Rawls, I think what you are keying in on is pure fantasy. People work in cubicles and go home at night to couches and television sets or computer monitors. There is a major disconnect between people and nature. I think much of the fixation on the crumbling of civilization you have noticed stems from simple fantasy about connecting with nature in the raw. Look at the popularity of outdoor survival shows and the like. If everything came down around our ears, the things that disconnect us from the world are immediately removed. I think what you see is a subconscious desire for that, nothing more. I do not think many people really want to see "the end of the world". I do think many people are somewhat dissatisfied with the banality of modern existence and are at a loss about what to do about that.
