有人说，这是最好的时代，也是最糟的时代。从电话、电脑到飞机、高铁，我们享受着前所未有的便利。其代价，却是对资源的过度消耗，对自然的大肆破坏。当这些消耗和破坏已不可逆转时，人们才发现，原来青山绿水才是可持续发展的资本，也是滋养身心的源泉。
Some say this is the best of times, and the worst of times. From telephones and computers to airplanes and high-speed trains, we enjoy conveniences never before imagined. Yet the price we pay is the overuse of resources and the relentless destruction of nature. Only when the damage becomes irreversible do we awaken to the truth: that green mountains and clear waters are our foundation of sustainability, and the source that nourishes both body and mind.
