This chapter explains the importance of telling the story of “advancing urbanization”—both the global acceleration of urbanization and the promise offered by urbanization—for urban environmental education. It argues that cities—their design and how we live in them—will be key in our struggle for sustainability, indeed our future. As cities grow, as they are newly created, and as more and more people choose or require them as places to live, our decisions about urban design and city building will determine the outcomes of long-term challenges related to resilience, sustainability, livability, and justice. Rather than being the essential cause of the global environmental dangers we face, cities will be key to success in overcoming these dangers. The chapter examines the role of environmental education in fostering public engagement through clarifying and transmitting the challenges, values, actions, and methods for achieving sustainable, resilient, livable, and just cities.
