I think a lot about this. How on a geological timescale, most of our rubbish will be compressed down to a layer of oil with a bunch of increasingly heavy metals and radioactive isotopes towards the bottom. It'll be a rich vein for building a civilization for whoever comes along in half a billion years. (My bet is on the octopus).
