Ecological economics has a long tradition of disputing the mainstream economic view that people’s concern for the environment scales with income, and that it’s a luxury good. The main counterargument is the widespread evidence on environmental justice conflicts, encapsulated by what Joan Martinez-Alier called the ‘environmentalism of the poor’. Today, we focus on the role and importance of people working on the front lines of environmental degradation – biosphere defenders. Our guest today is Dr Claudia Ituarte-Lima. Hosted by Sophus zu Ermgassen. Edited by Aidan Knox.
