6910 languages

Last week I read one article in the newspaper.

コロ語 is the ne of the 6910 languages.
It is used by a very small tribe in India.
Only 800 people use this minor language.
However, this tribe doesn't have people under 20 years old.
So this langueage may disapper soon.

Reserchers say that
"Half of the 6910 languages will disappear by 2100.

This surprised me very much.
