“Monitoring data from 105 stations in the Florida Keys has revealed a 44 percent decline in coral cover from 1996-2005,” reports the Florida Department of Environmental Protection. In addition to the devastating effects of fishing and marine tourism, Florida’s reefs suffer the consequences of that state’s unsustainable population growth. Large coastal infrastructure projects, such as the installation of pipes, cables and wastewater outfalls for public utilities, have contributed to shoreline erosion and damaged coral habitat through water pollution. “Beach nourishment projects, in which large volumes of sand are re-located from offshore to onshore, can cause severe impacts to reefs. Coral reef organisms may be smothered by sediments and reduced water clarity deprives corals of the light they require for photosynthesis by their symbiotic algae,” explains the Florida DEP.
