This book offers a distinctive, balanced coverage of environmental issues, policies and action. This revised fourth edition has been expanded and fully updated to explore contemporary developments and issues within global environmental sociology. Environmental Sociology reconciles Hannigan's widely cited model of the social construction of environmental problems and controversies, which states that incipient environmental issues must be identified, researched, promoted and persuasively argued in the form of "claims", with an environmental justice perspective that stresses inequality and threats to local communities. The updated fourth edition also discusses new direct action protest groups, such as Extinction Rebellion, who have reframed the discourse around the "climate emergency" using apocalyptic language and imagery. Environmental Sociology also signposts exciting new directions for future research. The fourth edition re-interrogates the classical roots of environmental theory with a focus of the work of Alexander von Humboldt. Hannigan also asserts the need for environmental sociologists to turn their attention to "The Forgotten Ocean", arguing that the discipline should incorporate cutting-edge concepts such as marine justice, striated space and volumetrics. Environmental Sociology is a key text for students and researchers in environmental studies, political ecology, social geography and environmental sociology.
