Environmental effects, at least, do seem to follow a sigmoid.
In most respects the US and Europe do less than they did
20-30 years ago. At least some believe we will knock
ourselves off without obliterating the biosphere and the
amount of biodiversity available then will have a significant
effect on that available post-knock. Most are shooting for
a giant reserve policy - they think humans will or can reserve
vast areas for natural evolution and leave them that way
forever.

Dr. Jackson was obviously very upset by this scenario, so, no
I didn't discuss the possibility that it could be even worse.
Remember, although they might agree with you on the
predicted outcome, to them it's a horror scenario!
I only broached such subjects with a few people (none of the
ones who were discussing human-dominated ecologies)
and they were generally not receptive on limits-to-growth
grounds.
