TED Mark Pagel - How language transformed our humanity

I'm going to answer the question "What do you think about the fact that there's a dilemma in our modern globalized world. Whether to keep our 7,000 or 8,000 different languages or make the world as one world with one language.'

Well, I think that has some negative and positive sides. When everyone is going to change their language in the same one, teachers which teach people foreign language, will lose their job. Everybody is going to be the 'same' , there is no challenge anymore to learn how to speak another language with which you can communicate to foreign people. On the other hand, it'll make it easier to trade with eachother. When people speak the same language, there will be less of a barrier to understand eachother. Plus the fact that, like Mark Pagel said during his speech, the European Union will have to spend less/no money on translating all the reports into 23 different languages. This will save them billions of dollars! The money used for the translations could be used for Greece right now (for example).  I'm not supporter of the idea to make one world with only one language. It's hard to let all people adapt the new language. Besides, I think different languages are pretty much interesting!

There will be people who think: "YEAH! This is an amazing idea!". How will you change the language of people who live in the bush bush? Mark Pagel's speech was quite interesting, I'm wondering how different people think about this dilemma.
