A really enjoyable book. To sum it up, agriculture wasn't such a good change, and the things we've done to make it better have done a lot to screw up the environment. This is easy to agree with, except most knowledge came from cities and thinkers with access to libraries. Seriously, though, this is a great overview of food's effects on civilization from the beginning through now. This book sheds light on topics that not a lot of people have considered, and these interesting tidbits make for fascinating reading.
