Researchers estimate that there are more than 100 uncontacted peoples remaining in the world, most of them located in Brazil. The word "uncontacted" can be slightly misleading, however: most of these tribes have indeed encountered outsiders, whether they were missionaries, miners, explorers, or even pilots in planes or helicopters. The debate over whether we should reach out to these peoples is a complex one. Countries have put laws and reserves in place to prevent trespassing onto their lands, but loggers and oil workers are often exempt from these restrictions. One big concern is disease, as the members of these tribes often don't have immunity to certain dangerous illnesses.
The world is uber connected today. It seems like it's just as easy to see your neighbor as it is to see you friend who lives half-way around the world. Facetime, Facebook, Skype — there's no shortage of ways to stay in contact. So it's easy to forget that there are still plenty of tribes of the world that are "uncontacted," and many avoid interactions with civilization because they've been the victims of violence in the past.
