One of the greatest threats to coral reefs is human expansion and development. As development continues to alter the landscape, the amount of freshwater runoff increases. This runoff may carry large amounts of sediment from land-clearing areas, high levels of nutrients from agricultural areas or septic systems, as well as many pollutants such as petroleum products or insecticides. Whether it is direct sedimentation onto the reef or an increase in the turbidity of the water due to eutrophication, decreases in the amounts of light reaching corals may cause bleaching. In addition, increases in the amounts of nutrients enhance the growth of other reef organisms such as sponges which may outcompete the corals for space on crowded reefs.
