When people grab, kick, walk on, or collect coral, they also contribute to coral reef destruction. Human Run-off Fertilizers and sewage dumped into coastal waters encourage rapid algae growth which chokes coral polyps, cutting off their supply of light and oxygen. Over-fishing makes this problem even worse because the fish that would normally eat the algae have been captured and killed. Coral reefs are some of the most valuable and spectacular places on earth.
