Importence in knowing more than one languae

I think that it is very importent to know more then one language so you can expand your knowlede and speak to more people. If you were to only speak one language you are very limited today in the united States with who you can talk to, because more and more people who dont speak english come here everyday. But if you were two speak  two diffrent languages you would be able to commincate with more than one type or ethnicity of people. I also think that if you learn a new language that you are more into there culture and look more into and understand about the people and their language.
