This week, we are going to be exploring the relationship between presidents, the bully pulpit, and environmental protection. When did presidents start thinking about federal use of land? When did that consideration change from an economic one based on maximizing profit and agricultural production for white settlers to something else?

We are going to tackle these questions and more on today's episode. First, we spoke with Dr. Mark David Spence, the author of Dispossessing the Wilderness: Indian Removal and the Making of National Parks, about the early history of presidents and land as a national resource. We talked about the role of national parks in the late 19th century and the complicated relationship between national parks and native peoples.

Next, we spoke with Dr. Megan Kate Nelson, the author of Saving Yellowstone: Exploration and Preservation in Reconstruction America. Nelson gave us a history of the first national park in the world, told us about the outsized impact of Theodore Roosevelt in the national park system, and discussed executive action on national parks today.

Finally, we spoke with Dr. Brooks Flippen, author of Nixon and the Environment, about Richard Nixon, environmental protection, and the creation of Earth Day. Brooks shares the really interesting political motivations behind Nixon's climate actions. You might be surprised to learn that climate change was once a bipartisan issue!
