Rocks Don't Lie & Dirt: The Erosion of Civilizations
Prof. David Montgomery really likes dirt. In his two lectures, The Rocks Don't Lie: A Geologist Investigates Noah’s Flood and Dirt: The Erosion of Civilizations, he explains how rocks and soil tell us about our world's past, our present and our possibly endangered future, focusing on flood myths in the former lecture, and soil erosion and agriculture in the latter.
