Я люблю изучать языки. Сейчас я учу русский язык.

Why do we learn the English language?

(Nothing wrong here, but unlike in Russian, we don't often refer to "English" as the "English language"... Simply saying "Why do we learn English" is okay)

It is necessary to learn foreign languages. That’s why pupils have got such subject as a foreign language at school. Everybody knows his own language, but it is useful to know foreign languages.

(pupils is not a common word, but okay. "That's why students have foreign languages as subjects at school.")

I learn English, because I understand that I can use it. For example, if I go to England I’ll be able to speak English there. If I go to the USA, I’ll speak English too. English is used not only in England, but also in other parts of the world.

("I'm learning English because I know that I will be able to use it often" could be a way of rephrasing this. "English is not only used in England," both my change here and what you have are possible, I'm just showing how it could be rephrased as an example.)

I learn English because I want to read foreign literature in the original. I know and like such English and American writers as Charles Dickens, Mark Twain, Lewis Carroll and others. I understand that I must learn English. If I know English well, I’ll be able to go to the library and take books by English and American writers in the original.

("I am learning English" would sound better, "I know and like" sounds a bit strange, maybe, "I"m fond of English and American author such as..." Next, "I understand that I must learn English" could be, "To do this, I must learn English."  When you say "take books by" we use a phrasal verb, "take out" so, " I'll be able to go to the library and take out book by" or simply, "I'll be able to take out books from the library by..." 

I like to travel. But it is difficult to visit countries, when you don’t know the language of these countries. If I know the language of the country, where I am going to, it will be easy to travel there. If I want to ask something, I can do it in English.

("If I know the language of the country I am going to, it will...." delete "where," then "If I want to ask something" —"ask something" is a little strange, maybe just "ask a question.")

I like to read books. And I like to read newspapers, too. If I know, for example, English, I’ll be able to read English newspapers and magazines. Knowledge of foreign languages helps young people of different countries to understand each other, to develop friendship among them.

("...young people from different countries understand each other, and ..." —delete "to understand.") 

You can see a lot of advertisements, signboards, names in the streets. They are in foreign languages. Very often they are in English. If you know English, you can read and understand them.

Now we buy many clothes from other countries. If you know English well, you can read something about the size of this or that thing. It is clear for you what it is made of.

("These days we buy many clothes" rather than "Now.." "you can read the size of the item" —delete "something about," and I would add the conditional in the next part, "It would be clear to you what it is made of."

There are a lot of films in foreign languages. If you know them, you can understand films without any help.
There are international friendship camps in the world. If you can speak foreign languages, it will (would) be easy for you to visit such camps and speak with the boys, girls, men, women who do not know Russian.
In short, I understand that I have to learn English in a proper way and I try to do it.

(Good use of, "In short" maybe the next part could be, "I understand the benefits of learning English well and I want to continue improving."
