The planet is dying. Our earth’s climate has reached a point where it can no longer regulate itself. Fires, floods, and natural disasters are sweeping countries across the world. What does it mean to be a child citizen in the Anthropocene? Can we teach children a posthuman civics that can care for the more-than-human world? Extending on the concepts of ’little publics’ and ’posthuman citizenships’, this book progresses these notions with a view to modelling, and better understanding, posthuman publics and civics. Using experimental methodologies, the authors develop original, robust ways of understanding children’s subcultural civic practices founded on care for the more than human.
