"The loss of human culture is frightening. Nearly all the threatened languages are spoken by indigenous peoples and, along with the languages, the traditional knowledge of these cultures is being forgotten. The names, uses, and preparation of medicines, the methods of farming, fishing and hunting are disappearing, not to mention the vast array of spiritual and religious beliefs and practices which are as diverse and numerous as the languages themselves."
According to a report by researchers Jonathan Loh at the Zoological Society of London and David Harmon, the steep declines in both languages and nature mirror each other. One in four of the world’s 7,000 languages are now threatened with extinction, and linguistic diversity is declining as fast as biodiversity – about 30% since 1970. (via climateadaptation)
