English

I think learning English should be basic for everyone.

Because it is the language most spoken in the world.

The English can serve you for many things.

For example, if you travel around the world, you can communicate with most people. (That's why I think everyone should learn to speak a minimum).

Also, the jobs, they demand to know English, for being such a general language.

For example, a high level language is needed at campsites, especially in the receptionists or information points, not only in English, so when people go to ask any questions, you will be able to respond.

Also, a lot of information on the Internet and books are in English.

In short, the world in which we live, we need the English, it is very important.
