University of Michigan professor Carmel O'Shannessy has discovered a language born just a few decades ago. "Light Warlpiri" is spoken in the aboriginal community of Lajamanu in the Northern Territory of Australia.
The film "Language Matters" asks what we lose when languages die and how we can save them. It was filmed around the world: on a remote island off the coast of Australia, where 400 Aboriginal people speak 10 different languages, all at risk; in Wales, where Welsh, once in danger, is today making a comeback; and in Hawaii, where a group of Hawaiian activists is fighting to save the native tongue.
