Mathis Wackernagle on Making Sustainability Real with the Ecological Footprint

Are we running out of planet? Do economies self-correct or self-destruct when operating as if resources are limitless? How do we meassure our footprint and what do we do once we know this? In this 2006 Sydney Ideas lecture Mathis Wackernagel, co-creator of the Ecological Footprint concept explored these questions and demonstrated how the meassuring tools can help in better management of our ecological assets.
