I have read many books that deal with futuristic societies, and many of them, including some famous series with teenagers/young adults*, show a Global Earth. A Earth without a United States, Russia, China, Afghanistan, but just 1 huge Empire. I know that these are serious fantasy books, but they have actually brought up a discussion at school before (multiple actually) about if boundaries will ever change, if maybe people will blend into one huge nation of its own. I am just wondering what others think about this. I could see it happening, but many years down the alone. Old rivalries die hard. My family still holds a grudge against England for persecution from over 200 years ago, but people change. I believe people can unite, just takes time, and effort. *Halo Series, Star Wars, Star Trek, etc. P.S. Yes, I realize all of these are very fantastic series' but they all have a basic point of a united Earth.
