At the very time that I was reading Jan Newberry and Rachel Rosen’s “Women and Children Together and Apart,” young people around the world were organizing collectively to demand action on climate change. On 15 March 2019, children and youth in more than one hundred countries walked out of school in a coordinated act of defiance. Gathering in parks, public squares, and on the steps of government headquarters, their signs and chants decried the intergenerational violence of planetary destruction, demanding accountability from the world’s most powerful. As these young people make clear, the climate crisis is very much a crisis of social reproduction: the environmental devastation wrought by capitalist accumulation threatens the conditions for making and sustaining life, with particularly devastating consequences for the world’s most marginalized. In their organizing to demand political action to address this crisis, young people have shone a light on the multiple temporalities at stake: by withholding their labor as striking students, they refuse to produce value for a future that is increasingly under threat.
