Eutrophication

The Negative Condition of the Great Lakes By: Spenser Larson I am Spenser Larson from Chicago, Illinois . I am qualified to write this editorial because I graduated for the University of Stanford in California. I majored in Environmental Science while being the top of my class. I am currently a scientist for the United States Government. I am worried about the pollution in the great lakes because animals such as baby bird have been known to have deformations because of the cancer their mothers…

Water, something people can’t live without with. However, water quality has always been an issue in Canada. People may not really notice it since in households, people can drink the water from the hose, or by boiling it if they are concerned about it. For example, due to population increase, it increases the demands for agriculture, manufacturing, energy and transportation. This also leads to pollution of chemicals into rivers and lakes in Canada. These pollutants threaten the water quality, and…

The great lakes have experienced a rise in the number of harmful Alga blooms (NOAA, n.d.). Quagga and zebra increase the amount of sunlight penetrating at the bottom of the lake which promotes this growth (NOAA, n.d.). Cladophora is responsible for one particular alga bloom which grows at the bottom of the lake (NOAA, n.d.). Large piles of Cladophora can be found washed up on the shores of beaches after it dies (NOAA, n.d.). Harmful bacteria are trapped within these piles which can harm humans…

Nitrogen and phosphorus are the major limiting nutrient elements in a variety of aquatic ecosystems and are altered by anthropogenic activities; such as row crops, feed lots, and humans (Elser et al. 2007). Larger inputs of nitrogen cause an abundance of phytoplankton and macrophyte production (Ferree and Shannon 2001).The purpose of this study was to examine nitrogen and phosphorus levels at Ada Hayden Lake in the comparative context of their effect on phytoplankton abundance as well as…

The Hydra You have just taken a hike through the woods and then you discover a salt water lake. Seeing a strange portal, curious, you swim towards it. You go on to the miniscule island that the portal is on. As you start to get near the portal a thick fog starts to form and you can’t see anything. The ground starts to tremble at your feet as a gigantic figure rises from the shadows. As the gigantic shadow looms over you it starts to stomp towards you, you are about to fall down as it gets…

The conodoguinet creek was not polluted. The creek was not polluted Because there was a little bit of algae and there was a bunch of animals living in the creek. The creek was a safe place for the animals living in the creek. The water speed of the creek was normal not to fast and not to slow. That's why I think the creek is not polluted. There was some nitrate in the creek. The nitrate absorbs oxygen and that's not good for the animals. The nitrate is actually dangerous to the creek and the…

The most likely causes for the dead zone in the Great Lakes are the amount of phosphorus nitrogen and fertilizer running off into the lake. When the lake becomes rich in these nutrients and you add warmer temperatures into the equation you can expect an algal bloom. Once the bloom dies the decomposition depletes much of the oxygen in the water which is severe because of the size of the algal bloom. This coupled with things such as low water inflow and temperature of water are the most popularly…

The pollution of Lake Erie is algae. If you don't know what algae does to the lakes then keep on reading because it’s very harmful. People have to wait till they can drink the water. Because algae has lots of bad chemicals and bacteria. There’s a lot of people that help with the clean up. The lakes can be called “Dead lake” because its very dirty and not in good use. Fertilizer is a big problem because farmers use it alot and when it rains the fertilizer gets in the drains and into the lakes.…

Committee: Representative of Agriculture Topic: Lake Erie’s Toxic Algal Bloom Name: Violet Landrum “Nobody adores fertilizer. Nobody devotes their life to fertilizer (unless they own a fertilizer company). But, you need it to grow the crops. The land is arid and dry without it, and trying to grow things is likely to be futile.” - Shellen Lubin. According to a paper written in Science, the ocean has lost roughly 77 billion tons of oxygen in the last 50 years, being up to nearly 2% of its waters…

1 The biotic factors of the experiment are the fish, plants, killifish, and heavy vegetation. The abiotic factors are the cages and the stream movement. Fish in the vegetation-heavy enclosures died. When oxygen is consumed by vegetation, fish become stressed out. This stress causes them to die as they do not eat in environments with dense vegetation. In the researcher’s experiment, some enclosures lacked vegetation. The enclosures that were not vegetation-heavy did not stress the fish out. The…
