爱尔兰动物科学论文代写:野生动物

环境作为一种有限的资源的重要性是经济学相对较新的构想。只有在布伦特兰委员会于1987年发布其报告后,才认识到环境的重要性及其保护。在一个经济体中,环境通常服务于四个主要目的:提供基本的生命保障,原材料来源,废物收集和提供舒适的服务(Perman ,Ma,McGilvary,&Common,2003)。

野生动物作为环境的一部分,有几个目的。它是非素食者的食物来源,它们的身体部位如象牙,皮肤或牛角以巨大的价格出售,但最重要的是野生动物作为娱乐服务提供者的主要形式。野生动物在当地的存在鼓励旅游业,从而为当地居民带来经济和就业的资金。因此保护野生动物是非常重要的。

野生动物的灭绝有许多原因,但基本上这些原因主要是人造的。诚然,自然原因导致物种灭绝,但这些只发生在地质时间表上。由于地球整体气候条件的变化,猛犸象物种灭绝的例子是常见的。然而,最近对野生动植物危害的担忧,是由于人们过度放纵(鲁文,布鲁代尔,内米洛夫,贝兰德,多林克,格兰特,2006)而导致的鲁莽(不)经济增长。人类活动已经改变了物种的全球灭绝率,提高了三到四倍(Polasky,Doremus,&Rettig,1997)。

本文试图找出为什么在加拿大保护野生动物很困难。论文分为两部分:第二部分介绍手头的问题背景,第三部分简要回顾现有的文献,第三节提出方法论,第四节进行数据分析,第五节进行统计分析的回归模型,第六节结束。

The importance of environment as a limited resource has been a relatively recent construct in economics. The importance of environment and its protection was realized only after the Bruntland Commission released its report in 1987. Environment typically serves four major purposes in an economy: provision of basic life support, source of raw materials, waste sink and provision of amenity services (Perman, Ma, McGilvary, & Common, 2003).

Wildlife, being a part of the environment, serves several purposes. It is a source of food for the non-vegetarians, their body parts like tusks, skin or horns are sold at huge prices but most importantly, the wildlife serves as a major form of recreational service provider. The presence of wildlife in a locality encourages tourism which in turn brings money to the economy and employment to the local residents. Thus preservation of the wildlife is very important.

Extinction of the wildlife has many reasons but essentially these reasons are largely man-made. True that natural reasons lead to extinction of species but these occur only in geological timelines. The examples of extinction of species like mammoth due to change in the overall climatic conditions of earth are common. However, the recent concern over the endangering of the wildlife has been due to overindulgence of man into a reckless (un)economic growth (Venter, Brodeur, Nemiroff, Belland, Dolinsek, & Grant, 2006). Anthropogenic activities have altered the global extinction rate of the species to raise three or four times (Polasky, Doremus, & Rettig, 1997).

This article tries to find reasons as to why is it difficult to conserve wildlife in Canada. The paper is divided thus: the second section presents a background of the problem at hand, the third section presents a brief review of the existing literature; the third section throws some light on the methodology, the fourth section performs data analysis, the fifth section develops regression model for statistical analysis and the sixth section concludes.
