Question 18GS3GS3
What are the key causes of marine pollution? Discuss its overall impact on the environment.
Main Body
5Release of Radioactive Waste: Has recently alleged by China & S Korea. Release of water ahead in Fukushima raising early concern. 6) Degradation of Mangroves: Mangroves act as natural filter for direction off by these protect marine ecosystem, but due continued degradation of mangrove → leads to marine pollution. 7) Spread of invasive species: due to transboundary shipment many new invasive species are introduced at various location → thus endangering the local species, eg: zebra mussel. 8) Increasing level of atmospheric carbon dioxide - leads to acidification of ocean waters → warming → ocean warming → damages biodiversity, coral bleaching. 9) Melting of glaciers due to global warming: Introduction of zombie virus → leads to threat to marine ecosystem, human based past → harming based past. 10) Overexploitation of fisheries: physical degradation of marine ecosystem.
11Release of heavy metals - biomagnitication. Steps taken to improve marine ecosystem: → United Nations Convention on Laws of the Sea, 1982: It governs rules for the use of ocean & their resources. → Part XI → International Seabed Authority: Regulates exploitation of minerals of the stated outside the countries exclusive economic territory. → Part XII - protection & preservation of marine environment. → MARPOL (Convention of Protocol) to control pollution from ship. → High Treaty: Seacraft: Yet to be ratified by India → for protection & preservation of ocean beyond EEL while safely exploring for minerals. Overall Impact of Marine pollution: → Heating of Ocean → overall heat content of ocean increases accelerated climate change and degraded biodiversity → More frequent cyclones & tsunamis → ingested by marine animals → loss of biodiversity, biomagnitication. → Thus it is high time to take decision steps to prevent further damage of protected the ocean.
