Ive been reading up on unconacted peoples lately as I find it interesting that they can still exist in today's world. There are many more tribes than I wouldve thought according to Wikipedia.
http://en.wikipedia.org/wiki/Uncontacted_peoples
Uncontacted peoples, also referred to as isolated peoples or lost tribes, are communities who live, or have lived, either by choice (peoples living in voluntary isolation) or by circumstance, without significant contact with globalized civilization. Few peoples have remained totally uncontacted by global civilization. Indigenous rights activists call for such groups to be left alone, stating that it will interfere with their right to self-determination. Most uncontacted communities are located in densely forested areas in South America, New Guinea and India. Knowledge of the existence of these groups comes mostly from infrequent and sometimes violent encounters with neighboring tribes, and from aerial footage. Isolated tribes may lack immunity to common diseases, which can kill a large percentage of their people after contact.
I wonder how in thousands of years, the first world has progressed to make nuclear power, traveled to space, invented transportation, the internet, computers, etc..... Yet these peoples havent even invented clothing yet. How can they still not have figured out the most basic of inventions after thousands of years. When a helicopter flies over them to photograph them or research them, they act like its a giant loud bird. Are they really that ignorant of the world?
Also why dont the countries that they live in make them adhere to their laws? Many of these tribes KILL anyone who comes anywhere close to them and yet they are never arrested for murder.
