Continued from the first part...
Coral bleaching happens when polyps lose their zooxanthellae which is the plant that live inside their body.
The polyps turn white and can no longer continue building the reef. Storms and diseases cause some coral bleaching, but scientists think that the greenhouse effect which has turned the temperature up in the seas, caused the damage. Zooxanthellae cannot stay in a polyps body when the water gets too warm.
