NEW YORK – We have always lived on a changing planet, but many of today’s variations in climatic and ecological states are taking place exceptionally fast, and are directly attributable to our behavior. Slowing the rate of alteration is the only rational course of action, given the potential outcomes.
纽约——我们生活的星球一向不断变化，但今天与人类行为息息相关的许多气候及生态变化速度尤其可观。考虑到由此产生的后果，唯一合理的对策是确保变化速度逐渐减缓。但我们还需要仔细斟酌对策，不然就可能冒着重复短视行为的风险。出人意料的是，在宇宙其他地方搜寻生命的努力或许能让我们从全新的重要视角审视我们的星球。
