The contributors to Reactivating Elements examine chemicals as they mix with soil, air, water, and fire to shape Earth's troubled ecologies today.They invoke the elements with all their ambivalences as chemical categories, material substances, social forms, forces and energies, cosmological entities, and epistemic objects.Engaging with the nonlinear historical significance of elemental thought across fields-chemistry, the biosciences, engineering, physics, science and technology studies, the environmental humanities, ecocriticism, and cultural studies-the contributors examine the relationship between chemistry and ecology, probe the logics that render wind as energy, excavate affective histories of ubiquitous substances such as plastics and radioactive elements, and chart the damage wrought by petrochemical industrialization.Throughout, the volume illuminates how elements become entangled with power and control, coloniality, racism, and extractive productivism while exploring alternative paths to environmental destruction.In so doing, it rethinks the relationship between the elements and the elemental, human and more-than-human worlds, today’s damaged ecosystems and other ecologies to come.
