Our modern civilization is in trouble. We have created a bubble economy, one whose output is artificially inflated by over-consuming the earth's natural capital. Nowhere is the bubble economy more evident than in the food sector where the world grain harvest has been inflated by over-pumping aquifers, a practice that virtually guarantees a future drop in production when aquifers are depleted. Plan B is a way of sustaining economic progress worldwide, an alternative to continuing environmental deterioration and eventual economic decline.
