This afterword proposes a system-theoretical synthesis between critical ecosophy and critical peace studies as a foundational framework for addressing the intertwined global crises of ecological collapse, social inequality, and systemic violence. Drawing on the ecological systems theories of Gregory Bateson and Félix Guattari, the authors explore the convergence of environmental, social, and mental ecologies with the holistic aims of critical peace philosophy. Positioned in the context of the Anthropocene and escalating apocalyptic risks, this synthesis offers an integrative strategy toward ecological civilization, grounded in educational resilience, systemic thinking, and participatory ethics. The work examines how ecopedagogy, ecological democracy, and transversal subjectivity can disrupt the logic of Integrated World Capitalism and reimagine human-nature relations. It contrasts competing geopolitical paradigms—America First and China’s Ecological Civilization—as divergent futures in global governance. The afterword concludes by advocating for a planetary ethics of peace and sustainability that mobilizes educational institutions, postdigital epistemologies, and collective agency in the face of collapse and transformation.
