I hadn't actually looked through any of this series of books until this weekend when a friend gave me Hungry Planet. It seems that everyone is familiar with these and I'm glad to finally have a chance to sit down with this book (and I finally got Material World and some others on hold at the library).
And it is a great book. There isn't a lot of commentary, but there doesn't need to be because the pictures speak for themselves. It's so interesting I've even been balancing it on my knee while I'm breastfeeding the baby, and big books are usually banned during breastfeeding.
