According to recent statements by scientists, the social networking sites like Facebook, YouTube and even messaging is the salvation of many languages ​​in danger of "extinction" worldwide.
In about 7,000 languages ​​are in use on Earth today, about half are expected to be "extinct" in the last century. This situation is blamed by the globalization process, and some elements of the "modern world", especially digital technology, also hastened this process.

 For example, the North American tribes often use social media to connect young people together.
Tuvan, a nomadic tribe in Siberia and Mongolia, there is even an iPhone application to teach the pronunciation of the word for new students.
"The ethnic minorities tend to use social media, YouTube, text messaging and other technologies to expand their voice and expand their presence more , "said K David Harrison, a linguistics professor at Swarthmore College cum National Geographic Fellow said.
Margaret Noori is an expert in the study of Native Americans at the University of Michigan and a spokesman Anishinaabemowin associations, associations of language more than 200 sovereign indigenous "nations" in Canada and the U.S.. These communities were rated as the "loyal fans" of Facebook.
"We use technology with a single purpose, which is trying to connect people," said Professor Noori. "At the same time to preserve the language."
Dr. Harrison said that not all languages ​​can exist in many languages ​​of the ethnic minorities will be lost forever. However, fortunately, the new digital tools have become the "savior" of many kinds of language seems to be facing extinction only a few years ago.
He has stated on the forum BBC News: "Everything that people know about the planet, about plants, animals, lifestyle, the Arctic ice cap, the different ecosystems that people survived - all of this knowledge are encoded in the culture and language of the people, whereas only a small part of it is encoded in the scientific literature. Therefore, if we we care about the sustainability and survival on the planet, we all have benefited from the foundation of modern technology. ".
