Which work argues that environmental issues are shaped by competing discourses, such as sustainability, ecological modernisation, and green radicalism?

• A. Kenis, A. Post-politics contested: Why multiple voices on climate change do not equal politicisation
• B. Parsons, Laurie. Skeletons, dragons and the 'climate war'
• C. Dryzek, J. S. The Politics of the Earth
• D. Barry, Andrew. The politics of the Anthropocene

Answer: (C)

Environmental politics is shaped less by technical answers alone and more by how problems and solutions are talked into being. Dryzek’s The Politics of the Earth foregrounds this idea, presenting environmental issues as outcomes of competing discourses or frames that people use to describe problems, define legitimacy, and advocate policies. He identifies major ways these issues are framed—such as sustainability, ecological modernization, and green radicalism—and shows how each discourse channels political support, knowledge, and governance choices in different directions. Because it centers on how different voices and their narratives structure the policy debate, this work is the clearest and most influential source for understanding why environmental issues take the shapes they do across contexts.
