The majority of films and entertainment programs in the world is in English. Not to mention that the primary language that books are published in is English. The wealth of information and entertainment that the world has access to is primarily in English. It always feels like an accomplishment for an English learner to be able to watch a movie in English with no subtitles, or read their first book entirely in English.
Ultimately English makes it easy to access and understand other cultures. When the language barrier is lifted, there is more space for cooperation, for empathy, and for common ground. It would seem that having one language that most people understand and speak does not leave much room for variety, but in reality, it actually offers an opportunity for everyone to participate, to let their voice be heard, to actively exercise their freedom.
