Well, there are vast amounts of highly toxic oil that we yet have to extract from below the surface - if something of that leaks by accident then it will poison and kill everything it will touch and it has been there since the dinosaurs died :-). Radioactive waste is solid waste and the amount is small - even if someone would dig it up, it would be only a local danger and it could maybe kill a reduced number of humans, but it will not be a global catastrophe. We are probably producing more highly toxic and poisonous waste that is not radioactive but it will also last hundreds if not thousands of years (e.g. toxic heavy metals) and kill many more people. Tens of thousands of people die every year from industrial pollution. How many people die from stored nuclear waste? Zero? (and even in worst case when a future civilisation digs up the nuclear waste - we are not speaking about hundreds of thousands like in case of industrial pollution).
