English in a new world language order / leave your message

Some people say that english must be seen as foreign language and that it is possibly a way of union between continents. I agree that the status that the language acquired has to do with globalization, and that it changed the way people see the teaching of the language. On the other hand, I disagree when the author states that english nowadays is only a tool for comunication and is no longer necessary to teach cultural aspects or grammar.
