One of the most remarkable trends of the 21st century is the dominance of English as a global language and standard of communication among countries. It is not a secret that some people are concerned about the impact of this phenomenon on the diversity of languages. Nevertheless, it is the view of the author that although English may bring up many challenges in preserving indigenous cultures, its advantage will continue to outweigh its disadvantages.

English nowadays has become the most popular choice of communication between people with different backgrounds, especially in the domains of business and media. With the growth of English as a common method of delivering information, people are able to overcome communication barriers and reduce misunderstandings. So it facilitate the cooperation between countries in many areas.

Some may argue that the flourishing of English in global context can only come at the expense of other languages, which subsequently, put other cultures at the verge of extinction. However, this notion is flawed as people do not have to give up their mother tongue to be able to learn English. Additionally, it is not necessary to master English for sufficient day-to-day or business communication, which requires only an intermediate level of the language. In fact, knowing two or more languages is an utter advantage for the speaker, especially in today globalized world, where multicultural environment is highly promoted.

As outlined above, one shall never consider the proliferation of English as a threat that is posed to other cultures or languages. Alternatively, it should be viewed as an extra tool for communication or a mere advantage for the speakers.

++English is spoken in more countries than almost any other. 

--English has horrendous grammar, making it difficult for non-speakers to learn. 

PROS

Increased employment options. Staffing agents read thousands of résumés per year and bilingual applicants are routinely at the top of the pile. According to Regis Canning, a staffing agent at NYC staffing firm Temp Agencies, seeing "fluent" on a résumé piques the interest of employers, and shows that a candidate "is smart and skilled with languages." Those perks make employers hire bilingual job seekers more often than not—even if language skills have nothing to do with the job.

Social circle expansion. Employers aren't the only ones who find more than one language irresistible. According to a 2004 poll, 97 percent of dating agencies asked applicants if they spoke a second language. These people-experts know that speaking a second language makes you look more worldly, intelligent and affable than English-only speakers. That social leg-up opens doors and opportunities that might otherwise be closed.

Cons

The older you are, the harder it is. Let's face it—all most of us remember from 4 years of high school Spanish class are basic phrases like baño and gracias. However, that failure to retain foreign words may not be our fault; we may have missed our window of opportunity to learn languages easily. "Young children can acquire native-like fluency as easily as they learned to walk" says Leslie Lancry, CEO of Language Stars. Schools like Language Stars capitalize on this window and are able to teach children a new language simply through immersion. But according to Lancry and other experts, this window closes around age 10. After that, even years of tutoring may not make a language stick.
