Shepard Krech debunks the myth of the "Ecological Indian" who lived in harmony with nature. Krech argues that Native Americans contributed to megafaunal extinctions through overhunting. He cites evidence that overhunting led to the extinction of 13 bird species. Krech also notes that Native Americans used fire extensively to destroy animal habitats and facilitate hunting, and that the profitable deerskin trade led to the mass extermination of white-tailed deer. Despite images of untouched nature, Krech concludes that the landscape was culturally and anthropogenically shaped by Native American use of fire.
