The world will end when the sun burns it up.
Humans will mot be around to see that though.
So how do Humans die? When does OUR WORLD END?
It could be any number of scenarios previosly mentioned although humans methane is not a likely cause, even if we all farted at once. many of them will inevitably happen in time. The real question is, When will our world end? Some are saying 2012.
(Coincadentally The Nostradamus effect just came on on my TV while I was writing this)
I think that its clear that we have caused Global warming, and it is going to push our environment out of a human life sustaining climate. But this won't matter one iota if our world is destroyed in 2012.
Im not sure if this 2012 date will be our end, but if it is, I suggest this;
Go buy a Big 4x4 American Diesel Truck. Because It will keep you alive in a collision so you can live right up until the end.
They tell us that cars are the safest that they have ever been. Thank's to Unibody construction (Frame less) and high speed airbags. But I have seen these unibody coffins in the wrecking yards
and when the crumple zone comes for you... well have you ever cut your finger on a tin can...now imagine your in the tin can when a giant crushes it with a spiked bat. And what's an airbag on your steering wheel worth, when the steering wheel has pushed through your chest.
Get Big Trucks and live cause each of our worlds will end in our own ways. Don't rush the inevitable because you had to save a few bucks on gas.
