Preservation efforts for Mexican indigenous language

Triqui de la baja (trc) is an indigenous language of the Copala region of Oaxaca, in southern Mexico. The language is considered at risk of extinction. This article reports about the efforts for preserving it, and about its value as a precious source of traditional ecological knowledge, as shown by Gloria Moreno. Moreno's knowledge of herbal medicine may get lost as the language struggles to survive and be transmitted to younger generations.
