Large Study Shows Pollution Impact On Coral Reefs, and Offers Solution A three-...year, controlled exposure of corals to elevated levels of nitrogen and phosphorus pollution from sewage, agricultural practices or other sources at a study site in the Florida Keys, done from 2009-12, showed that the prevalence of disease doubled and the amount of coral bleaching, an early sign of stress, more than tripled. However, the study also found that once the injection of pollutants was stopped, the corals were able to recover in a surprisingly short time. http://www.sciencedaily.com/releases/2013/11/131126092656.htm
