Very easy read! Provides hope with a needed wakeup call. Should be a class room text for studies of the environment in high school.

Back blurb: As the world's population explodes, cultures and species are wiped out, and we have now reached the halfway point of our supplies of oil, humans the world over are confronting difficult choices about how to create a future which works.
Thom Hartmann proposes that the only lasting solution to the crises we face is to re-learn the lessons our ancient ancestors knew - lessons that allowed them to live sustainably for hundreds of thousands of years - but which we've forgotten.
Hartmann shows how to find this new and yet ancient way of seeing the world and the life on it, allowing us to touch that place where the survival of humanity may be found.
