How Natural Is "Natural"?

Jonathan Rees's book traces the development of refrigeration from ice harvesting to mechanical systems, showing how cooling technologies transformed food, industry, and urban life. He examines the social, economic, and political forces that drove refrigeration adoption and the resulting shifts in consumption and labor. The book highlights key actors, businesses, and technological advances that made modern cold chains possible. Rees situates refrigeration within broader patterns of industrial modernization and public health concerns. By weaving archival research and narrative history, the book explains refrigeration's profound, often overlooked impact on modern life.

Jonathan Rees examines how societies kept food cool and preserved perishables before mechanical refrigeration, highlighting techniques like ice harvesting, storage, and alternative preservation methods. The book explores the economic, climatic, and technological constraints that shaped pre-refrigeration food systems. Rees uses historical records to show how the demand for cooling influenced trade, labor, and urban development. The narrative connects everyday domestic practices to larger industrial and environmental contexts. It illuminates the continuity and change leading up to the refrigeration revolution.

Alan Levinowitz examines the cultural and historical roots of the belief that 'natural' is inherently good, tracing how this assumption fuels fads, discriminatory laws, and flawed scientific reasoning. He analyzes case studies across food, medicine, and policy to show real-world harms resulting from uncritical naturalism. Levinowitz argues for more nuanced thinking about risk, technology, and public policy, advocating evidence-based decision-making over simplistic natural/unnatural binaries. The book combines scholarly research with accessible examples to illuminate the persistence of naturalist thinking. Ultimately, it calls for reclaiming reason from a sentimental attachment to nature.
