How Clinch Weather to Become Warm Problem
The amount of greenhouse gases we’ve already pumped into the atmosphere has irreversibly bound us to a certain amount of warming over the next several decades. That means climate change isn’t a problem for tomorrow—the effects are happening now. Already raining patterns seem to be changing, making some drier areas even drier, and rainy regions even wetter. As warmer temperatures creep northward, so do insects and other pests that are adapted to the heat. The population of the tiny mountain pine beetle, which infests pine trees in the Rocky Mountain region, used to be controlled by freezing winters. But as temperatures have warmed over the past decade, the mountain pine beetle’s territory has spread, destroying millions of acres of Canadian pines.
The pine beetle infestation represents the unique challenges that warming will pose for land conservation managers on the front lines of the battle against it. Generations of American conservationists have fought to preserve wildlife and to keep nature pure in the face of a growing population and pollution.
But global warming threatens to change all that, by altering the very foundation on which the conservation movement was built. What good is a wildlife reserve if the protected animals can’t live there, because climate change pushes them out? What difference does it make to defend trees from logging, if global warming will allow a new pest to ruin the whole forests?
The answer is to adapt the way we practice wildlife and land conservation to climate change. There’s a term for this— adaptive management. We need to begin making moves today to adapt to changes that warming will bring decades hence. "Climate change will affect anything, you name it," said Lara Hansen of EcoAdapt. "We need to change the way we allocate resources and protect livelihoods."
That means that the way we’ve been carrying out conservation—picking the right land spaces and playing goalie— won’t work anymore, as climate change keeps moving the target. Conservationists will have to work even harder, trying to minimize non climate-related threats to land and species even as the human population grows by billions. Regardless of what we do, the changes will be coming fast and the future would bring increased drought, heat waves, rainstorms, extinctions and more. We need to begin cutting our carbon immediately, but we need to adapt now as well The world is changing because of us; to save what’s left, we’ll have to change too.
From the passage we can learn that pine beetle______.
选项
A、mainly lives in America
B、can be killed by coldness
C、multiplies faster if warmer
D、has no natural enemies
答案
B
解析
推理判断题。根据题干关键词pine beetle定位到原文首段第五句:The population ofthe tiny mountain pine beetle,which infests pine trees in the Rocky Mountain region,used tobe controlled by freezing winters.可知,以前冬天的寒冷就会杀死一部分寄生于落基山脉松树上的山松甲虫,从而控制它们的数量。由此可知,寒冷会冻死一部分山松甲虫,故选[B]项。
