No doubt that learning languages takes up a lot of time. That is why some people think that it would be better to have only one language on our planet. But will it be really beneficial for mankind?
In my opinion, the reduction of the number of languages is a disaster because it will totally destroy our great cultural heritage. With each loss of a language comes a loss of a culture, a loss of a way of life that deserves to be protected and treated as valuable. I also believe that leaving one language for communication will greatly reduce the linguistic diversity of our planet, which is the key to our survival. What is more, it will be rather difficult to choose which language to use and it may even lead to wars.
Many people think that if we have only one language, communication will become easier and there will be no need to learn foreign languages. I cannot agree with them because knowledge of foreign languages makes a person educated and well rounded. You cannot broaden your mind if you see the world only from the perspective of your own culture. Besides, people are a lot more helpful if you speak their language.
