Summary Response #1

In this article entitled “Polar bear facing extinction due to warming waters of the arctic,” the author states that the number of polar bears has diminished because of global warming. First, the author says that many scholars who study climate and zoology are concerned about decreasing polar bear numbers. Second, the author states polar bears are threatened by rising temperatures. Third, polar bears eat lots of various foods but not penguins. In conclusion, the author points out that polar bears are facing extinction.

It is clear that global warming affects the decreasing polar bear. The author has a valid point. Global warming is destroying the Arctic and polar bears are leaving more and more. Therefore, people need to help polar bear to stay in their place.

First of all, polar bear numbers are decreasing because of global warming. Nowadays, the ice shelves keep melting and sea levels keep rising. This article said scholars of climatology and zoology are warned that reducing polar bears is caused by global warming. So, global warming is a serious problem and we need to know what this problem will be.

Second, rising temperature is contributing to polar bears’ decreasing. According to this article, polar bear only can live the place that is a cold place. However, it is a serious problem that polar bears are moving away from the poles because they can only live and hunting in thick ice. It’s going to cause the extinction of the polar bear. People have to think about polar bears moving because extinct animals can’t be recovered. Therefore, we need to help the polar bears by providing a secure and stable place for them.

Third, the polar bear eats a lot of various foods and animals. The author said that they only don’t eat penguins because they live in Antarctica. So, if Antarctica’s ecosystem is destroyed, maybe polar bears will start to find another kind of food. It could work negatively on Antarctica. They will get many changes; also they’ll appear among the people. Already I’ve seen some case of polar bears appearing among the people. It will increase and before it increases we need to prevent.

In conclusion, we need to find a way to prevent polar bears from moving and decreasing because of global warming. It contributes to rising temperature and moving the polar bear away from the Arctic. We can help them and many people should know about this strange situation. Unless we do, they will become extinct.
