In Wild Souls: Freedom and Flourishing in the Non-Human World (Bloomsbury Publishing, 2021), Emma Marris wrestles with big ethical questions facing the conservation field. Emma takes us through several experiences that informed the book, exposing us to relevant on-the-ground decisions impacting the life or death of animals. When the interests of individual animals conflict with the goals of biodiversity preservation, is it okay to kill? Are any animals truly wild now that humans have directly altered so much of their habitat? How do we balance the rights of introduced species with those already established within an ecosystem? To start engaging these, and other questions, Emma takes us through a needed crash course in ethics, specifically environmental ethics. Much like her previous work, we are exposed to new ways of thinking about old problems. Listening in will not disappoint.
