So this course is really designed to get you to think about

因此这门课还会让大家更加深入思考
what's worth worrying about in a deeper way

真正值得关注的问题
as a way to encourage you to think about your own behavior

以此让你们思考自己的行为
but also how you might encourage others

同时你们如何使其他人
to behave in a more responsible way.

在环境问题上自觉承担责任
This is not a course in how to be an environmentalist,

这门课不会教你如何成为一个环境学家
it's a course in how you might think about

这门课会教你
defining problems and solving problems

认识问题和解决问题
to really help us think about the world that we're creating,

帮助大家了解这个正在被我们创造的世界
a world with many billion more people in it,

因为在这个世界上仅有很少的资源
given our scarce resources.

但却有成万上亿的人在这里生活
