1. Introduction:
In the following research paper, the parameters of how eutrophication develops will be discussed to acquire an understanding of this phenomenon. In addition, preventative and control methods will be looked at in order to devise a plan of action against eutrophication.

In an aquatic ecosystem most of the nutrients are well balanced with the biodiversity of organisms. [FIND DISCOURSE MARKER TO ADD TWO SENTENCES] These aquatic ecosystems become disrupted when eutrophication (the presence of excessive and unwanted nutrients), occurs. Nutrients from agricultural, industrial and urban areas enter a drainage basin (streams, rivers, lakes, dams and ultimately, the ocean) by means of run-off and groundwater. Certain organisms; for example, phytoplankton and algae, benefit from these nutrients which causes them to reproduce faster and amalgamate, forming a dense layer on the surface of the water. As a result, sunlight and oxygen cannot enter the water, causing extremely high carbon dioxide concentration levels and very low oxygen concentration levels. Due to a lack of oxygen, aerobic organisms experience hypoxia or suffocation and die.

According to Setmire et al., (2000) there is a misconception when it comes to the toxicity of a body of water and eutrophication. The increase of toxins and eutrophication in water affects the quality of the …show more content…

Natural eutrophication occurs when a body of water builds up nutrients over a long period of time, enabling it to sustain and support multiple living organisms. Algae then starts to form, damaging the ecosystem and decreasing the quality of the water. Cultural eutrophication; on the other hand, is caused purely by external human interference; such as, domestic and industrial waste being dumped into rivers of lakes and uprooting trees making the soil dry and loose, causing an excess of nutrients being run-off into drainage
