The following are endangered species EXCEPT
Many kinds of animals are endangered by human beings. The United States government list of endangered species includes tigers, grizzly bears, some kinds of whales, and over three dozen species of butterflies. What has led to the scarcity of these animals, which may become extinct without vital protections?
One important factor is that many animals have been widely hunted and killed for food or for their beautiful skills. Besides, some predators are threatened by ranchers to protect their sheep and chicken, such as eagles or wolves. Moreover, some species, like polar bears, are endangered because humans are successfully competing with them for the use of environmental space.
With various animals being killed for food, for decoration, and for the protection of domesticated animals, or dying because of unfortunate contact with human environments, it is not surprising that some are becoming scarce, that the number of species on the endangered list is growing every year. Furthermore, it is important to understand that individual species are not the only factors involved in this dilemma. Endangerment is a broad issue, which involves the habitats and environments where species live and interact with one another. Man is discovering that his world includes the other animals in it, and one can only hope this discovery is not coming too slowly or too late.
选项
A、Contact with human environments.
B、Species competition for food.
C、Protection of domestic animals.
D、Application in decoration.
答案
B
解析
细节题。物种濒临灭绝的原因有很多,比如被人类杀掉作为了食物,做成了装饰品,或成了人类保护家养动物免受侵害的牺牲品。还有一些因为不幸接触了人类居住的环境而即将灭绝。A、C、D项都包含在其中,而B项(物种之间为了食物而斗争)并不是野生动物灭绝的主要原因,而是人类为了食物而杀害它们,才使得它们濒临灭绝,即选B项。
