From often amusing perceptions people have had through the ages about the world and the universe to the changing map of today, Davis shows how geography is really a great crossroad of many fields: biology, meteorology, astronomy, history, economics, and even politics. In this lively, entertaining, and endlessly fascinating presentation, you'll hear about the personalities that helped shape the world and learn the answers to questions that have vexed most of us since grade school. Along the way, Davis offers an affectionate ode to the earth: a celebration of the earth, a searching investigation of the destruction of our habitat, and a practical guide to saving our home planet.
