"[The Groundwork Guides] are excellent books, mandatory for school libraries and the increasing body of young people prepared to take ownership of the situations and problems previous generations have left them." -- Globe and Mail Some view the systematic killing, rape and destruction of homes in Darfur as a grave humanitarian crisis. For others, it’s a clear example of the ultimate crime against humanity -- genocide. Who is right? What is genocide? What is the impact on humanity of wiping out entire groups of people? Who are the endangered human beings in today’s world? This thoughtful book helps young readers understand these and other difficult questions. Providing an overview of the history of genocide worldwide, the book explores the paradox that while a person who murders another person can be tried and even executed for the crime, a person who murders hundreds or thousands of people usually goes free. Using case studies the book points out their unique character while at the same time establishing important links between them. Most important, the book answers the question, what can be done to prevent genocide from happening in the future?
