Worldwide coral reefs are being threatened by a range of human activities. Sedimentation, overfishing, global climate change, ship groundings, pathogens and pollution are some of the major human-related stressors impacting coral reefs. Land based sources of pollution can include both organic (e.g. PAHs, PCBs, pesticides) and inorganic (e.g. heavy metals) contaminants, all of which have the potential to impact the ecology of a coral reef ecosystem.
