Banning English is a terrible idea. IT could never work. It would be much to difficult to get everyone to learn a new language. It's much the same reason that we dont switch from the english standard to the metric system. It would take too long and no one is comfortable enough to make that switch. You'd have to convince the whole country that what you're doing is better than what you're leaving. and then also convince everyone to learn it. THe amount of time and effort that would take is insurmountable.The benefits wouldnt even grant us that much. Switching to the metric system at least would give the world unity because were the only ones who are stubborn and wont change like the rest.
