There’s an interesting article at New Scientist that imagines what would happen to the earth if all humans disappeared today. The most basic conclusion is that pretty much all traces of human existence would be gone in 100,000 years.
Equally interesting is the discussion of this topic on MetaFilter. As usual, the MeFi discussion goes in many different directions, but I sense in some of the posts an unease that traces of the human race could be erased so quickly.
