-Something like 10 percent of population of the planet live in the basin, the wide area around the Yangtze River. That is how important this water, this river, is. Just come over here, look what we as a species are capable of. This is, it's display here, I think, like nowhere else I've seen on planet earth, really. They have blocked, contained, controlled the Yangtze. And now look over here. It's like looking at a side of a mountain. You're proud of it?-Yes, why not? I'm proud of it.
