Many people think that it will be a good idea if there is only one international language. Others think there should be more than one. So, who is the right?
To begin with if people used only one language, communication would be much easier. Furthermore, translators would be absolutely unnecessary, because if everyone spoke the same language, we would all get along well.
On the other hand, people could stop using their languages and in that way they would lose apart of their culture. Another thing is that probably many people would not speak the language well and they would not always understand everything. It is worth remmembering that native speakers would have an unfair advantage.
From my point of view, there should be more than one international language, because we don't want to lose our own languages. In addition to this, Esperanto was not so succesfull.
