“The extinction of a language results in the irrecoverable loss of unique cultural knowledge embodied in it for centuries, including historical, spiritual and ecological knowledge that may be essential for the survival of not only its speakers, but also countless others….The most important thing that can be done to keep a language from disappearing is to create favorable conditions for its speakers to speak the language and teach it to their children…. record as much of the language as possible so that it does not disappear without a trace. “ UNESCO
