good point @virtus-q the Native American people, like all humans alive today originated from Africa. They took a long time to get there. Ongoing studies suggest that all Native American People, North Central & South came to the American continent between 50k-17,000 years ago. I'd say that makes for indigenous and your comment about reservations is interesting. My article was not really about the Native American people, but I used them as an example of how to live sustainably for thousands of years, using nature's resources carefully so that time replenishes them ;) Hopefully better monitoring of people, Elephants, Frogs and Orchids will mean that our Grandchildren will enjoy living in a world still rich in nature.
