Arg 6 decline of deer caused by global warming

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.

G1: 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.

G2: Unfortunately, according to reports from local hunters, the deer populations are declining.

G3: Since these reports coincide with recent global warming trends that have caused the sea ice to melt,

C1: 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.

A1 (G2, C1): The reports from local hunters are reliable.

A2 (G3, C1): The global trend is consistent with the local reality.

A3 (G3, C1): Other factors did not affect the livelihood of deers.

P1: more evidence about the accuracy of the hunters reports

- whether the hunters had scared away the deer with their guns

- whether the hunters had visited the area in a particular point in time when the deer were less active

- how many hunters had reported the deer population; the number was small- less reliable

P2: more evidence about the sea ice in arctic region

- whether the sea ice in arctic region had melted (global warming trend does not mean local warming)

- whether more food was available near the habitat due to the climate change (then no need to travel)

P3: evidence that may provide other explanations for the decline of deer population

- other factors that may threaten the deer population- pollution and overhunting
