A hybrid of memoir and political manifesto, Suicide was written during the author’s imprisonment after the high-profile Whole Truth Five trial linked to Just Stop Oil. Hallam, one the founders of Extinction Rebellion, presents the defence he was banned from making in court, exposing the legal system’s failure to confront the climate crisis. Drawing on climate science, legal theory, and personal experience, he argues that the institutions meant to protect society are collapsing. In both his critique of modern thinking and his forceful call for direct action, he urges readers to rethink justice, duty, and truth in an age of ecological emergency.
