A personal opinion piece!
I think that learning at least one other language in addition to your native language should be compulsory. Therefore, simply the Departments of Education around the world must invest in language education.
I am lucky in that I have an affinity for languages and learn them quickly, just lucky I guess. It was like that when I started to learn French and it was like that when I learned Vietnamese. The problem with language is that if you neglect them you lose them! You might re-acquire them quickly but without continual use and practice the languages slowly disappear.
I have just started to re-acquire some of my previous French and Vietnamese language skills and have started to try and learn some Arabic. I have also decided, for personal reasons, that I would like to learn Balinese.
Why should language be compulsory? Simply, because there is so much of a peoples' culture tied up in their language. Perhaps if we knew the languages of others we could better understand their cultures, the things that make them tick, their views on the world, and their outlook on life, perhaps then through understanding we may find peace in our time!
Forever the optimist :D
A good week to and for all!
