Several factors may me directly or indirectly responsible for the declining numbers of the Canada's arctic region deer, and examining various evidences is necessary to find the reason for their reducing population. Increase in arctic area population leading to increased hunting may be a factor for the reducing arctic deer numbers. Also due to melting of sea ice may have affected the plants in the region. An increased number of other predators may also be the reason for reducing arctic deers, thus the purported decline may not be because of difficulty following the migration patterns. Firstly, the deers search for food in areas warm enough to sustain plants, but cold enough for ice to cover the sea, for their migration. The climatic changes because of global warming may have affected the plants and other vegetation in the Canadian Arctic. The plants which were food for the deers may have been destroyed by the unfavorable conditions, resulting from the global warming. Along with it, due to decreasing…show more content…
Global warming is causing the arctic sea ice to melt. But still during the winters, the islands might not be inaccessible as all the ice from the arctic has not yet melted. Less ice on the sea might have caused the deers to be hunted by sea predators. Also the ways to the islands may be unsafe due to inconsistency in ice thickness. The migration to others islands might still be possible but the journey has become more dangerous than old times, killing most of the deers during the journey. Thus, climatic change having reduced the food supply for deers; increased hunting might be the factors for reducing deer numbers and unsafe migrations may be possible reasons for declining deer numbers. Concluding, considering the mentioned points it may be possible that the purported decline of deer populations may not be because of their difficulty following age old migration
