'Paradise' is a classic case of Utopia gone bad. Why do you think we're so fascinated by the idea of a perfect world ruined? (It is after all perhaps the oldest story).
Jason K. Lewis
I think it is a case of fiction mirroring reality. The world (or nature itself) was a form of paradise until we came along. We live in a world that is being, from the perspective of nature, ruined. Maybe we're fascinated by it because we see it happening before our eyes and do nothing about it- it's much easier to bemoan the idiocy of it happening in a fictional world I guess?
