Will birthrates doom humanity? Tech billionaire Elon Musk sounded an old alarm in December when he claimed that declining births are “one of the biggest risks to civilization.”

“Please look at the numbers,” he implored the Wall Street Journal’s CEO Council. “If people don’t have more children, civilization is going to crumble, mark my words.”

In addition to the climate crisis, we live in a time of war, inequality, white supremacist violence, backlash against women’s rights, technological upheaval and fraying social networks. None of these dire conditions is a biological or ecological inevitability. Nor is human extinction.

To assert otherwise is to disavow responsibility for the policies and power structures that cause habitat degradation, income inequality and widespread injustice ― conditions that already threaten the lives of countless people and other beings on this planet.
