Have you ever considered a world with people talking the same language? Probably it is really difficult for someone to think about it, due to the fact that we have million of languages and dialects nowadays. However it is worth to dicuss about it.
In the first place th idea confuses us, but with a more carefull look we can make out the advantages of this statement. First of all imagine yourself in to china, dream talking to these people with the odd eyes and the difficult language. You would learn about the cultures you want with more ease. Just fancy that! Moreover you would be able to encounter and communicate with more people, and who knows? You may make more friends and whoever finds a friend, finds a treasure. Last but not least you will stop spending your money and time to schools in order to learn a new language.
On the other hand there are many disadvantages of having only one language existing. For instance everyone would be the same as none of our planet''s country would be different from the other. Furthermore our culture would disappear in the course of time so there would be no interest for learning each other or travellin to another country.
Well the fact that everyone could be speaking the same language attracts the most of us. However this is very difficult to achieve nowadays, but even if something like this happens, many thigs will be changed.
