Coral Reefs Are Losing Ground
Coral reefs are called the rainforests of the oceans because they are home to more kinds of fish, plants, and microorganisms than any other part of the marine world. The coral reef is the result of years of accumulation of the calcium carbonate secreted by the coral animals that live on its surface. A coral reef can be hit by a hurricane and lose a substantial part of its structure, but it will slowly rebuild. However, the balance is shifting against coral reefs largely because of people's activities and we are losing reefs faster than they can rebuild.
