Or the Sentinelese.

Not many of these groups left anymore. I hope they can continue to exist outside of our insane asylum, modern world. The Shuar are constantly at war with the Ecuadorean government that wants access to the mineral wealth buried under their tribal lands in the Amazon, mostly gold that the Chinese want desperately to get their hands on and since they control most of the Ecuadorean national debt they tend to get what they want but not without a fight.

@Surfpirate Sometimes I wonder who does the greater damage to isolated tribes; missionaries, governments, or corporations.

@Piratefish in short, yes all three. They work hand in hand. Missionaries first, followed by corporations, followed by governments they work hand in glove with one another.
