I found this short [22 min] documentary on google video: Yu Koyo Peya, exploring briefly the sad future our society may face as a consequence of our unsustainable practices in a world of 6.5 billion people. The image and sound quality are a bit poor, but that is probably to allow for people with slow net connections. It ends on an interesting, maybe bittersweet note. It covers so many things that I'd like to comment on, but on reflection I just can't say anything at all. Peter.
