Having English as everyone's first language would overall be beneficial for humans

In fact it's my first debate, so I'm not experienced myself either, in fact it seems like a great match. I will start by laying out reasons why I believe having multiple languages in the world is detrimental, and why I believe having English as a global language would reduce or make these problems non existent. Tourism: Tourism is mostly a fun activity and can be an enlightening experience. However I feel that language barriers can worsen the experience. Being able to speak to people less efficiently adds to needless stress on what should be an enjoyable activity, and can potentially be dangerous if a crisis happens and the tourist is unable to communicate, especially problematic if a child is separated from their parents. Additionally, it would provide business opportunities as it would level the playing field. The businesses that are richer and able to afford facilities for foreign language speakers have a significantly bigger reach and advantage than smaller companies that are not able to provide such a thing. It also discourages exploration, tourists are generally encouraged to stick to "tourist friendly" areas often because they speak English, this can make a trip to another country less authentic. Easier tourism would benefit anyone hoping to travel, and would financially benefit the tourist industry. Immigration: Immigrants would be highly benefit if they already spoke the language of the country they are moving to. If all people spoke English this would be the case. It would make getting a job, seeking aide from locals and integrating into society easier. People would have more freedom of choice when it comes to where they want to live in the world. This case is even stronger for refugees such as the people in the ongoing Syrian refugee crisis. They are forced to flee, have no idea where they will end up and cannot possibly learn the language beforehand. They are spread all over the place, and will often be forced to learn something like English, Greek, Italian or German upon arrival. Not to mention they'd be forced to learn it in unfavorable and urgent conditions. Speaking English would also lessen anti immigrant sentiments, poor communication can be frustrating for both parties, despite the immigrant's best efforts. Not to mention, non English speakers often don't often have the luxury of going to another country and having locals cater to their language. Culture: Culture could reach a golden age if everyone spoke English. The reason I say this is because instead of 339 million people, there could be over 7 billion potential people contributing to art in one language. This means that the amount of films, music, poetry, video games, literature etc. , would drastically increase. Not to mention culture would be diversify, because these things would be more likely reach places, in which the population would previously have no interest in. For example a book written by a Thai person would have a more equal chance of being successful in Britain when compared to a native Brit, so success would be more down to the talent of the author. Like with tourism, bigger companies have more resources to provide translations and therefore reach a bigger market, so not needing multiple translations would level the playing field. A lot of meaning can be lost when translated from the original language, having one language means consumers wouldn't lose out on an artist's intended meaning just because they live in a different region. Multiple languages in one country: Unfortunately some people can't avoid language barriers by simply remaining in one country. In countries such as Indonesia, Afghanistan, Switzerland, Canada and China, more than one language is largely spoken. This means that the organisations, businesses and governments have to allocate effort and resources into translating into all languages to reach everyone. Monolingual people find it harder to move around their own country, and in extreme cases it can contribute to ethnic tensions and isolation within some groups. People have to adapt to English: I believe I've made it somewhat clear that I think the people who would benefit most from English becoming a global language are non English speakers. This is because things are commonly translated into English, so people need to learn English anyway. In fact people who don't have time or resources to learn English are at a disadvantage compared to those who do. People wouldn't need to learn other languages: Finally, people need to learn other languages anyway. This happens all over the world so people from other countries will can speak to their neighbours. Japanese people will need to learn Korean, Polish people will take time to learn German, Mexicans will need to speak English. If everyone spoke English, no-one would ever need to take the time and effort learn another language. The only time this might not be the case is in the far future if dialects evolve so far apart they become separate languages. However people wouldn't need to take time and effort to make sure they could speak to other people, and could use that to develop other skills. Those are some of the ways I believe having English as everyone's first language would benefit everyone. I look forward to seeing what flaws my opponent can find in my arguments, or what additional points they can raise.
