Coral Reefs
...
Beneath the ocean waters is where coral reef is found. Coral reefs are large underwater formations that are made up of the skeletons of marine invertebrates called coral, as well as algae. There are many different species of coral in oceans all over the world.
Coral plays a critical role in the ocean because many species depend on coral for survival. Coral reefs help to shield coastal populations from erosion, storms, and waves. Millions of species in the ocean also depend of coral for food and shelter. But coral is in danger due to many threats including pollution and certain fishing practices. When reefs are healthy, the ocean is healthy. For this reason, many efforts have been established in order to preserve these resources for future generations.
