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的世界，大陆板块，地球的气候，以及侵蚀，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.

士说，这一理论的问题在于，有些山峰够逃脱冰川的侵蚀作用，然后变得非常陡峭，以至于冰川再不粘在它们的两侧。
