Abstract: From 10,000 meters up, the impact of humans on the Earth is clear. Cities spanning kilometers are connected by roadways stretching to the horizon. Crowding the spaces in between are fields that supply food and industrial feedstock to satisfy a variety of human hungers. These fields feed humanity. Through stewardship we maintain their productivity and thus sustain societies that extend around the globe; if these fields fall into ill health, or if we push them into sickness, we risk the fate of those same societies.
