Protecting Coral Reefs

Coral reefs face many dangers. Diseases and strong storms can harm or destroy reefs. Pollution, very dirty water, changes in how salty the water is and water that is too warm can also harm reefs. Dangerus algae and crown-of-thorns starfish which eats corals(I guess that is the starfish that is destroying the Great Barrier Reef as most starfsh are ot a danger to coral reefs; as they feed on shellfish, plankton and sponges.), can wipe out reefs. People damage reefs with boats and by catching too many fish or breaking off bits and pieces of corals.
