When Languages Die by David L. Harrison

The Extinction of the World's Languages and the Erosion of Human Knowledge

A concise exploration of the global extinction of small languages, showing how their loss erodes unique human knowledge about ecology, medicine, navigation, timekeeping, and culture. Drawing on firsthand fieldwork in remote communities, it reveals how vocabularies encode specialized expertise, examines social and political forces that drive language shift, and argues for urgent documentation and community-led revitalization, including the use of digital tools, to safeguard linguistic and cultural diversity.
