This concluding chapter begins with a reflection on Paradise Lost, and draws a parallel between John Milton’s meditation on loss, responsibility, and ethical living and contemporary educational imperatives to foster care, relationality, and planetary responsibility. It also ponders Hannah Arendt’s concept of amor mundi—love for the world—the chapter examines how education can become a space for both preserving and renewing the shared world. It provides an overview of contributions to the volume, and highlights how philosophical, pedagogical, and pragmatic narratives intersect to foster transformative forms of sustainability education. Ultimately, this conclusion to the edited collection argues when the contributions are taken together, they show that sustainability education, when grounded in care, plurality, and openness to the unforeseen, holds the potential to resist extractive logics and nurture liveable, just, and flourishing futures for all.
