--Curb you CO2 emissions:
Much of coral reef destruction is due to bleaching, usually caused by an increase in ocean temperatures
WHAT CAN BE DONE?
--Do not purchase tropical fish:
The aquarium fish industry uses coral reefs as a source for many of the fish that are available in pet stores
--Do not patronize resorts built near coral reefs:
Runoff from costal construction and houses pollutes the water around reefs and can choke them out, causing bleaching
