This book is based on the fact that slavery still exists in the modern world. It looks at child prostitution, bonded labour, prisoners of war and people trafficking. The investigation is backed up with quotations from experts on the subject, or the victims of slavery themselves. It asks how can slavery persist in the modern world? How can governments across the world tackle this issue? What can we do to support anti-slavery campaigns? This book explores these questions and looks at the effects of slavery across the globe. It is one of a series of books that looks at some of the most important and controversial issues facing the world today. The causes and effects of these subjects are investigated within a global context, while quotations from experts, public figures and people with personal experience of the subjects are featured throughout. In each title, statistics and case studies are used to explore the topic. Kaye Stearman has also written Human Rights: Freedom of Expression.
