The magnitude and threat of marine and estuarine pollution is gradually increasing with the growing use of sea for commerce, mineral and oil extraction, nuclear weapon testing and recreational activities. The other reasons are the river run-off carrying various categories of pollutants from the cities, towns and agricultural lands, atmospheric deposition, oil spills etc. The effects of marine and estuarine pollution are severe. Apart from bioaccumulation and biomagnification of conservative pollutants across the food chains, loss of sensitive species, dominance of opportunistic species create a massive imbalance in the community structure of marine and estuarine environments. Anthropogenic pollution may reduce biodiversity and productivity of marine ecosystems, resulting in reduction and depletion of sea food resources. Majority of the anthropogenic and industrial pollution ends up in the ocean via the conveyer system of estuaries.
It is often difficult to regulate marine and estuarine pollution because the arms of marine and estuarine pollution spread over international barriers thus making regulations, hard to create as well as enforce without appropriate awareness of marine pollution and international participation. The necessary global will to effectively address the issues may prove inadequate. Information on the sources and harmful effects of marine and estuarine pollution need to become a part of public domain and awareness. Also quality research and documentation are required on continuous basis to fully establish the current scope of the issues. Policies need to be implemented both at national and international levels on the basis of the outputs of these researches.
