Salt Lake City, UT – By the end of the century, 90 percent of the world's languages may be gone. Thousands are extinct already, from Cochimi in Mexico, to Carthaginian in Tunisia. Here in North America, the American Indian languages that remain, like Shoshone, are barely hanging on. Five hundred years ago it was spoken as far north as Yellowstone, all the way down to Death Valley. But intensive efforts are underway to document and revitalize languages like Shoshone. KUER's Jenny Brundin reports on a language apprenticeship program for Shoshone youth.
