I think the best way to learn is by doing.

I have to say to myself that some birds aren't very close. Their feathers are just too bright. When they fly away, you know it's a sin to lock them up, and you'll be inspired by them. Still, the place you live in is that much more drab and empty that they're gone. I think I really miss my friends.

世界是生者的地方，死者在其中没有位置。

Sustainability isn’t a cost; it’s an investment in our collective future.

忽视环境影响的生产力指标只是会计把戏，而非真正的进步。
