第 Q5qhe3RgnFxnm1t2OI5q 題
Why does the author describe the current threat as an "escalator to extinction"?
- A Because species are moving downwards to the valleys where human activity is highest.
- B Because the speed of evolution is increasing too rapidly for the ecosystem to handle.
- C Because the cloud forests are disappearing due to lack of rainfall in the valleys.
- D Because species moving upward to escape heat eventually run out of physical space at the summit.
思路引導 VIP
作者使用此比喻是因為物種為了留在合適的溫度範圍內而不斷往高處遷移，但最終會遇到山頂的物理極限，無處可去。這是一個幾何上的限制（geometric limit）。
