The In Controversy series examines the complex, controversial issues of the day by breaking them into smaller pieces. By studying a specific issue, for example the ethics of embryonic stem cell research, rather than the entire stem cell research debate, students gain a more solid and focused understanding of a topic as a whole. Each book in the series provides a clear, insightful discussion of the issues, integrating facts and a variety of contrasting opinions for a solid, balanced perspective. Personal accounts and direct quotes from academic and professional experts, advocacy groups, politicians, and others enhance the narrative.
