Is the need to learn more languages increasing or decreasing? Give a reason for your answer.

increasing, this is what i note from the communitty and from my colleauges, some likes travel to another countries so they learn the language of that countery, some to increase knowledge and other to get more benefits from work.

Overall it is certainly increasing; a common market arguably requires or at least encourages a common language as it facilitates business. More specifically, the demand for certain lanuages (i.e. Mandarin) is definitely going to increase. Most interestingly in my opinion, english speakers will likely be forced to begin learning these other languages to gain a comparative edge. 

I think it increases due to mass communication means.I can have a friends all over the world who speak different languages.so I can know their language.Also , in business , you can have clients everywhere.
