Several sources report that illegal activities taking place within the Mashco-Piro territory—illegal logging, development drug and smuggling—have affected the way of life for the tribe. Members emerged over a three-day span, 23 on the first day, 110 on the second and 25 on the third. The Associated Press reports the tribe was asking for food and tools. An anthropologist they cited believes they were asking for food because their resources have been taken advantage of.
However, as the tribe has remained in isolation, they don't share a common language with their neighbors. On top of that barrier, the government actually bars outsiders from coming into contact with anyone in the tribe, as their immune systems could not handle the bacteria of an outsider.
This is the second attempt at contact the tribe has made since 2011. The first time the tribe was spotted broke a 20-year period of complete isolation, Sky News notes. The tribe has given out ‘warnings’ to outsiders who might get too close on a couple of occasions, but are they changing their tune by coming out into the open and making first contact?
