可持续性不是一种趋势，而是我们共同的责任。

One of the strongest motives that lead men to art and science， is escape from everyday life with its painful crudity and hopeless dreariness， such men make this cosmos and its construction in the pivot of their emotional life， in ordered to find the peace and the security， which they cannot find in the narrow whirlpool of personal experience.

可持续性不仅仅是一个流行词；它是负责任的采矿的基础。
