It might surprise you to know that there are over 6,000 different languages in the world today; however, many of these languages are close to becoming extinct as the people who speak the languages die before they are documented. Thankfully, there is a new documentary making its way around film festivals called, "The Linguists," that focuses on the importance of language documentation. Following is a plot summary from IMDb:
David and Greg are "The Linguists," who document languages on the verge of extinction. In the rugged landscapes of Siberia, India, and Bolivia, their resolve is tested by institutionalized racism and violent economic unrest.
Here is a link that lists the screenings of the documentary and a link to view the documentary's trailer.
