Dana (Donella) Meadows Lecture: Sustainable Systems

Two years before her death, Meadows delivers a complete course in systems thinking in a single lecture at the University of Michigan. She walks through stocks, flows, feedback loops, and delays — then shows why growth in a finite system always meets its limits, and why the point of a model is not prediction but understanding. The lecture is the closest thing on film to the argument of Thinking in Systems, delivered with the plainspoken patience of someone who spent three decades teaching people to see the structures behind events.
