It's the children's version of Fast Food Nation. It was a very quick read, interesting, and I didn't feel like it was dumbed down for teenagers. I especially enjoyed the social justice part- a different twist than the normal "we should all be vegetarians" that I expect from these books. They discuss how teenagers are exploited by fast food companies and how they break unions. There was also the normal stuff about the environment and animal suffering. I care about all of that, but obviously not enough to really change my behavior. I also feel that I've heard all of it before, even though I'm re-amazed by it every time.
I do want to eat slightly better than I have been.
