Some of you are old enough to remember the 1960s, when books like “The Population Bomb” warned of coming mass starvation if people didn’t stop having kids. And some folks took that warning seriously and decided to forgo childbearing.

Places like China with its brutal, obscene “One Child” policy forced people onto birth control after one child (and aborting any further pregnancies) while none of the predicted famines occurred. 

Fast forward 50 years and while Africa is still booming, demographic drops in places like Japan and Korea are at near-crisis levels; China’s population is aging faster than anywhere else and half the world’s nations have fertility rates below the replacement level of two children per woman. 

Now there’s another reason not to have kids: Climate change. The New York Times tells us why:

It is not an easy time for people to feel hopeful, with the effects of global warming no longer theoretical, projections becoming more dire and governmental action lagging. And while few, if any, studies have examined how large a role climate change plays in people’s childbearing decisions, it loomed large in interviews with more than a dozen people ages 18 to 43.

A 32-year-old who always thought she would have children can no longer justify it to herself. A Mormon has bucked the expectations of her religion by resolving to adopt rather than give birth. An Ohio woman had her first child after an unplanned pregnancy — and then had a second because she did not want her daughter to face an environmental collapse alone.

Among them, there is a sense of being saddled with painful ethical questions that previous generations did not have to confront. Some worry about the quality of life children born today will have as shorelines flood, wildfires rage and extreme weather becomes more common. Others are acutely aware that having a child is one of the costliest actions they can take environmentally.

I’m glad they involved someone from a religious background and a Mormon at that, because of Latter-day Saints’ doctrine encouraging large families. Another few paragraphs later:

Parents like Amanda Perry Miller, a Christian youth leader and mother of two in Independence, Ohio, share her fears.
