surely you have learnt from all the other thousands of 'end of the world' conspiracies ? the only accurate predictions we can make is , the tracking of an asteroid or similar object hitting earth ( and there isnt much danger for a few hundred years ) nucleur war ,global warming and of course our sun dying out ( wich it will eventualy , just like the other millions of suns that have died out .)
The end of the world will only happen to religious nutters, politicians, celebrity worshippers and the anti-pot goons. The rest of us will get to enjoy this earth and plant more when they're off this world.
