The argument is well presented, but not thoroughly well-reasoned. By finding that reports about the declining population
of the Arctic deer coincide with recent global warming trends that have caused the sea ice to melt, the argument concluding
that the decline in arctic deer population is the result of deer being unable to follow their age-old migration patterns across
the frozen sea seems logical.
However, the editor fails to consider that the reports from local hunters that the deer population is declining may not
really reflect the truth. The local hunters may tell us a lie on purpose that the price of their may rise after merchants
hear that the deer is less. The hunters may actually tell us what they have seen, but their finding of declining population of
the deer may not reflect the truth. The deer may transport to some other palces that the hunters don't find, in which situation,
the population may stay the same or even rise.
The reports' coincidence with recent global warming trends may only has a relationship on the level of time. A global
warming trend doesn't mean that the aera where the arctic deer live is warming too. It is entirely possible that although the
aera is colding in the global warming trends. Even the aera is warming too, we still fail to conclude that the decline is the
result of deer being unable to follow their age-old migration patterns across the frozen sea. Maybe the extent of the warming
climate doesn't reach to the level of causing the sea ice in this aera to melt.
The editor fails to consider other possible alternatives to the decline of the deer population. The decline may result
from some diseases that occurs in various reasons, such as the variation of food they eat. The death of the deer in large
scale may be due to the pullution of rain, water resources or air. Moreover, the rising population of the deer's natural
enemy can also make the decline of the deer's population.
Overall, the conclusion that the editor make may be one of the possible causes of the decline of the deer population.
However, because of its short of strong evidence, we still need to consider other possible alternatives that will result in
the declining population.
