Coral reefs face numerous threats. Weather-related damage to reefs occurs frequently. Large and powerful waves from hurricanes and cyclones can break apart or flatten large coral heads, scattering their fragments. A single storm seldom kills off an entire colony, but slow-growing corals may be overgrown by algae before they can recover.

2008年3月31日 · Perhaps corals' greatest enemy, however, is humans. Not only are humans likely responsible to some extent for the rising water temperatures that cause coral bleaching, but fishing methods, pollution and even seemingly unrelated actions like deforestation harm coral.
