Description
People have a few other particular needs. We need air for oxygen, as well as fiber for clothing. Upon further consideration it may come as a surprise that much of what we depend on—food, water, fiber, shelter—are all related to a single, often overlooked item. This is soil! Soil (the pedosphere) represents the critical zone of the earth where life (the biosphere), water (the hydrosphere), minerals (the lithosphere), and air (the atmosphere) intersect and interact.
