We know from history that waves of innovation, from the steam engine to the information and communications revolution, have led to dramatic increases in economic growth. We cannot prove that a wave of environmental innovation will have a similar effect, but the studies of the parts make such an outcome highly plausible.
这说明，虽然人们尚未可以确凿证明绿色增长是有效的，但也不意味着我们应当放弃这个理念。我们都从历史上中看到过那些革新的浪潮，从蒸汽引擎到信息与通信革命，都引发了激动人心的经济增长。我们无法证明一股环境革新的浪潮会产生类似的效应，但针对不同部分的研究使得这样一个结果更有说服力。
