The title of this non-fiction book explains what this book is about. The author is emeritus professor of biological science at Southeastern Oklahoma State University and of Cherokee heritage. He cites all the historical findings and current research regarding how natives used fire to control forests and grasslands, the numerous large native cities found both in US and Latin America using lidar technology, and how the colonists were totally mistaken when they thought they had found a land that lacked the influence of humans regarding forestry, farming, orchard keeping, etc.

He notes that the way the indigenous people in the US farmed and maintained orchards was not like those of the Europeans so they thought no one was doing anything and they were incorrect. He also goes into a lot of the history about how European diseases especially brought about the demise (genocide) of millions of native peoples even often those who had not themselves seen Europeans. Many European diseases spread from domesticated animals to humans (he provides a long list) and natives had no immunity. He cites of only one Western Hemisphere disease (syphilis) that went from the Americas to Europe. He claims that there were so few native diseases in this hemisphere because there were no large animals to domesticate.

The way Native Americans farmed, maintained forests, established orchards, etc. was so different from the European way that Europeans thought no one was doing anything productive with the land. To the contrary, they were affecting the land greatly but in ways that were more sustainable. Currently, he notes in the US forest management people have begun to recognize Native American forestry expertise and use it in many places.
