We live in a changing world where the continental plates, Earth's climate, and the planet's erosive power might one day conspire to cut Mount Everest down to size.

我们处在一个不断变化世界，大陆板块，气候，以及侵蚀能力，也许会在某一刻共同将峰削低。

The problem with that theory, says Dr Rowan, is that there are some peaks that manage to escape the erosive effect of glaciers, and then grow so steeply that glaciers can no longer stick to their sides.

罗文博士说，这一理论在于，有些山峰能够逃脱冰川侵蚀作用，然后变得非常陡峭，以至于冰川再也不能粘在它们两侧。
