To prepare today's students to meet growing global environmental challenges, colleges and universities must make environmental literacy a core learning goal for all students, in all disciplines. But what should an environmentally literate citizen know? What teaching and learning strategies are most effective in helping students think critically about human-environment interactions and sustainability, and integrate what they have learned in diverse settings? Educators from the natural and social sciences and the humanities discuss the critical content, skills, and affective qualities essential to environmental literacy. This volume is an invaluable resource for developing integrated, campus-wide programs to prepare students to think critically about, and to work to create, a sustainable society.
