This dissertation offers a philosophical analysis of the ecological crisis through the lens of Hannah Arendt. It frames the ecological crisis as a struggle for situated cohabitation. By analyzing the work of Arendt, this dissertation shows the ways in which the ecological crisis is entwined with the political crisis of plurality. I suggest that these two issues are interconnected and that we need to address both for situated cohabitation. This dissertation is an interdisciplinary work, drawing from environmental philosophy, feminist philosophy, and educational practice. The work is intended to provide novel insight into the current ecological crisis in three ways. First, it grounds its theory in the work of Arendt, a thinker not usually situated in the prevue of environmental scholarship. Second, by synthesizing Arendt's account of plurality with the work of Judith Butler and Ricardo Rozzi, this dissertation explores a politics of plurality that can take account of social and ecological conditions of plurality. Third and finally, the dissertation merges theory with praxis by offering a practical program for doing environmental philosophy with children, a program derived from my sustained experiences working as a facilitator of a philosophy for children (P4C) program.

Riverine avulsion is a radical divergence of a riverbed. In this dissertation, I take this movement as a paradigm for understanding the features of radical change. I develop a model for understanding the essential features of radical change. I argue that the main features involved in avulsion are tension, abandonment, and material freedom. In my analysis, tension provides the catalyst for change, such that it pressurizes complex systems of organization to the point of collapse. I use Catherine Malabou's work on denegation to understand the collapse of a system as an accident; the rupture of a system entails that it is no longer affirmed nor negated, it is abandoned by the process of becoming. Utilizing the work of Deleuze, I present the moment of rupture itself as the moment where materiality breaks free from the restrictions of an organizing system to becoming consolidated into countless new forms of organization. In my analysis of the ontology of avulsion, I employ a new materialist process of becoming to capture the complex networks of relations involved in the moment of creation. I challenge these Deleuzean and new materialist fields of philosophy over their affinity for affirmation by integrating accidental abandonment. Finally, I propose …
