By 2115 about 90% of the languages in the world will be extinct, according to the prediction of a linguist from an American university. This means that what would remain will be about 600 languages. The reasons given for the possible situation are the inability of parents to teach their native languages to their children and because of globalization, as cultures tend to be fragmented when people migrate to new lands. The prediction was revealed by Dr. John McWhorter, who is a music, philosophy and American studies expert at Columbia University.
