Well said Richard.

And well said, gnu.

Random musings:

Primitive living is also a good method to control for over-population. Lots of environmentally sound checks and balances. I don't say that flippantly or sarcastically, simply a statement of fact.

A casual perusal of Native American artifacts over time shows that Native Americans were very quick to take advantage and make use of European technologies and materials.

There is much controversy and mystery about the reasons behind the collapse of the Classic Mayan civilation, but over-population was undoubtedly a factor. At least over-population to the extent that the population density had increased, compliments of advanced agricultural technologies which made it possible, under "normal" climatological conditions for the region and the the time, to feed many more people in a much smaller area. Then along came a severe and extended period of drought.... Mind you, Mayans and Mayan culture did not disappear from the face of the earth, though what is now known as the "Mayan Civilization" did pretty much disappear. I don't think anyone would argue that the Mayan's were not indigenous.

In the end, the laws of nature prevail. Checks and balances in nature can only be avoided for so long....
