The Pros And Cons Of Eutrophication
1114 Words5 Pages
Eutrophication is an extreme wealth of supplements in a lake or different waterways. Eutrophication happens when the spillover of residue from and land go into a waterway. At the point when this happens, a thick development of vegetation happens, which exhausts the huge oxygen request (BOD), which means the oxygen that is accessible to amphibian life is no more.
Eutrophication might likewise be realized by the seepage of sewage, mechanical squanders, or cleansers into a waterway. As the stuffed plants cease to exist, the dead and rotting vegetation exhausts the lake 's oxygen supply. This, thus, prompts the passing of fish in the lake. The amassed dead plant and creature material in the end changes a profound lake to a shallow one. The shallow lake then turns into a marsh, lastly it gets to be dry area.

The Eutrophication test determines the amount of nutrients there are in a stream, creek, or most bodies of water. When we did the Eutrophication test we got a lot of low numbers. For the Phosphate test they were mostly a 0 with a .1. When we did the nitrate test we got .25, .75, 1, 1.2, 1.5, 1.3, and a .9. for the dissolved oxygen tests they were all mostly high results.

One issue found is the creation of smelly phytoplankton that makes murky unclear waters along with aquatic impurities. Moreover, the reduction of growth due to poor light conditions and dying plants make it difficult for predatory fish to hunt leading to overpopulation. (Chislock, 2013) Eutrophication can be found in many of our water resources such as ponds, estuaries, and bays. One region with high areas with eutrophication is in a lake shared by Kisumu, Kenya and Kampala, Uganda.

Eutrophication is the excessive nutrients in a lake or body of water, frequently due to runoff from the land, which causes a dense growth of a plant life and death of animal life from lack of oxygen. We tested for phosphate, nitrate, and dissolved oxygen. Phosphates and Nitrates are found in fertilizers, laundry detergents, and sewage treatments. Dissolved oxygen is microscopic bubbles of gaseous oxygen that are mixed in water and aailable to aquatic organisms for respiration. We found that there was a phosphate average of 0.1 parts per million (ppm).

All organisms need oxygen to survive and when their is not enough oxygen, it leaves plants and animals to die. The area of water where there is a low count of oxygen are often called a dead zones. Also, an increase of the pH level in the water can be created because of algae blooms. The toxic killing algae can make humans sick. For the aquatic animals, these toxins attack mainly the organisms liver and nervous system (Nitrogen and

At this point the pros and cons of organic gardening are fairly widespread, however for many beginner gardeners it can be a tough process to get into. More vigorous gardening is required, with a reduced reliance on chemical sprays or other similar product. Here some of the essential things a beginner gardener should know before starting organic gardening. Maintaining soil quality the main focal point of this gardening process is maintaining soil quality. The reason soil is so important to the organic gardening process is that the soil is the life force of the garden.

Assignment: Coastal management • Explain what is coastal management • Discuss the types of coastal management and when they are used • The pros and cons of the types of coastal management Word limit is 2500 including references. Why is it important to defend the coast? Coastlines today, tend to be very heavily populated areas that are of high economic value due to tourism as well as key access point to ocean fisheries resources and sea transport routes. However, coastlines are particularly prone to flooding, whereby these fragile ecosystems take a long time to recover if they are degraded or destroyed.

Eutrophication is defined as “the process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates” (Eutrophication, 2015). Furthermore, scientists have determined a number of human activities that may contribute to eutrophication in bodies of water such as the Mississippi River and Gulf of Mexico (Eutrophication in the Gulf of Mexico: How Midwestern Farming Practices are Creating a Dead Zone, 2012). For example, prior to the 1950’s when rivers are channelized for navigation and flood control purposes (Eutrophication in the Gulf of Mexico…, 2012). A second illustration would be “landscape alteration”, which consists of deforestation and agricultural drainage that alter nature’s runoff buffers and results in additional nutrients entering the water supply (Eutrophication in the Gulf of Mexico…, 2012). A third human activity is agriculture, which often requires the usage of chemical fertilizers that leads directly to increased levels of nutrients in bodies of water.

Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.

It is well known that eutrophication occurs when excess nutrients are added to a body of water and primary productivity is increased. However, the scientific paper, Aquatic eutrophication promotes pathogenic infection in amphibians, puts a direct focus on a specific parasite, Ribeiroia ondatra, and seeks to give evidence that the onset of eutrophication is the driving factor allowing the parasite to disrupt amphibian development. The authors set-out with the goal to provide evidence that eutrophication leads to an increase in the number of snails as intermediate hosts for the parasite, while also increasing the snail size and reducing snail mortality; providing more candidates to pass the parasite onto amphibians to inhibit their development. This research, as stated in the paper, looks to identify eutrophication as the factor promoting this pathogenic infection in the amphibians. Although some have tried to pinpoint this already, no evidence prior had been provided to

Urie Bronfenbrenner was a Russian born American, he was born on 29 April 1917 and died on 25 September 2005. Urie was a developmental psychologist and was very well known for his ecological systems theory on child’s development. This theory basically states that there are different levels that influence a child’s development. Each level of this system has its own advantages and disadvantages and each level is of the same importance as the other.
