The author has been teaching a graduate course entitled Envisioning a Sustainable Society since 1996 that seeks to explore the possible dimensions of a transformation of people's way of life and their beliefs about humanity's relationship with the planet. Designed for future teachers, educational leaders, and counselors, the course focuses on the implications of contemporary environmental and social crises for people in schools and counseling centers and the role they might play in addressing these issues. The course considers technological changes that support the creation of a more earth-friendly and just society, but focuses primarily on cultural and attitudinal shifts needed to reduce humanity's footprint on the planet and to distribute its limited resources more equitably. This article shares the author's experience in designing this course about sustainability and describes how he taught the course.
