This chapter explores the regulation of land-based pollution, which presents the most serious threat to marine ecology. Pollutants resulting from land-based activities include sewage, industrial discharges, and agricultural run-off. Major contaminants include plastic litter, nutrients, heavy metals, sediments, oil, and radioactive wastes. Some of the contaminants produce eutrophication and oxygen depletion, resulting in loss of marine life and biological diversity. Other substances are directly toxic to humans. In spite of these hazards the regulation of land-based marine pollution at the global level remains a weak one-in the sense that attempts to address land-based marine pollution have been made solely in the form of non-binding documents.
