Italian researcher Isabella Dalla Ragione has a most unusual job. An “arboreal archaeologist,” Dalla Ragione scours Renaissance paintings and medieval archives, discovering endangered fruits that might be revived. Her life’s work offers a possible solution to the problem of monocrops.  Year after year, agricultural giants cultivate the same varieties of the same fruits and vegetables, while many other varieties have fallen to the wayside. Monocrops contribute to climate change and are highly susceptible to its consequences, jeopardizing our food supply. In this episode, Isabella and Smithsonian contributing writer Mark Schapiro discuss the importance and challenges of protecting biodiversity and agriculture in the midst of a changing climate — and why it matters. Read Mark's story for Smithsonian magazine here.
