If you are moving to an English-speaking country, then learning the language will help you to fit in better when you do move there. In the United Kingdom and United States, although there are many different ethnicities, day-to-day life is conducted almost solely in English by government officials, the police and people working in administration. Although other languages are spoken throughout the U.K. and the U.S., if you are to succeed in the country you will have to learn English.
Internet, film and television have played a major role in making English the language of popular culture. The biggest grossing films all come from Hollywood, and according to Antimoon more than one billion pages on the Internet are written in English. Popular music, whether from English-speaking countries or not, tends to be in English, meaning that if you want to understand the modern trends in popular culture, you will need to learn at least some English.
According to Antimoon, 95 percent of the world's scientific papers are written in English, even though only half are produced by English-speaking countries. This means that English is the predominant language of science. Words related to modern technology, such as "computer" or "Internet" are universal words which have their origins in English. Further developments seem to be following this trend, meaning that in the future, new inventions related to technology and science will most likely be named in English.
At International gatherings, the language spoken is invariably English. At the United Nations, the Olympic Games and NATO, English is the language used to communicate. According to Antimoon, 1.5 billion people in the world speak English and 1 billion are learning, meaning that more than one in three people in the world speaks English at some level. This means that if you are engaged in any sort of international activity, you will almost certainly be required to speak some English.
