Students use their ecological knowledge of soil processes, energy, water systems, and human interactions to compare the environmental impact of food production. Each group of 3-4 students develop life cycle analyses (LCA) for a single crop grown under different scenarios. As individuals, students are responsible for developing two LCA for that crop, and then together in their groups, they compile those LCA to assess which combination of growing method and location is most green if you are purchasing this product at the location of our college. In their joint assessments, students justify their answer based on findings from their LCA. Through this activity, students recognize that there is not one simple answer (e.g., always buy organic) but rather, which methods are most ecologically sustainable are often dependent on the crop, the local conditions, and the impacts of both humans and the environment.
