The World’s 10 Largest Coral Reefs

Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. These corals are unable to move and clusters with other corals so they form colonies. Coral reefs vary in size, type and location and they are very sensitive organisms. They want clear and hot waters. That’s why all coral reefs are located in the tropical places.
Today coral reefs are endangered by human. The greatest treat are the fishermen. Many coral reefs in South China Sea are endangered and this has to stop. Look at these great photos of the 10 largest coral reefs and lets increase the awareness to help coral reefs.
