Briefly, humanity has overshot the limits of what is physically and biologically sustainable. That overshoot WILL lead to the collapse of the planetary environment’s ability to support not only our species but much of the rest of the biosphere if we do not act rapidly and effectively to reduce our footprint. These conclusions provide reasons for both optimism and alarm: optimism because humanity has demonstrated its capacity to act appropriately in one specific instance; and alarm because thirty years have been largely wasted since the consequences of our failing to act were detailed. There is still time but the need to act quickly and effectively is urgent. The authors demonstrate that the most critical areas needing immediate attention are: population; wasteful, inefficient growth; and pollution. They show how attention to all three simultaneously can result in returning the human footprint on the environment to manageable, sustainable size, while sharply reducing the disparity between human well-being and fostering a generous quality-of-life worldwide. Absent this, the prospects are grim indeed.
