I highly recommend these series of videos. Not just as an anthropologist and a teacher interested in language but as a human being who understands the importance of preserving cultural/ethnic diversity, our cultural genome.
I presently live in Guatemala and this episode makes a great point – our educational systems worldwide are complicit by ignoring and killing/strangling the languages of thousands of peoples in the world. Here in Guatemala, there is not a Mayan language high school or university. Why? They are the majority of people here but we are wiping their world from the sky….
Same in many parts of the world. We need to think harder of our role in this, us language teachers. Also recommend viewing Wade Davis’ passionate TED Talk / speech on this topic, a must. Also see the PBS series “Language Matters“.
