Ban Coral Harvesting Entirely

Another NY Times science article talks about a group advising a 5 year ban on harvesting black coral from Hawaii.

A good idea, but here's a better one. Why don't we ban the harvesting of coral entirely? What possible good does coral do us? Pretty stuff in our fish tanks. This is like harvesting elephants for ivory. It's just a luxury good and one that any of us could live without. The world's coral reefs are under attack anyway for multiple reasons. If we eliminated every problem but that group of scuba divers who are irresponsible, we would still be denigrating this ecosystem. The last thing we need is to be harvesting the stuff for no reason that really serves humanity.
