Environmental History of the United States

In this episode, we dive into the Environmental History of the United States, exploring how Americans have shaped—and been shaped by—the natural world from pre-Columbian Indigenous stewardship to the rise of modern environmental activism. We examine the dramatic transformation of the American landscape through colonization, westward expansion, industrialization, and resource extraction, highlighting the environmental consequences of deforestation, pollution, and rapid economic growth. The discussion also covers the emergence of the conservation movement during the Progressive Era, the influence of leaders like Theodore Roosevelt, and the rise of organizations such as the Sierra Club that pushed environmental protection into national politics. Finally, we explore the changing energy economy—from wood and coal to nuclear and renewable power—and the growing environmental justice movement, which exposed how pollution and ecological harm disproportionately affect marginalized communities and Indigenous nations across the country.
