Be sure to watch this in HD. There are lots of small details. Even better, also watch it in Full Screen or on YouTube in LargePlayer.
The WorldChange model was created by adding a change resistance subsystem to the World3 model of Limits to Growth. The video gives an overview of how the subsystem works, what the root causes and high leverage points are, and the WorldChange model conclusions. The conclusions are expressed in terms of simulation scenarios.
