There are about 6，500 languages spoken throughout the world，but about half of them are in danger of disappearing.

One of the primary causes driving language loss is that support for language communities drastically varies.While some languages are recognized by governments and taught in schools，the majority go unrecognized，unsupported，and untaught，leaving communities ill-equipped to pass their languages on to future generations.Tsakonian，a“dialect(方言)”in Greece，has declined to the point that only 100 speakers remain.

When a language disappears，many other things can go away as well.For example，parts of a community’s culture，knowledge and identity can also be lost.

One organization seeking to save world languages is Wikitongues，which was founded as a school project by Daniel Bogre Udell in 2012，when he began recording short oral histories in New York to explore the city’s rich cultural diversity with the simple idea:tell me about yourself or your home in your native language.When he posted the videos online，the channel quickly got wide attention.

There are currently over 400 languages and dialects represented on Wikitongues’channel and more than 1，500 people from 70 different countries have added videos to it.But that’s far from enough.The organization seeks to serve as an Internet resource to keep as many languages as possible alive.Udell believes they can make it happen.“There are many examples of languages that disappeared but later returned to use.Hebrew went extinct in the 4th century BC，and was revived(恢复)in the 1800s.Now once again，it's the mother tongue of half of the world’s Jewish population，”said Udell.
