Earlier this year I published a short article arguing that multi-parenting can provide a solution to a contemporary conundrum: on the one hand, many people are increasingly worried about climate change and environmental destruction. They know that having fewer children is, for a majority of people, the most effective individual action they can take to reduce their carbon footprint. Some women go on “birth strikes” – they decide not to bring children into the world. On the other hand, life without children can be terribly impoverished. Parenting may be the most important – and creative! – act one can engage in, a non-substitutable occasion for personal growth and, for many, the central source of meaning in life. (Which is not to deny that, for many other people, a childless life is perfectly fine.)
