Sustaining World's Food Production

Caption

In this model of how phosphorus flows through the agricultural system, "knobs" can be turned up or down to create different conservation scenarios. When a knob is turned -- e.g. fraction of animal meat in diet, fraction of food that is wasted, fraction of human waste recycled - the model, which factors in leaks and losses from the food system, loops back to calculate the degree to which phosphate mining could be reduced.
