This resource provides a wide-ranging survey of the past, present, and future of youth activism in the USA and around the world. The work places a special focus on prominent youth activists, their organizations, and the causes to which they are determined to make change, including civil rights, environmental issues such as climate change, gender and LGBTQ+ rights, and US military actions and financial investments to which they are opposed. How has youth activism changed over the decades? What are the keys to fostering civic engagement among young people? What tools do young people use now to advance political causes important to them? What impact are they having on political and legal struggles over climate change, immigration, and civil rights? This all-in-one resource answers all those questions and more.
