"Describe one aspect of the natural world that you are very curious about, something you have wondered about but something you don't have an answer for. Describe this phenomenon in as much detail as possible and explain why this phenomenon peaks your interest."

One thing about the natural world that I am curious about is the end of the world as we know it. Biology or not? Does man tie into it? It sounds corny or crazy, but I am actually an avid believer in the "2012" prophecy or theory; the beginning of a new age. Drastic believers see the world ending as a literal sign, but I see it as a sign of great change in the world. I am curious though, how will it happen? Will the extremist radical believers be right? Will the earth's magnetic poles begin shifting? Or will a series of natural disasters begin to occur such as volcanic explosions and extreme tidal shifts? I know this is a slow process with extreme results, but I am very curious, will we be able to survive if this takes place? Another ice age? I think so. I know it may seem a bit off topic, but I see much to answer about life in this question. Survival, evolution, adaptation. All of these will take a lot of consideration and thought as the time approaches.
