| Sumario: | Coral reefs have existed on the planet for approximately 450 million years. Geological evidence, as represented in the fossil record, shows that ancient coral reefs were as complex an ecosystem as modern day reefs. Present day reefs are considered one of the two most productive natural systems in the world, the other being the tropical rain forests. Both these systems are currently at risk as a result of excessive and negligent use. Coral reefs are increasing in economic value and must be protected. Understanding and care will ensure their survival. |
