Nancy Langston is distinguished professor of environmental history at Michigan Technological University. Langston was trained both as an environmental historian and as an ecologist. In addition to numerous peer-reviewed journal articles and popular essays, she is the author of Forest Dreams, Forest Nightmares: The Paradox of Old Growth in the Inland West; Where Land and Water Meet: A Western Landscape Transformed; Toxic Bodies: Hormone Disruptors and the Legacy of DES; and Sustaining Lake Superior: An Extraordinary Lake in a Changing World. Langston is a former president of the American Society for Environmental History and former editor-in-chief of the field's flagship journal, Environmental History.

"Langston focuses on three ghost species in the Great Lakes watershed-woodland caribou, common loons, and lake sturgeon. Their traces are still present in DNA, small fragmented populations, or in lone individuals. We can still restore them, if we make the hard choices necessary for them to survive"--
