With 6,500 languages spoken in our world today (English being only one of them), we rely on people who are able to read, write, listen, and or speak two or more languages to translate & communicate information in order to keep our world connected. If you think about it, you wouldn't be able to watch Japanese anime if it weren't for people who either dubbed or subbed it from Japanese to English (or another language). The same goes for Korean dramas: unless if you know how to listen to & speak in Korean, you wouldn't be able to understand a word of what the characters are saying without any subtitles. In today's climate, being bilingual not only allows you to be more attractive to an employer, but it also allows you to connect & communicate with others that know & understand the same language.
