MARVEL: The potential of guilt to remove carbon dioxide from the atmosphere is basically zero. I’m not going to police how anybody feels, but I’m not convinced of the efficacy of guilting or shaming people. Whether or not you have a kid, your moral responsibility is to the children who exist in the world. And even though presumably none of our children are being separated from us at the border, none of them are being mistreated, we each have a responsibility to those children. I feel that way about climate change as well.
