Great article but this line at the end is a bit weird:

"These villagers themselves have yet to reap many of the benefits of modern civilization, including electricity, clean water, or employment opportunities"

Employment opportunities? Really? Isn't that kind of missing the whole point?

There are still many "uncontacted" tribes in the world (http://en.wikipedia.org/wiki/Uncontacted_peoples). I find the Sentinelese people most fascinating of them all. They violently fight anyone getting near their island. They are probably lucky to be on a place where not many resources can be extracted, so no body bothers them.

Thank you for this link. I wasn't aware that there are still several "uncontacted" tribes, especially in South America. Fascinating.
