Learn more about these incredible ecosystems here.
