In the face of widespread environmental and social destabilization and growing uncertainty about the future of humanity, this collection of essays brings the philosophical tradition of phenomenology to the question of relations between generations to examine our ethical, political, and environmental obligations to future people. Emphasizing phenomenology's rich reflections on the role of time in the constitution of the social-historical world and its relation to the environment, the essays interweave the central themes of mortality, natality, generativity, and amor mundi to build vital bridges between new developments in both eco- and critical phenomenology and important work in intergenerational ethics. Together, the chapters reevaluate the traditional scope and foundational concepts of environmental ethics and social justice, paving the way for a revised understanding of intergenerational responsibilities, culminating in the key insight that future people are of us. The result is an invaluable conceptual toolkit for phenomenologists, ethicists, theorists, students, and activists concerned with environmental justice and climate ethics.
