Languages today

A fever to learn new languages is a phenomenon that is has extended all around the world. All of us, in major or minor measure, have the necessity or curiosity to know a new language. This is a characteristic of a global world, one positive face of a globalisation. Languages permit people to approach people and universalize some common ideas between cultures and societies. But one interesting question would beis "Why do we learn a new language?" What Which is more important for to us, necessity or curiosity? For example I started to study English because of the possibility to improve my job propects but later (the English language liked me more) (OR I liked the English language more than I would never have imagined. Perhaps (my case is not the only one). (i´m not the only case)
Also it would be interesting to think about what will be the language in the future. I have two in mind, English and Chinese because of the most powerful countries in the world is always which extends their language and culture. In the past, the extension of the languages have always been achieved by using the violence or the strength. Fortunately now the forms methods have change, the languages spread due to the economic development. Perhaps money is the only vehicle to achieve an only a global society with only one language. For this reason, learning a language will not only be a hobby but a necessity for millons of people.
