Land ethics are the ways that humanity justifies their usage of the land. Today this topic is more important than ever as we balance our needs, such as food, water, and energy, with the systems of the natural world. The activity described in this article introduces students to the concept of land ethics using historical case studies of five common categories of ethics. The activity ends with a symposium examining a real-life example: Grand Staircase-Escalante National Monument (GSENM) in southern Utah, and the potential future use of this land. Engaging students in argumentation about this example allows them to see multiple sides of this complex issue.
