Andrew Faust, a permaculture designer with the Center for Bioregional Living, lays out his case that ecological understanding is inseparable from a scientific picture of deep time. Drawing on twenty years of teaching and eight years living off the grid, he traces the universe back roughly 14.5 billion years, then narrows down through the Milky Way's spiral arm to a planet he describes as a self-regulating biological entity. He points out that plate tectonics was not accepted science until the 1970s and that ice ages were not agreed upon until the 1930s, using both as evidence for how recently humans have understood the ground they stand on. Five hundred million years ago, he notes, the continents sat in entirely different positions, part of a planet still actively reshaping itself. Faust's argument has a pointed edge: there is no guiding force looking after humanity, so figuring out how to live within Earth's systems is a task left entirely to us. The talk stays a single unbroken narration, no interviews or footage, just Faust building his argument point by point.
