English will never dominate the world.

English will never dominate the world. It'll never replace other languages because it forces other countries to adopt English cultures. People want their own culture and their own language. They only need English in business, sometimes.

We live in small world, globalization is all around us and whereever we go somehow we will be affected by it.

However, every nation wants to have their own identity, their own culture and languages as well. On the other hand people want to contact each other so they can exchange views, development in different fields. But that could be impossible if they do not have same languages .

And in my opinion English can be the international languages, it is easy and there are a lot of countries where English is the first or second language.
So it is not wrong to learn, speak and use English. It will never going to cancel any other languages.
