"You probably know that many of the world's plants and animals are in danger of extinction, but did you know that many human languages are in danger of becoming extinct, too? Globalization has helped to make the world a smaller place. But it has also contributed to the loss of many languages around the world. Every two weeks another language disappears forever! Once a language is lost, humanity loses a part of our rich heritage. Helping to preserve endangered languages is important to keep traditions alive."
