Dr Harrison says not all languages can survive, and many inevitably will be lost as remaining speakers die off. But he says the new digital tools do offer a way back from the brink for a lot of languages that seemed doomed just a few years ago.
He told BBC News: "Everything that people know about the planet, about plants, animals, about how to live sustainably, the polar ice caps, the different ecosystems that humans have survived in - all this knowledge is encoded in human cultures and languages, whereas only a tiny fraction of it is encoded in the scientific literature.
"If we care about sustainability and survival on the planet, we all benefit from having this knowledge base persevered."
