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.

The argument asserts that the decrease in arctic deer population, which is reported by local hunters, is concomitant with global warming and concludes that the former is the direct result of the latter. However, drawing such conclusion should be bolstered with objective evidences and realistic information, which unfortunately is not included.

The passage claims that the number of arctic deer living in Canada's arctic region is decreasing based on some reports from hunters. Since the hunters are not authorized source for reliable information about deer population, the claim is biased and may be just a subjective feeling of a few numbers of hunters. Knowing the accurate statistics and numbers of arctic deer in recent years, make the comparison between present and past size of deer's population possible. It helps to clarify whether the reduction is real or not.

Moreover, the hunters are local observers, but the global warming is a universal problem. To verify the plausibility of the mentioned claim, the writer should include statistics about other arctic denizens whether inside the Canada boundary or outside it. If there is a consistent reduction in other arctic species or some species of arctic area outside Canada the claim will be supported as being the result of a global affecting factor.

Finally, it is rather important that the passage contains the exact regions where the hunters believe there is a reduction in deer's number. It needs to be verified whether the warming and interruptions in deer migration passages are the cause for presumed problem or there is other environmental problems. For example, if the underlying cause is an outcome of unrestricted hunting of deer, the global warming should not be blamed.

To sum it up, when a pair of concomitant conditions coexist it does not necessarily mean that they have a cause and effect relationship with each other. In the above case, an accurate data about exact percent of reduction among deer's herds, the regions encountering the problem, and other coexisting factors should be included to help readers to verify the premise of the passage and draw a logical conclusion.
