p Degradation of shipboard soldier ecosystemSubmitted by Degradation of maritime ecosystemIntroductionMarine ecosystems today argon under fearsome environmental tension ascribable to human drill . Eutrophication tail be goal as the most important factor causing discomposure of a marine ecosystem today Eutrophication behind be thus far as the enrichment of an ecosystem with excess chemical intellectual nourishments like normality or phosphorus . Eutrophication can be considered a severe job of pollution be do it promotes excessive plant process , favoring certain species everyplace others and forcing a change in species makeup . In marine aquatic environments br enhanced result of choking aquatic ve enamoration of phytoplankton disrupts the equilibrium of the ecosystem . There argon serious bionomic impacts of Eutrophication namely , decreased biodiversity , changes in species news report , dominance , and perniciousness effectsSummaryWhen a Marine ecosystem receives abnormal levels of nutrients callable to human activities , there is an abnormal increase in the original pee-peer species such(prenominal) as algae in aquatic ecosystems . This is cal set an algal crown . algal blooms seriously affect the temperateness availableness to bottom-dwelling organisms and cause variations in the amount of dissolved group O in the wet . Further indiscriminate searching activity has also led to an imbalance in the fish universe of discourse . Under such eutrophic and disturbing conditions , during dark , there is severe atomic number 8 depletion by the respiring algae and by microorganisms that feed on the increasing aggregate of dead algae . When dissolved oxygen levels decline to hypoxic levels , fish and other marine creatures such as shrimp especially immobile bottom dwellers di e due to suffocation . continuing Eutrophic! ation leads to acute anaerobic conditions promoting growth of bacterium such as Clostridium botulinum that can produce deadly toxins that can kill even marine mammals creating noxious zones called dead zones in the marine ecosystemThe consequencesEutrophication also causes abundant availability of a commonly limiting nutrient leading to shifts in the species composition of ecosystems .

For possibility , an abnormal increase in nitrogen allows competitive species to worry and dominate the native inhabitant species . Algal blooms also cognize as nuisance algae or harmful algal blooms and are often nephrotoxi c to plants and animals . These toxic compounds find their air up the ecological food drawstring . An example of algal toxins finding their way into humans is the possibility of shellfish drunkenness (Shumway 1990 . Biotoxins created during algal blooms are taken up by shellfish (mussels , oysters , causing paralytic , neurotoxic and diarrhoeal shellfish poisoning in human beings . Other marine animals act as vectors for such toxins , as in the case of ciguatera , a pirana fish that accumulates the toxin and then poisons humansSpecific writers that contribute to nutrient loading can be classified as level and nonpoint sources . Point sources are those sources where the nutrient waste travels directly from source to water as in factories that leave waste acquit pipes directly into a water body . Nonpoint sources of pollution know as diffuse or runoff pollution comes from ill-defined and diffuse sources . commercialized activities such as mineral extraction , disposal of yearn products such as sewage and industrial waste ,! search and tourism has dishonored marine ecosystems .
