Interesting stuff, Dave.
I haven't read the disease link (or book!) yet but hope to do so soon (if I don't get distracting reading Explain Like I'm Five (ELI5) or thinking up T-shirt slogans ("TEOTWAWKI is a nice place to visit but I wouldn't want to live there", "TEOTWAWKI: Like Milwaukee but less cheese", ...).
It sounds like the designers of nuclear power stations don't follow the old adage "hope for the best but plan for the worst". They're not the only ones. A lot of people only plan for the best or near-best; well, it's cheaper that way
(but I'm probably as guilty of this as most people).
(Incidentally, my Firefox browser couldn't follow that link to ELI5 until I told it that, yes, there is a '/' after 'comments'.)
The diagram at the start of your blogspot article is interesting. I hope we don't reach TEOTWAWKI during my lifetime (I'm 51) but we do seem hell-bent on getting there
Most people seem to believe (or act like) all the resources we're using will last forever. Yes, I know
it's nice to have cheap oil-based products (for example) but sooner or later they're going to get a lot
(That's enough frownies for 1 message!)
