Based on nearly two years of ethnographic research with farmworkers in California's Pájaro Valley, in this article I build on Olson's idea of "extreme environments." By merging theories of biopolitics and political ecology, or ecobiopolitics, I explore the naturalization of chemically intensive systems of agricultural production and the health consequences they produce for farmworkers. State and industry regimes of agricultural knowledge and practice are designed to control workers and the environment in strawberry fields. They also produce devastating syndemics and chronicities of disease in farmworker bodies and communities. The relationships between health disparities and farmworkers' lifetimes of exposure to toxic pesticides remain underexplored and poorly understood, perpetuating toxic ignorance about the relationships between pesticides and farmworker health. This enables equating worker well-being with industry well-being. Synergies between ethnographic and environmental health research are needed to challenge toxic ignorance, toxic layering, and the invisible harms they produce in agricultural communities.
Keywords: ecobiopolitics; extreme environments; farmworkers; pesticides; syndemics and chronicities.
