Coral reefs and other marine life in the Florida Keys National Marine sanctuary are threatened by human activities.
Population and urban development
Population growth and urban development are some of the greatest threats to coral reefs. Development activities cause erosion, resulting in the run off of sediments that eventually reach the coral reefs.
