Lizzie, well meant, but these days, I think there are just people who are all trying to love the planet, etc. i.e., it's not limited to just "indigenous" people. To be sure, there was some good management due to migrations, controlled burning, careful hunting, etc., but those days ended when reservations were established, etc. There are vast differences between them nowadays, too. No generalisations fit. There are wealthy tribes raking in the dough ala the "white man" in casinos, etc. and there are still dirt poor reservations where people live a depressed and poverty stricken life.
