Most of the media today is led by the English language. A major chunk of the World Wide Web is in English. Television is led by English language channels. The best reading material is found in English.
In order to be able to succeed in life today, I think it is utmost necessary to be able to speak fluent English. Even in non English speaking Countries, English is being used as the major language of communication, especially on the professional level. Even other than the professional life, English is increasing becoming the mode of communication.
Since the world is getting smaller and smaller, and as they say its turning into a global village, one has to come into interaction with people from other cultures and countries more often. People from various Countries and even from different regions in the same Country usually do not understand each other's original language. There fore, they have to find a common mode of communication. A language that both parties understand, which most of the time is English. What I am trying to say that in today's world, where inter-cultural and inter-regional communication has become a necessity, the need for a common language cannot be overlooked. English is doing a good job as that common language.
