So you are buying into all this too?
To tell the truth, I don't know what will happen in the future. If I did, I wouldn't be on getbig right now, I'd be on a yacht...
Man is always obsessed with his own mortality, his own ego. And when there are events that happen out of his control, man's imagination gets the best of him. Top it off, in a capitalist society, people will try to make money off of anything---especially the end of the world.
I also believe that the Western World, particularly the US is going thru some serious issues, we've lost balance, and are on the edge of decodance and a everything is normal vibe, instead of structure, guidance, and humility. In nature, when things are left unchecked or unbalanced, chaos ensues.
Over-run by rabbits, mice, deer, etc due to no predators? Then the flora takes a hit.
I firmly believe that this "end of the world" stuff is that man's collective conscious know that something is going on with itself---and people are scared of the unknown.
But, like the saying goes "Tomorrow is not promised."
