  • Worldwide coral reef death is blamed on global warming.
  • Coral reef bleaching is the reduction in photosynthetic pigment in corals. It is caused by several environmental factors including sea temperature, solar irradiance among others.
  • Coral bleaching causes the destruction of the main reef tracts and the extinction of many coral species.
  • Ocean pollution poisons corals.
  • Pollution takes many forms such as oil slicks, pesticides, heavy metals, and garbage.
  • Coastal development ravages reefs
