Man-made environment issue- Eutrophication EssayEutrophication is the ecosystem response to the addition of dyed or natural substances to an aquatic system. (Schindler, David and Vallentyne, John R. 2004)Most people don t really know more or less it, so Im writing this essay to tell some facts rough two major(ip) shake ups, the bad operation in my country China and the prevention and reversal and how undersurface the algae be employ to make more benefit to the world and people who live on it. The two major ca usages of eutrophication are excess nitrates and excess phosphates in weewee. (e-How Jul 05, 2012)Many farmers use fertilizers to make their plants grow better, moreover one of the about frequently-used fertilizers is the fertilizer which contain nitrates and phosphates. Once fertilizer is applied, the nitrates, which are water soluble, will leach into groundwater or choke and end up in surface runoff. Phosphates will adhere to soil articles, and often accumula te in soil and erode, along with soil, into aquatic environments. ( Smith, V. H. Tilman, G. D. Nekola, J. C. 1999. ) Meanwhile, nitrates can alike vaporize into the atmosphere, where they become a major ascendent of acid rain.When the raindrops drop into lakes or rivers and streams, there are nitrates that come into water and cause the eutrophication. The bad effect of eutrophication in China is really serious. One of the most famous ones is the Tai River cyan algae in 2007. Because of the eruption of blue-green algae, the water cant be used at all. It smells like something is befitting putrid. Also some algal blooms are toxic to plants and animals. It has affected the citizens lives they can just make whoopie and use the water which was brought in shops.The urgent implore of the water has caused the price of the water to became more and more expensive. (Face to the Tai River blue-green algae 2007) It has not only brought people a jalopy of inconvenience but it also causes ecological consequences. The general types of ecological consequences include reduction in biodiversity, die-off of certain organisms, reduction in visibility and mobility functions due to biotic overgrowth. (Eutrophication December 18, 2007) Because it causes a lot of biont to die, it breaks the equaliser of the natural world.Once the balance is broke, itll take a lot of time and plenty of human interference to fix it. In addition, it also affects the pocketbook of fishermen. There was less fish so fishermen could not catch many fish. (Face to the Tai River blue-green algae 2007) Even though eutrophication is just like an evil, there are still some ship canal to make it better. First of all, people can solve it by using biont that can remove or occupy the nitrates or algae. One proposed solution to eutrophication in estuaries is to restore shellfish populations, such as oysters. pull together reefs remove nitrogen from the water column and filter out suspended solids, subsequent ly reducing the likelihood or extent of harmful algal blooms or anoxic conditions. (Kroeger, Timm, 2012) And some plants, such as water hyacinth, Alternanthera sessilis, Zizania aquatica and plants like them are also helpful. ( No data,2008). The second one is a future tense work minimizing nonpoint pollution. People can make riparian buffer zones which are interfaces between a flux body of water and land. Creating riparian buffer zones nearby farms and roads is an efficient way to manage the eutrophication chore goes further.( Angold P. G. 1997) At the mean time, government can manage this problem by promulgating policy. The policy can be broken into four major sectors technologies, public participation, economic instruments, and cooperation. Technologies include all kinds of technologies that can prevent the eutrophication or can make it within a region. (Oglesby, R. T. and Edmondson, W. T. 1966. ) For example, the treatment of sewage is one of them. Public participation is use d to make sure people do something to help reverse the eutrophication so that the policy will be effective.The economic instruments are used to give incentives to those who are eco-friendly. (Planning and Management of Lakes and Reservoirs An Integrated Approach to Eutrophication. 2000) The cooperation between divers(prenominal) organizations is really necessary to prevent it spreading further. Lastly, sponsoring people to use algae is also a entire idea. China is a undecomposed example. The supply of crabs in China is always less than demand because Chinese love eating crabs. But the same crabs in Germany were so much that cause a lot of problems.The reason is Chinese eat them but German dont eat them. This means Chinese know how to use them, but Germans dont. However, how to use eutrophication? Ill talk about it in next paragraph. Although there are lots of bad effects of eutrophication, it is also possible to use the algae. First, they are used as fertilizers, soil conditione rs and are a source of livestock feed. People can also eat them. It is a complete protein with essential amino acids and it contains high amounts of simple and complex carbohydrates which go away the body with a source of additional fuel. (Uses of algae as Energy source, Fertilizer, 2013) From this we can see, the algae not only can be eaten but it also has a high level of nutrition. They are good for humans, animals and land. As they are crude, it wont hurt the environment and they dont use a lot of energy. As a result, the eutrophication also has a good aspect. To conclude, although there are a lot of causes of eutrophication, there are still ways to solve the problem. By these solutions, people can be successes in managing the eutrophication and even use it as a kind of resource.This can be helpful to the short of resources and the environment. At last, I hope after reading my essay, you can learn more about eutrophication Reference count Angold P. G. (1997).
