This important new book illustrates how to create the social breakthroughs needed to solve urgent global threats such as poverty, disease, and hunger. It then turns to three alternative, but complementary, paths to social breakthrough: social protecting, social exploring, and social advocacy, providing a detailed map of the journey from initial commitment to a world of justice and opportunity Author Paul Light believes we should be less concerned about the tools of agitation (social entrepreneurship, social protecting, social exploring, and social advocacy) and more concerned about the disruption and replacement of the status quo. Timely in its urgency, this book describes the revolutionary social impact cycle, which provides a new approach for framing the debate about urgent threats.
