2012 or however whenever?

I have read Musings of an Over Active Mind by Due for a Miracle's "Mass Extinction" post. I was thinking myself, will their be a decline of the human race in 2012 or farther than that? I was thinking that we are going to die, but when are we going to die? Only HE knows. HE can choose whether to kill us or just stop us from growing any longer. I'm scared what end the world would come to at 2012 or later than that.
