6.There are over 6 000 languages in the world today, but experts have published a study which predicts that more than half of these will become extinct within the next hundred years. They give three main reasons why these languages are in danger. One reason is invasion. Countries take over other areas where people speak a different language. This means that the people need to start speaking the language of their new rulers. Another reason is migration. This could be because of war, disaster or the search for work. When they move to a new country, these people need to learn the local language. Because so many people speak these languages, they have become the major global languages in business, films, music, and the internet. This means that even more people want to learn them and, as a result, they become even more dominant. English, for example, is now spoken as a first or additional language by over 1 billion people – nearly a sixth of the world’s population. This dominance clearly causes smaller languages to die out. Some people think that this is a good thing. They say that communication will be easier, cheaper and quicker. Others believe we should protect endangered languages. These people believe that when a language dies, many of the traditions of the speakers are lost too. They argue that we can use the language to learn a lot about the history and culture of the people that speak it. How many languages will die out according to some experts?
