Regarding the "past" and "current" times it is also sobering to read about the U.S. Government, land speculators, ranchers, towns, etc., history of greed for land and power that decimated the Native American tribes as the United States was being developed from the time of the first European settlements and also via the concept of "Manifest Destiny" and Western expansion and interventionism in the 19th century.
I try to imagine what America and our world would be like if the Native American cultures and attitudes about land and wildlife, had been recognized as equal to the early European "invaders." Personally, I believe future generations will condemn this embarrassing history.
I found an "Indian Country Today Media Network site with this animated map that illustrates the amount of land still recognized as being "Indian Lands" in 1784 and how that land was lost progressively through the 1800's to the present time. It should be noted that the original cultures of the Native Americans today has been almost totally destroyed even if tribes still have rights to small reservation lands. In partnership with Indians, we might have learned valuable lessons about how to treat the land, wildlife, plants and our fellow humans.
