New Natures broadens the dialogue between the disciplines of science and technology studies (STS) and environmental history in hopes of deepening and even transforming understandings of human-nature interactions. The volume presents historical studies that engage with key STS theories, offering models for how these theories can help crystallize central lessons from empirical histories, facilitate comparative analysis, and provide a language for complicated historical phenomena. Overall, the collection exemplifies the fruitfulness of cross-disciplinary thinking.
