Sustainability is a core 21st-century movement that stresses keeping interrelationships among the environment, human cultures, and economic systems healthy now--and for future generations--across local, regional, national, and global levels. The ideal sustainable community is able to maintain this balance among the social, environmental, and economic pillars locally, without using an abundance of outside resources or disrupting the local ecosystem. Using children's literature that features unique stories of children and families around the globe, classroom teachers can begin discussions about sustainability in their classrooms. This article highlights several works of children's literature that might be appropriate springboards for engaging young learners in such discussions, and then focuses on one particularly engaging children's book in order to illustrate more specifically how educators might present a concrete introduction to these concepts.
