对付一个不自由的世界，唯一的方法就是变得如此绝对自由，以至于你的存在本身就是一种反叛。

我尝试以开放的心态和学习的意愿来接近每个角色。

可持续性不仅仅是一种趋势；它是对后代的责任。

The world is a place of infinite connections, and we are all part of that web.

The world has the technology - either available or well advanced in the research pipeline - to feed on a sustainable basis a population of 10 billion people.

The pace of change will never be slower than it is today.

如果不符合现实，最优雅的理论也是无用的。
