They discuss the work of Ellen Churchill Semple, a pioneering geographer whose insights into how geography shapes culture and civilization are often overlooked. The conversation explores various examples, including the influence of geography on European cultures, the impact of technology on human geography, and the significance of land surveying in shaping the American landscape. Jenny also shares a case study on the Anasazi civilization in the Southwest, examining how geography influenced their way of life and eventual collapse. The episode concludes with reflections on the legacy of Semple and the importance of understanding geography in today's world.
