Nearly Extinct

I was reading somewhere that Brazil had the largest group of uncontacted tribes of anywhere in the world,but what made me want to learn more was they used the number 77 for the amount of tribes and I wondered if they were uncontacted how they  could possibly know there were 77 tribes? The answer is they don't know,that is just an educated guess. The people of these tribes are in constant danger from loggers and ranchers who want the land they live on,and of course any contact with the outside world is a chance that the tribe will be wiped out from introduced disease like the common cold or flu,much like what happened with our own Native Americans. They will only survive if their land is protected,so they  can continue to live in peace,free
from the fear of extermination and disastrous contact.
