Warmer temperatures, along with overfishing, runoff, and dredging, have now killed off nearly 50 percent of the world’s coral reefs. The impact of the ongoing climate change, directly affecting coral reefs by an already measurable rise of sea water temperature, was manifested by the third global bleaching event in 2015/16. This event caused a mass die-off of corals. Coral Restoration Foundation (CRF) is the world’s largest non-profit marine-conservation organization dedicated to restoring coral reefs to a healthy state, in Florida and globally.
