The education for sustainability movement is as diverse as it is vibrant. Some school communities focus on bringing sustainable practices to their teaching and learning or the relationships they cultivate within the larger community. Others focus on their food systems or their buildings and campuses. Over the course of nearly twenty years, we have developed principles, practices, and resources based on our work with thousands of educators in this hopeful and vital movement. We have also documented the stories of successful practitioners along the way. In this section, we present some highlights.
