International Mother Language Day

Posted: Updated:

KENNEWICK, Wash.-- International Mother Language Day was celebrated in Richland on Sunday.

People gathered at the Battelle Auditorium to celebrate 15 different languages and teach each other about their cultures.

UNESCO created the day in 1999 to bring awareness to dying languages and promote educating others about them so they survive.

"The importance is the diversity of culture is dying out. There are thousands of languages all over the world which no longer exist," said Sandip Dasverma, event organizer.

Studies estimate that half of the languages spoken in the world will die off by the end of this century.
