Dave Montgomery - Dirt: The Erosion of Civilizations

Webcast sponsored by the Irving K. Barber Learning Centre. Author David Montgomery has discovered that the three-foot-deep skin of our planet is slowly being eroded away, with potentially devastating results. In this engaging lecture, Montgomery draws from his book 'Dirt: The Erosion of Civilizations' to trace the role of soil use and abuse in the history of societies, and discuss how the rise of organic and no-till farming bring hope for a new agricultural revolution.
