Argument 6

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.



写作:



According to the argument, the author concludes 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 allegedly melting away due to the global warming. To support this conclusion, the author cites the local hunters’ saying and states arctic deer’s life habit. He also establishes correlation between the decline and global warming. However, the argument relies on a number of doubtful assumptions and is therefore unconvincing.



The first place according to the report from local hunter the deer populations are declining. But absent evidence to explain how hunters investigated. It is likely that the hunters cannot hunt the equal number of deer as before so they have the thought that deer populations are declining.And the author fails to rule out the possibility that it is hunter and poaching lead to the decrease of deer number. Even if the hunters' investigate is reasonable and valid, the decrease may be a normal phenomenon result from the natural rule of survival of the fittest. The author fails to account for the number changed for decades. I have reason to suppose that the decrease has happened before and the number has went back. Without more evidence stating the argument cannot convince me.

In the second place, while it is true that the number is declining, this is not true that the reported decline of the deer population coincides with recent global warming trends that have caused the sea ice to melt. The global warming is not an accidental event. It has last for decades or hundred decades. But the decline happened recently. A direct correlation between global warming and the decline does not necessarily prove that the former cause the later. Without more specific evidence the argument can be rejected out of hand. In spite of the global warming has made a great contribution to the decline, it is much possible that the result of global warming such as the decreased food which arctic deer like, the changed element of air and the born of new virus that cause the drop of fecundity.



Finally, the argument describes habits and migration of arctic deer. But lack additional information about the cited studies. If the observation is short of authority, I have good reason to doubt this study. Although this is entirely possible that deer’s habits and migration has changed, the argument provides no evidence to support this assumption.



To sum up, the arguer’s argument mentioned above is not based on valid evidence or sound reasoning, neither of which is dispensable for a conclusive argument. In order to draw a better conclusion, the author should reason more convincingly, cite some evidence that is more persuasive, and take every possible consideration into account.
