Evoking a concern for intergenerational equity and claiming that the bounty and beauty of Earth have become diminishing prospects, I introduce the Earth Charter as an expression of the hopes of diverse communities around the globe. I argue that the Charter deserves educators' attention as an integrated vision of social justice, peace, and ecological sustainability. I believe the Earth Charter can help transform our conception of what is foundational to include solutions to the deepening anthropogenic ecological crisis. Attention is given to the rationale and methodology for teaching with the Earth Charter. I argue that those in educational studies must deeply engage the problems of our time and that the Earth Charter offers hopeful possibilities for examining and addressing our mutual interconnections.
