The idea that 40 to 100 million people were living in North America seems rather ludicrous considering the population of the U.S. was less than 100 million in 1910.
But postulating some outlandish number must somehow satisfy the PC view of the natives being being happy and numerous until the evil white men came.

Bring back the Italian guy pretending to an Indian, he was good for a laugh.

"40 to 100 million"

There are absolutely no societies built on hunting/gathering, as most of the North American Indian tribes were, that can generate enough food to support forty million or more people. North of the Rio Grande the Indian population probably was in the area of two to five million at most. In central America the Aztecs had cities and the populations there were probably a lot larger. But nowhere near forty million. Leftist historians (or hysterians) at work again.
