Nice poem but it doesn't mean much. This item that spent nuclear fuel is a problem for 100,000s of years is mis-information. Only the plutonium lasts that long and the plutonium will eventually be too valueuable as a fuel to leave alone. The processed nuclear fuel will leave behind a small urn of ashes per person in a nuclear economy. Your ashes occupy a small urn as well and that will be your legacy, your foot print.
