  • The Convention Concerning the Protection of the World Cultural and Natural Heritage is an international agreement that was adopted by the General Conference of UNESCO in 1972.

Coral Bleaching

  • Warmer water temperatures can result in coral bleaching. 
  • When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching.
  • When a coral bleaches, it is not dead. 
  • Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
