Utopia is the theory that if humans are given enough time they will eventually create a perfect world; a place so unrealistic that it can only be in your dreams. In a utopia everything is serene and free of any and all problems imaginable, but it is a place that doesn’t exist. Every utopia has faults which makes it a dystopia. Not everyone will agree in a utopia which will cause chaos, thus making a utopia an unfeasible thing.
Ex. Neverland, from Peter Pan. It seems perfect there, to be forever young is great, to have no supervision is what every kid wants. But the utopia becomes a dystopia when the lost boys realize they might want to grow up, the problem of captain Hook, and when their leader/friend, Peter Pan, might leave.
