Scientists warn US coral reefs are on course to disappear within decadesUploader: Dogor 5 years ago Subscribe 5
Because they are so diverse, coral reefs are often called the rainforests of the sea. Deep-sea corals do not have the same algae and do not need sunlight or warm water to survive, but they also grow very slowly. Coral reefs are the most diverse of all marine ecosystems. Check out this video of Smithsonian scientists monitoring Acroporid populations near Carrie Bow. Recent studies have shown a reduction in individual coral growth in the Great Barrier Reef, southern Thailand, and the central Red Sea of between 13 percent and to 24 percent over the last few decades. This is called fragmentation, which can occur as a result of a disturbance such as a storm or being hit by fishing equipment.
