Text focuses on questions about the production and spread of knowledge, and the role science plays in society. Thom and Mah introduce the term “post-truths” that is defined by the Oxford Dictionary as “denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.” Which factors into how the intersection of science, politics, and values around the world determine a population’s attitude towards environmental justice. They argue for the importance of “science, knowledge, and data that are produced by and for ordinary people living in environmental risks and hazards” (Thom and Mah 2022). In doing so, they recognize data isn't sufficient to solve environmental injustice, especially since issues of environmental pollution are so deeply intertwined with structures that perpetuate social inequalities. Instead, they suggest an interdisciplinary approach that integrates “legacies of environmental justice movement, participatory citizen science,” and “experts” to come up with holistic questions on how to overcome environmental inequality and advance the environmental justice movement amid challenges on the salience of environmental expertise.
Thom and Mah use four case studies of community-based participatory environmental health and justice research to show the importance of including citizens in scientific research. Citizen science refers to public engagement with science, from data sensing and crowdsourcing to design, collection, analysis of research. Although citizen science is not the only answer - with Catree (2016) pointing out that citizen-led processes have become a “lucrative business,” which creates a conflict of interest - this book redefines the meaning of “justice” within the environmental justice movement and explores “role and interpretation of citizenship within citizen science research (Thom and Mah 2022). They recognize there’s tension in balancing a community’s subjective experience and contextual knowledge with rigorous, scientifically appropriate research.
To tackle environmental injustice in a post-truth era, Thom and Mah (2022) argue there needs to be political change. An interdisciplinary approach is used to study local and global environmental justice challenges with a range of “qualitative and quantitative social science methods, including community-based participatory research (CBPR), epidemiology, ethnography, visual methods, and other innovative methods of participatory environmental justice and citizen science research” (Thom and Mah 2022).
