Dennis Meadows
"Dennis Meadows, professor emeritus of systems policy at the University of New Hampshire who headed the original M.I.T. team and revisited World3 in 1994 and 2004."
"Meadows holds that collapse is now all but inevitable, but that its actual form will be too complex for any model to predict. "Collapse will not be driven by a single, identifiable cause simultaneously acting in all countries," he observes. "It will come through a self-reinforcing complex of issues"—including climate change, resource constraints and socioeconomic inequality."
