Almost no-one has english as first language in EU. Also most younger people speak at least 2 languages. Only older folks and people that lives in rural areas speak only one language.
I know. I am European. I've been bilingual my entire life. Today I speak four languages. The point was not that speaking two languages is enough, what I meant is that I believe having more languages around in general increases the diversity also of our ideas and thoughts. That is why I, today, feel like protecting languages have a very valid point.
