13．The time may soon come when we say goodbye to most of the world's languages．Today humans express themselves in over 6，000different languages．But that is quickly changing．Many scientists say that over half of these languages will disappear within the next 50years．After 100years，the languages used in the world will not be more than 20．Why？It is because people from different cultures live and work together much more often than before．This brings changes．The languages of the world's main culture are replacing the languages of the smaller cultures．Most international trade takes place in world languages such as English．People respect their own cultures and traditions，but when it comes to geting a job，knowing a world language is often necessary．It may mean the difference between success and failure．
Technology works on the change of languages in an even more amazing way．Modern media such as radio and television give young people in developing countries much knowledge about the world．But this knowledge doesn't come in words from the mouths of their parents or the elders in their neighborhood．It usually comes in the language of a different culture．
People in different cultures think it good for them to share a popular language．They can quickly share ideas and work together．Knowing the same language means easier communication and is a basis for trust．
Is the death of a small local language such a terrible thing？The answer is maybe．Many cultures may have words for many useful things we know nothing about．If their languages die，their valuable wisdom may be lost forever．The future of the world's language depends on our actions now．Will we protect endangered languages or allow them to quietly disappear？
Time will have the last word．
