Name Institution Date Negative Environmental Impact of Hydropower on Wildlife Dams have been in existence for a long time. Their primal purpose was to serve as irrigation and flood control. At the beginning of the 19th century, their role was altered to include the generation of hydroelectricity, and by the early 20th century dams had become the mainstay for generation of electricity…

She implies despite the positive benefits brought about by Hydro power, the environment suffers a great deal of its side effects, notably, extinction of some form of wildlife. With the emergence of Global warming, dams have received a lot of attention despite the fact that they generate huge quantities of electricity without really burning fossil fuels. In this context, multiple questions have been raised concerning the environmental effects of hydropower. Among them, Are dams carbon neutral? What of the energy used in the construction of Dams and the reservoir that are created behind them (deforestation and decomposition). Notably, endless questions have been raised over the impact of Hydropower on the surrounding environment and more particularly, its impact on wildlife. As opponents of hydropower indicate, it appears as if enough evidence has been found to discredit Hydropower as an efficient energy source. Having that in mind, the paper seeks to discuss the negative environmental effects posed by Hydropower with a view to elucidate on the destruction of wildlife habitats. In a study by FWEE on provision of balanced information for water as a renewable energy resource in the North West, it is indicated that, some specific impacts due to a hydroelectric power projects mainly depends on the following variables (FWEE 1). Firstly, the size and the flow rate, secondly, the climatic and habitat conditions, thirdly, design type and operation of the project. Additionally, the habitat and climatic conditions as well as, the project locations play a significant role. In terms of the project location, upstream or downstream location often comes in focus. This clearly reveals that the dynamics involved in hydropower generations affect various sectors that are directly or indirectly related to its production. McCully, in his article of big Dams big trouble, published by New internationalists, close to sixty percent of the world’s largest river system are mostly fragmented by numerous dams and considerable water withdrawals for irrigation purposes. This implies that the massive fragmentation of and replumbing of the world largest rivers has led to an increased loss of fresh water species. In this regard, close to a third of the world fresh water fish species have been reported as extinct, vulnerable or endangered. Additionally, IEA Hydropower Agreement on Hydropower and the environment: present context and the guidelines for future Action, indicates that construction of the reservoir increased the storage water, thus covering riparian areas stream banks (23). Following these, inundation occurs. A change in the habitat conditions leads to the emergence of a new equilibrium. While this is happening, different set of dynamics begin to affect how species grow feed, spawn and grow within these regions. Though a rise in water levels increase electricity production, the riparian zone is affected since some of the vegetation initially covered by water may never re-establish McCully further indicates that a significant but unknown number of , amphibians, shell fish, as well as plants and birds that depend on Fresh water ecosystems are on the verge of extinction or as such, at risk (620). He further points it out that Flooding from Dams has the potential to disrupt Wildlife

Wildlife Tourism Introduction The tourism industry has increasingly been a stronger contributor to economies worldwide. Directly, tourism is expected to contribute close to 3% of global output for 2011 and is expected to go up to over 4% by the year 2021. However, factoring in related economic activities by tourism, the industry further gives over 9% for 2011 which is expected to rise further to over 9.5% ten years after and still discounting inflationary effects.
The company mainly operates in Quebec and is responsible for supplying continuous electricity in the region. However, the surplus electricity is sold to the other suppliers in the US and various parts of Canada. Various external and internal factors have been affecting the Information Technology (IT) management at Hydro-Quebec.
Therefore, this study will analyze and discuss not only the market structure of UK’s energy industry but also some oligopolistic equilibrium models to discuss the best way in which these firms could maximize its profitability over its close competitors.
Changes that affect entire chromosomes or segments of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and alter the proteins made by those genes. Conditions caused by a change in the number or structure of chromosomes are known as chromosomal disorders (Lewontin, 1974).
The author states that the viewing of animals takes place in different locations; these include animals’ natural habitat or environment where they live. Tourism involves actions that are termed as non-consumptive, these include taking photographs, looking at the places and observing eating procedures.
In the year 2010, fossil fuel contributed to over 75% of world energy consumption. This translated to the increase of toxic substances in the atmosphere by the same percentage (Environmental Literacy Council, 2008). Its is therefore necessary to direct our
The mortality rate in some caves is reportedly above 90%. The once common brown bat, for instance, has suffered a catastrophic population decline and may become extinct in the next 20 years as a result of the white nose syndrome (WNS) (Cohn, 2008).
