Two hundred years ago, the Pacahuara tribe was one of the main indigenous groups in Bolivia.
But in a few years their language and culture could vanish forever as the last members of the tribe die out without having passed their knowledge on to a new generation.
The BBC travelled to their village in a remote area of the northeast of the country to talk to the remaining members of the tribe.
