The barrier to change is not too little caring; it is too much complexity.
改变世界的阻碍，并非人类的冷漠，而是世界实在太复杂。
To turn caring into action, we need to see a problem, see a solution, and see the impact. But complexity blocks all three steps.
为了将关心转变为行动，我们需要找到问题，发现解决办法的方法，评估后果。但是世界的复杂性使得所有这些步骤都难于做到。
Even with the advent of the Internet and 24-hour news, it is still a complex enterprise to get people to truly see the problems. When an airplane crashes, officials immediately call a press conference. They promise to investigate, determine the cause, and prevent similar crashes in the future.
即使有了互联网和24小时直播的新闻台，让人们真正发现问题所在，仍然十分困难。当一架飞机坠毁了，官员们会立刻召开新闻发布会，他们承诺进行调查、找到原因、防止将来再次发生类似事故。
