> If you can't remember where your keys were four years ago, what makes you think our species will remember any event occurring within the last 50 years 2000 years from now? I also don't remember what I had for breakfast, so by your logic our spieces can't remember an event that happened last week? Nuclear waste repository is not an event, it's a building - have we ever lost the Pyramids or great wall of China? Has ancient rome dissapeared from the maps? Nuclear waste is stored underground in solid rock, if civilisations collapses, hunter-gatherers of medieval peasants can't get to it. It is likely that anyone digging kilometers underground into worthless rock probably knows what radiation is.
