I’m glad to see this question becoming more public. Though it seems to still be considered radical. It is one of many factors that went into my (and my wife’s) decision not to have children decades ago.
P.S. I should really correct my statement above. Neither I nor my wife ever really wanted children. But, while we were still of breeding age and before my vasectomy, when we’d hear a wailing infant, we’d make comments like “Reason number 837 not to have kids.” But, we’d also make comments on hearing about overpopulation or some environmental crisis, especially climate change and ocean acidification, like “won’t be our kids dealing with this.” Actually, we still make such comments.
