What´S Eutrophication? Essay

668 words - 3 pages

Eutrophication is the ecosystem response to an excessive richness of nutrients in an aquatic ecosystem. Normally eutrophication is a non-harmful, natural process that occurs when a body of water is aging. The natural cause of eutrophication is the run-off of nutrients from nearby soil and erosion. However a different type of eutrophication is human-caused which accelerates the aging process and creates environmental issues. When there is an excessive richness of nutrients in a body of water, algae feeds off of these nutrients and creates an algal bloom. Algal blooms are harmful because when they die, a lot of oxygen is used to decompose the remains. This causes hypoxia and sometimes, ...view middle of the document...

Most of these people care more about their profit than keeping the earth clean and saving aquatic lifeforms. When they need to get rid of their wastes, they taint the bodies of water by dumping the wastes in it. Additionally, this kills the fish that live near the factories. Another group of people that get rid of their wastes using eutrophication is farmers. However, most farmers do not know that they are harming the aquatic ecosystem by doing this. This is one reason why awareness of eutrophication should be raised, which will be covered later on.
Eutrophication severely affects local and global health. One thing it does is it increases phytoplankton biomass and the growth of rooted plants such as reeds. When there is an increase in phytoplankton biomass, it is evidence that eutrophication is taking place. Also, the growth of rooted plants may impede water flow and the movement of boats. Another way that eutrophication affects local and global health is by increasing the rate of sedimentation. When there are more sediments floating or suspended...

To start off, understanding the greenhouse effect and how human activity influences its effectiveness is crucial. S.

The Salton Sea

5525 words - 22 pages contributors Eutrophication is an immense problem at the Salton Sea. Eutrophication is a naturally occurring process , and it happens as lakes age and slowly gain more nutrients. In fact, there are 13 tons of nitrogen in addition to various pesticides and other organic phosphate pesticides found in the water of the Salton Sea. These nutrients allow the food web to become larger, supply more food for the fish and in turn changes the lake�s

Phosphorus contamination can have a long-term effect, as phosphorus accumulates into sediments derived from soil erosion. This "dormant" form of pollution may be released when floods or storms occur. Figure 2 illustrates what happens when excess phosphorus is leached into surface waters. Figure 2: Illustration of Eutrophication

So the key question is what is causing this increase in jellyfish population? There are a few theories as to why there has been an increase in the number of jellyfish. One contributing factor is believed to be from the result of dead zones. Dead zones are caused by a type of pollution know as Eutrophication, in

Marine Contamination and Pollution

1110 words - 4 pages . When raw sewage is dumped into an area without strong currents to disperse it, the oxygen is likely to be used up. When this happens, the only form of decomposition that can take place is anaerobic which takes a very long time. This process is called eutrophication (Clark 5). When nutrient rich sewage enters the ocean, an extreme overgrowth of toxic phytoplankton. This process causes what is known as red-tides that kill many forms of marine
