why don't you track 'em down and ask them?
That's why I say I don't think we're heading to that level of disaster. It took hundreds of years before we could explain why the Norse crops stopped growing and their herds stopped having enough pasture to graze. These days, however, there is money to be made in environmental friendliness. When oil becomes too expensive, it will finally be economical to use alternate energy on a large scale. If they have the phrase "10000 years" in their summary, though, it doesn't sound like they deal exclusively with industrialized societies.
Without having read the book, I make the following prediction: its thesis applies whenever we can identify a problem and we have the technological means to solve it. It's when one of those two statements are false that we get problems like the ones I mentioned. It sounds like an interesting book and I'll give it a read.
Did you mean I should track down the authors or the Incas? ;)
