Tina Grotzer and Lynneth Solis (Senior Research Associate, WestEd) recently published a paper in a special issue of the journal Topics in Cognitive Science focused on conceptual foundations of sustainability. The article — titled “Thinking like an Earthling: Children’s Reasoning About Individual and Collective Action Related to Environmental Sustainability” — considers themes that arise from research that inform what is involved in developing a collective, planetary perspective as it relates to engaging in environmental sustainability. While many of the concepts that are inherent to thinking as part of a collective community of Earthlings are challenging, many are also learnable and represent important instructional targets for helping the next generation to understand how to live together in sustainable ways on a small and finite planet.
