Of the world’s seven thousand languages nearly half will disappear by the end of this century. Their extinction means the end of entire cultures, traditions, and histories.

K. Davis Harrison and Gregory Anderson are on a mission to save these dying languages. They’re linguists, but not the kind who spend their lives in libraries and classrooms.

They travel the world — from the Bolivian Andes to the steppes of Siberia — searching for the last speakers of native tongues. Think of them as action-adventure linguists with a cause.

This hour, On Point: the race to save vanishing languages.
