Whether we live in cities or suburbs, whether we're aware of it or not, people have deep-seated connections to nature. Our ancestors lived with a real and present sense of the wild animals and plants around them. In his book, Our Wild Calling, journalist Richard Louv challenges us to understand and appreciate our link to animals, domestic and wild. Dr. Cassandra Quave, an Emory Ethnobotanist, leads an international team searching for plant-based medicines to replace failing antibiotics. Krista Schlyer, an international conservation photographer, explores animals that have a need to roam across our southern border.
