This unique book is divided into two sections. The first section highlights specific international youth activists, their biographies, work, and accomplishments. The second section is a collection of work by youth, who address their own activism, goals, identities, and needs. Commentaries by teachers, community workers, and facilitators compliment the entries, creating a unique, intergenerational and multi-faceted volume. The book will serve to fill a gap in teacher education, highlighting and listening to youth, themselves, who, the editor, contends, should be intimately involved in their own education and futures. A new model for teacher education, this book allows teachers to understand that youth must have, and demand, a voice in the determination of their lives and futures. Previous work with youth tends to “deal with them” as a problem to be solved, a group to be managed. This book insists that youth are viable citizens and create a voice which is heard internationally. Activists under 30 is the first book of its kind, to be addressed to youth, teachers, parents, and activists. It reminds us that youth are our most valuable resource, and insists we incorporate them, invite them, and listen to them.
