Maybe that claim is off base, although I wouldn’t expect that to be the overt media story anyway. More of what a typical 35-year-old upper-middle-class liberal “childfree” couple would ramble about to their friends when they’re justifying why “actually, not having kids is the green thing to do.”

Now that I think about it more, I shouldn’t have included that in my Europe hypothesis, as I’ve heard that kind of thinking in general but not more from Europeans.
