Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species.  Coral reefs are currently suffering from rising sea temperatures caused by climate change.  Coral reefs are also critical in the carbon cycle of planet earth.  They absorb calcium ions and dissolved carbon dioxide from the water.  They turn it into calcium carbonate forming their hard skeletons.
