Young people's lives are increasingly shaped by digital media, yet public and academic debates about youth, social media and well-being are often dominated by fear-based narratives that frame online spaces as inherently harmful. Against a backdrop of rising concerns about youth mental health and widespread anxieties about social media use, this book offers a critical and timely intervention into how we understand young people's political and civic engagement in the digital age. Drawing on in-depth interviews with youth activists involved in the international climate change movement and the American gun control movement, alongside analysis of their social media practices, the book challenges binary distinctions between online and real-world activism. Rather than treating digital participation as superficial or ineffective, it foregrounds young people's own perspectives on activism, demonstrating how digital platforms function as meaningful spaces for connection, organizing and political expression.

Situated at the intersection of youth studies, sociology, media studies and political engagement, the book builds on and extends existing literature on digital activism by centring youth voices and lived experience. It offers a counter-narrative to the persistent "slacktivism" critique, arguing that such framings not only misunderstand contemporary activism but risk delegitimizing young people's contributions to civic life. Written in an accessible style while grounded in rigorous social research, this book will be of interest to scholars, post-secondary students and practitioners working in education, youth work, child and youth care, social services and community organizing. It is suitable for classroom adoption, scholarly reference and professional reflection, and provides valuable insights for anyone seeking to better understand how young people are reshaping political participation in a digitally networked world.
