If people most concerned about climate avoid having children, the next generation may inherit fewer traits linked to long‑term planning and environmental concern.

Over time, this selection effect could make pro‑climate norms and policies harder to sustain. — It reframes climate ethics and policy by showing that self‑selected childlessness can undermine the very social traits needed to address long‑run environmental challenges.
