This study explored the practices of teachers, nonformal science educators, community organizers, youth program managers, and other educators facilitating youth participation in local environmental action, as well as the experiences of some of the youth involved. We conducted narrative interviews with 33 educators facilitating youth environmental action in communities throughout the United States and group interviews with 46 youth participating in nine environmental action programs in New York State. Through interpretation of educators' stories and youths' reflections, we discovered strong parallels with theory and empirical research in the youth development literature suggesting environmental action is a valuable context for positive youth development.
