This article presents a reflective analysis that utilizes Hannah Arendt’s concepts to rethink utopias, examining how youth climate activism embodies her ideas of freedom and public action. It proposes viewing utopias as spaces for ongoing political engagement rather than as fixed visions of a perfect society. Grounded in Arendt’s critique of totalitarianism, the study highlights how young activists respond to the climate crisis through collective actions that express political freedom. By focusing on the youth climate movement, the article presents activism (...) as a resilient alternative to rigid solutions, fostering new possibilities for justice and environmental change. Arendt’s concept of natality – representing new beginnings – connects with the hope-driven nature of youth movements that reimagine the future through collective action. Ultimately, it argues that, in an Arendtian sense, youth activism cultivates conditions for freedom and transformation in the present rather than merely pursuing a distant utopia. (shrink)
