The importance of gathered botanical and ecological knowledge to our survival as human beings in a changing landscape is explored. Suzanne Lang talks with evolutionary biologist and science writer Erin Zimmerman, whose book is Unrooted: Botany, Motherhood, and the Fight to Save an Old Science, a memoir of botany and natural history seen through the lens of her own career, the barriers she faced, and the work she’s done. Suzanne also talks with Manjula Martin on her book, The Last Fire Season; A Personal and Pyronatural History, which weaves her personal journey through health issues with her exploration of fire, place, gardening, indigenous knowledge, and living in a body and a landscape that sometimes confound.
