That is a taster for something I've been thinking about lately and haven't seen anyone else commenting on.

We appear to be headed for catastrophic global warming with all the world's ice melting. That would push sea levels up by about 200 feet, and the rise is likely to be accelerating in metres per century.

Most of the world's nuclear power stations are near sea level and will be inundated in a century or so. Nuclear waste stores like Windscale pose an even more extreme hazard.

So. We already have a mass extinction on the way from climate change and habitat destruction. Now add the likely effects of ALL the nuclear waste humanity has ever made being let loose into the global ecosystem - any survivors of the collapse of civilization will have no way to stop it.

What would survive? Any multicellular organisms at all?
