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 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 the 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.

The claim that ” the arctic deer population is declining because of global warming and in turn their inability to follow their age-old migration patterns across the frozen sea” has been made on the basis of reports from local hunters and recent global warming trends. On a casual reading the argument seems convincing but the closer scrutiny brings out certain loopholes in the argument. So it seems to be flawed in many places and therefore is non- convincing.
The conclusion has been drawn on the basis of evidence provided by the local hunters. So the conclusion on this basis has been reached in haste as the hunters themselves are responsible for the declining population of arctic deer. There have been no proper evidences, no strong facts or figures been provided which would convince the readers that the claim is right. Proper techniques and methodologies should be delineated for drawing the conclusion.
Furthermore, it cannot be stated that the population is dwindling because of global warming because with global warming the temperatures would rise and the area would become warm enough to sustain vegetation on which the deer feed. So they don’t need to migrate from one place to another in search of food. So this factor further reduces the strength of the argument and making it flimsy.
Also the reports have been compared with recent global warming trends as stated in the argument without any specification of the region of study. So there have been errors in the test method employed. Application of results of larger domain to a limited area is fallacious. So proper test method with due facts, sample quality and quantity should have been specified which would make the conclusion valid.
In the nutshell, it can be stated that the relation between the deer population and global warming is unsubstantiated. The decline in the deer population may be because of the local hunters, and the global warming will in-fact help the deer population as it would lead to less migrations in search of food. Had the above mentioned facts been provided, the argument would have been plausible.
