In The Size of the Risk, Leisl Carr Childers shows how different constituencies worked to fill the presumed "empty space" of the Great Basin with a variety of land-use regimes that overlapped, conflicted, and ultimately harmed the environment and the people who depended on the region for their livelihoods. She looks at the conflicts that arose from the intersection of an ever-increasing number of activities, such as nuclear testing and wild horse preservation, and how Great Basin residents have navigated these conflicts.
