Sounds like good darwinistic filter to me. In this case it will filter out people who are so afraid of the future that they want to rather have mankind extinct.
Sounds also like a Darwinian theory to me.
Never mind people who can actually see the writing on the wall I guess, just keep breading during a totally unmitigated environmental disaster and see how that does for your offspring.
I know for a fact this issue turns people off having children.
