Steven Stoll studies the ways that people think about resources, capital, and how the economy of exchange functions within the larger economy of Earth. He is an environmental historian, but his work is related to geography, social ecology, and the political theory of the seventeenth, eighteenth, and nineteenth centuries.

He is the author of U.S. Environmentalism Since 1945 and The Great Delusion: A Mad Inventor, Death in the Tropics, and the Utopian Origins of Economic Growth. Stoll is a regular contributor to Harper's Magazine and teaches history at Fordham University.
