hey i just had a comforting thought: all that nonbiodegradable crap in landfills will probably eventually get subducted and then it won't matter.
of course there are still rocks around that are like a couple billion + years old, so it could take a while
maybe this should be how we dispose of waste: we can just send it down a chute right into the earth's molten... uh, not core, but whatever you call the thing the crust is floating on again.
and then we can surf the earthquake waves.
i wonder what riding a tsunami would be like. that would rule, if there was a way to get out of it before you crashed on the shore and died.
