This resource considers soil as a system. When plants naturally decay, their nutrients return to the soil and keep it healthy. This video from Nourish, featuring author Michael Pollan, explains how soil health can decrease over time unless harvested plants are composted and returned to the soil. The support materials cover systems litearcy concepts of causal loops and stocks and flows. This resource is part of the Systems Literacy Collection.
