Ryan M. Yonk joins us this week for a discussion about how we think about ecology and the environment. We talk about various environmental regulations including the Clean Air Act, the National Environmental Policy Act, and the Endangered Species Act.What counts as a “natural balance” in ecology? Is the ideal environment one with no human impact at all? What is “political entrepreneurship” and how do environmentalists use it to push for their policy goals?Show Notes and Further ReadingYonk is coauthor, along with Kenneth J. Sim and Randy T. Simmons, of Nature Unbound: Democracy vs. the Environment (2016).Trevor mentions this Free Thoughts episode, in which Van Doren suggests that the US government gift the Arctic National Wildlife Refuge to the Sierra Club, effectively assigning them responsibility for any economic benefits that would come from drilling for oil there.
