*Reefs are very stable, and provide a protective barrier around many islands and coasts. Without the reefs these islands and coasts will erode away into the ocean. *It is important to protect the reefs we have today, because they can't be replaced. Reefs are formed very slowly by tiny animals called coral.Each animal is tinier than your pinky nail, and grows very slowly, only about 1 centimeter a year.hey are important to the biosphere because they provide a home for the animals and microscopic beings that inhabit the reefs. This is why we should work our hardest to suppor â¦ t and save the reefs. READING IS IMPORTANT.
