Please Explain: Endangered Languages

More than half of the world's nearly 7,000 languages are at risk of dying out in the next century. On this week's Please Explain, we take a look at what causes languages to disappear and the efforts to document and revive endangered languages around the world. Gregory Anderson, Director of the Living Tongues Institute for Endangered Languages, and Anthony Woodbury, Professor of Linguistics at the University of Texas, join us.
