Title: Skip the second half
Review: The first half of the book has some interesting historical and archaeological information about Easter Island, Greenland, the Maya, and the pre-columbian American Southwest. If the author had stopped there I would have given it 4 stars. The second half is the author's diatribe about all the terrible things modern societies are doing to the planet yadda yadda yadda. You've heard it all before. His buggabear is deforestation. Legitimate, perhaps, but if I want to read opinion pieces I disagree with, I'll read the NY Times. Still, the first half - except the first chapter on Montana - is a good read.
