The journalist asserts in the editorial that the decline in arctic deer populations result from beer being unable to follow their age-old migration patterns across the frozen sea.To support this assertion, the journalist cites several facts and assumptions that the main cause of the decline roots in global warming trends. However, close scrutiny of these assumptions reveals that none of them lend full evidence to support the conclusion as it stands.

First, the report from local hunters fails to concretely indicate the decline of the deer population. In fact, we cannot conclude that the population of arctic deer has concretely declined merely by one result from local hunters. The deer's habitat is islands in Canada's arctic region, where is in poor living condition especially for human beings, then it is entirely possible that the deer have shift to other island nearby to escape from the hunters, which might render no decline in fact, the report is just misleading information. Thus, the journalist should take a further research in varies of respects to substantiate that the deer population has indeed declined.

Secondly, though these reports coincide with recent global warming, some other factors may also contribute to the decline rather than merely the recent global warming trends.Even if the decline accords with the recent global warming-which is still dubious, the journalist cannot prove the correlation between the two phenomenons. There might be some other factors impacting with the decline. Perhaps, it is certain change of climate, such as cold temperature, that leads the plants on which they feed to disappearance. Without such plants, the deer live in the environment that is scant food, which at last threatens the deer’s survival. Or perhaps, excessive hunting for the deer that damages balance of the deer species serves to the decline. Hence, without ruling out more information from scrupulous researches, the journalist cannot conclude the exact correlation of the decline and the recent global warming.

Finally, even we concede that certain relations exist between the decline and the recent global warming, the journalist cannot justify the reason for ice melted is that the beer being unable to follow their age-old migration patterns across the frozen sea. As the temperature increase the recent global warming, it is entirely possible that submerge of several islands the deer live on serves to bringing the decline of the population. Also, as mentioned in the editorial, their habitat should, at least some of the years, be cold enough for the ice to cover the sea separating the islands, allowing the deer to travel declining. Common sense and experience tells us the extent of the global warming has not been as severe as to melt all the frozen sea around the earth any time of a year, let alone in the arctic region, where the temperature comes out extremely lower than average level. Since the evidence upon which the assumption relies is unpersuasive, the journalist fails to convince me with the assumption.

To sum up, the journalist fails to justify the conclusion being credible. To make the conclusion convincing, the author has to prove the population indeed decline and the correlation of the decline of the global warming.
