@AC (benefits of moderm society)
For us to take these people out of that environment and put them into a 'modern society' would kill them outright (or may as well do so). Its taken 'modern man' well over 1000 years to gain this much technology and assimilate it in to everyday life. You can't just drop that on these people overnight. The governments of these countries need to step up and protect them.
As the other AC said, they'll be freaked out just by an airplane. I can't imagine how much people in regular clothing, no coloration of their skin (ie. body makeup like them) and guns showing up to take them away would freak them out.
