haha I know dude.. I was just trying to lighten the very dark topic of total anilihation.
Its going to end when the US government tries to entrench its One world gorernment, and a bunch of people who actually like freedom try to fight it off. The Us will use Nuclear weapons, countries who oppose the US will also use Nuclear wepons - I dont know if this is going to be the end of the world or not... But it will be the end of civilization as we know it.
Of course, this implimentation of a single world government could easily be replaced by Energy wars, the likes of which we have already begun to see. That is wars to controll what little oil there is left of the planet. The country who controls the most oil will win, ofcourse. But not for long, cause when they dont have Oil to sustain themselves their society will also collapse... Wide spread famine and stuff... well you get the picture.
How the earth is going to end? Well... In a couple of hundreds of thoursands of years the Sun will die. As it dies it will expand. As it expands, It will consume earth in its firey circumfrance.
