The Effects of Global Warming on Polar Bears Research Paper

The Effects of Global Warming on Polar Bears - Research Paper good exampleDespite ongoing activism this decrease in numbers still continues up to the present day. Indeed, it is a frightening possibility that soon, polar bears will be estimable parts of history and will become some other name on the list of extinct animals. The decline in Polar Bear population is payable to firearmy harsh realities in todays world. With not only traditional adversaries in the wild to contend with, the additional factors of climate and the encroachment of man begin to play a big factor in the Polar Bear saga. Chief among the causes of the polar bears steep mortality assess is hunting by humans (Schliebe et al. 34). Another cruel by-product of the influence of man is the exposure of the bears to Persistent Organic Pollutants (POP), highly toxic chemicals. The high levels of aggregation of POP compounds cause impacts to the polar bears nervous system, reproduction, and even their immunity (IUCN Re d List 1). This man made problem has begun to substantially jeopardize the health and well-being of the animals. Taken together, these problems alone would be hard for any species to face. However, overshadowing other issues is the advancing argument that the biggest threat to the existence of polar bears is the phenomenon of global warming. The invariable and intensifying climate changes have already made impacts on the polar bears sea ice habitat. With entire shelves falling prey to the cracking and once right on ice floes reduced to a mere shade of their former selves the ability to deny that the polar caps are warming is nearly impossible to dispute. As a result, their ice covered habitat has been disrupted in a complete and fundamental manner. With even the very fabric of their existence shifting under their feet, their instincts ascertain little recourse. This deeply affects their access to prey and den areas. It is a very strong position to state that the effects of glob al warming are seen to be critical to the polar bears extinction (IUCN Red List 1). This research will explore the possible effects of global warming on polar bears. The issue is in need of special attention because the likelihood of polar bears extinction is a very important environmental concern. With the continuous climate changes, and the human population stuck in perpetual deadlock, affecting the habitat of polar bears, it is very likely that our environment will lose another biological component. This research paper will assess how the impacts of global warming are contributing to the likelihood of polar bears extinction. In straddle to gain a full understanding of the effects of global warming on polar bears, this paper will focus on three areas of literature. First, the drive looks at the area that attempts to comprehend and illustrate that the polar bears are the bears of the sea. Second, the paper will examine the literature that discusses the effects of global warming o n the ground in general. Third, the research will delve into the effects of global warming on polar bears specifically. By taking the time to examine all of these canonic facets, the picture of the plight of the Polar Bear begins to come into focus. First, we start by learning about the polar bear. Long regarded as the largest terrestrial carnivore in the unit of measurement world (World Life Fund for Natures Status Report), the bear has few natural enemies. According to Norris et al, its scientific name is Ursus maritmus (8) was
