In other words, people may easily organize their trips around the whole world because of no linguistic challenges. Briefly, the only language can help misunderstandings to be eradicated among humans. Moreover, it can help to spread trade between nations. Statistics show that, for example, by having the only language in the world, tourists' visits will increase dramatically by almost 15 % between countries.

One possible drawback is that it will directly affect some jobs, including guides, English teachers and translators, in a negative way. To be more precise, if states agree that people utilize to communicate with foreigners in one language, they need not attend to English courses and do not need translators’ service so as to communicate to people.
