问题 Which of the following statement has nothing to do with the drastically declining number of birds?
According to the author, which is the most feasible way to protect birds?
选项 A、Use fences to protect all the parks in the world.
B、Try to protect wild space and nature.
C、Abandon the economic values that birds can bring.
D、Rely less on agriculture and return farmlands to forests.
答案B
解析 推理判断题。根据"Without stabilizing climate and human numbers, putting fences around all the parks in the world will not be enough to protect threatened species".可以断定选项A不正确。文中提到"If birds disappear, so do the economically valuable services they provide"，但并没有提出要求人们放弃鸟类带来的经济效应。因此C也不正确。虽然文中提到了农业发展同森林减少之间存在一定关系，但选项D中的做法并未提及，而且也不具有可行性，故选B。
