Some of the projects about Endangered Languages
Enduring Voices Project  is carried out by National Geographic and Living Tongues Institute for Endangered Languages. The aim of the project is to find out the places where endangered languages are spoken, to prevent their extinction, to document linguistic and cultural materails for the identification of their geographical distribution, to understand how linguistic variation feeds also biological variation and to raise awareness on language deaths. A map displaying endangered languages can be found on the website.
