This is an outstanding book. The topic is timely, a red alert situation for the whole world, a wake-up call from a distinctly native framework. The clarity of the writing is fantastic. It is easily accessible to anyone and it is a clear statement of indigenous thought and a call to action to move toward practices which native people employed to crate and maintain a sustainable world. Great critique of current practices in society. It challenges our apathy in the face of potential world destruction. It is a great book for a course for undergraduates in many fields, but anyone can read and enjoy it.
