There has been a 44% decline over the last 20 years in the Florida Keys, and up to 80% in the Caribbean alone.

Coral is very sensitive to changes in seawater. It requires the temperature is moderate but clean without sewage. As long as there is enough time, coral reefs can naturally recover a little natural damage, and sometimes even make the coral reef biological richer. Human activities on coral can cause the pressure of the reef so long and extensive. These pressures may be generated on coral reefs forever. The method of restoring the damage even of coral death is researched into four parts: coral Introduction, what is the coral bleaching phenomenon, causing bleaching, and the strategy to save coral bleaching.
