Day 6 Arctic deer live on islands in Canada's arctic regions

Arctic deer live on islands in Canada's arctic regions. They search for food by moving over ice from island to island during the course of the year. Their habitat is limited to areas warm enough to sustain the plants on which they feed and cold enough, at least some of the year, for the ice to cover the sea separating the islands, allowing the deer to travel over it. Unfortunately, according to reports from local hunters, the deer populations are declining. Since these reports coincide with recent global warming trends that have caused the sea ice to melt, we can conclude that the purported decline in deer populations is the result of the deer's being unable to follow their age-old migration patterns across the frozen sea.

Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.

五问:

(1)“we can conclude that the purported decline in deer populations is the result of the deer's being unable to follow their age-old migration patterns across the frozen sea”是结论,其余部分是事实,值得反驳吗?

(2)来自当地猎人的报告一定是准确的吗?猎人这个职业是否可能导致他们给出有倾向性的报告?猎人这个职业的活动范围是否会使他们给出有偏差的报告?猎人的调查结果足够客观吗?

(3)两件事情同时发生就一定有因果关系吗?鹿的数量减少一定是因为全球变暖吗?其他原因,比如天敌数量增加,也会导致鹿的数量减少。请回顾一下,我们对因果关系的判定,需要遵循哪些条件?

(4)文章中是否给出了迁徙模式与鹿的数量之间的直接关系?无法迁徙就会导致鹿因缺少食物而数量减少吗?全球变暖也有可能使岛上的植被增加,满足鹿的食物需求。

(5)全球变暖已经达到使冰全部融化以至于鹿无法迁徙的程度吗?有证据证明当地气温升高吗?
