good one!
I don’t know why we still have trains, cars, planes, etc.
Interestingly, there are few deaths attributable to the radiation issues at Fukishima. Over time it is clear there will be more deaths, mostly due to cancer. on the other hand, the death toll will not likely reach the 15,000 that died in the actual earthquake.
Fukishima is a great example of the worst disaster that could happen, with stupidity abounding and multiple separate failures, and yet while it will be enormously expensive, it doesn’t make the list of major disasters (a lot more people died when the planes ran into the WTC, which I guess would argue for banning planes as you mentioned).
Fukishima was not anywhere near as bad as Chernobyl, which of course was the result of a police state which cared nothing about safety.
in terms of theoretical damage, nuclear is up there, but conceivable disasters with nuclear plants do not show casualties rates near the conceivable disasters that could befall our major dams. If I had to pick a place for a 50-foot diameter meteor to hit, I would choose a nuclear power plant over a major dam.
