In the editorial the editor suggests that according to reports from hunters in Canada's arctic region, the population of local Arctic deer is declining. And the editor attributes it to the recent global warming trends that have caused the sea ice to melt, thus there is no ice for deer to move over from island to island during the course of a year, without enough food they are inevitably dead and then the population is declining. However, I found the editorial not well reasoned and I cannot accept the view as it stands.

First of all, I wonder wether the reports from local hunters are representative. Considering that people living there contains not only hunters but also many others like deer keepers, it's out of question that hunter is not the exclusive perfession which has contacts with deer. Thus there may be many Arctic deer in Canada's arctic region that they are not the targets of hunters and hunters' reports cannot represent the whole deer in the area. Even if I concede that the reports represent the whole deer, the editor overlooks the facts of hunters themselves such as recently many young hunters go to hunt for Arctic deer and they cannot find many  without wealth of experience. In consequence they claim that the population of the deer is declining lately. Without rulling out these possibilitis the editor cannot convince me that the reports from local hunters are representative.

Secondly, in this editorial the deer is considered to be only living in the place where is adequate warm and cold by turns or they would be lack of food. Undeniably that with appropriate temperature, it's very helpfull for deer,especially Arctic deer in the area, to live. But the melting of ice there doesn't mean no food the feed the deer. It's entirely possible that though they cannot move over ice to another place, they have enough lichen or moss to eat and live on through the whole year. In this way they don't have move from one place to another always. Or there are some other alternatives that maybe some local residents have kept and feed them cosmically, then they would impossibly have nothing to eat. Therefore with the mere information given by the editor, it cannot exclude these potential cases which can attack the view fatally.

At last, even if the melting of ice leads deer to death, it's not wise to deduce the decending of deer in the area. There is no certain linking between these two things. We can learn from the fact of dianosours, that when the most kinds of dianosour died in the dark era, some small kinds dodged into the cave and in order to adapt to the situation they evolved to current birds gradually. The same evolvement with Arctic deer can also take place, notwithstanding some Arctic deer may die owing to the warming trend of the world, the others would evolve to a new spiece of Arctic deer which have powerfull fecundity and they are seasoned to most possible situation in Arctic area, not to mention on the island of Canada's arctic region. Ipso facto the death of the majority of deer may result in the larger population.

In sum, the editorial is not well supported. To convince me of the original conclusion the editor must provide more evidence to exclude all the possibilities above and ensure me that there would be no more likely situation either. Otherwise the link duduce is unconvincing.
