Learning new language is hard. I know that. It takes time, effort, commitment and any progress is really hard to see or test. Many of students try to start with new language, but they will be soon disappointed with his difficulty, grammatical rules and lack of vocabulary. They are also not sure, why even they should learn new language in first place. In regular environment, there is not many possibilities how to practice your new language and even if there will be, it's hard to practice it regularly.
The limits of my language means the limits of my world. Ludwig Wittgenstein
I recently see some results from EU barometer. In year 2005 in Czech Republic there has been about 61% of residents to be able hold conversation at least in one addition language. In year 2012 there was drop about 12% to current 49%, which is not much. There is also interesting number, that only 27% of responders can speak English language and about 14% can speak German. If we take in account, that subjective scale of each responder is probably very differed and language without active usage is going to be forgotten really soon, the numbers are really bad.
