Thomas Headland in the article “Revisionism in Ecological Anthropology” outlines some contradictory information about whether tribal societies are natural conservationists. This may be true in some small-scale tribes, but some such as the Bahinemo, living in the mountains south of Ambunti in Papua New Guinea, usually did not act or speak of natural conservationism. This tribe had no experience with the outside world, and they only made decisions concerning the immediate future.
