When it comes to any current scientific debate, there are more than two sides to every story. Controversies in Science and Technology, Volume 4 analyzes controversial topics in science and technology-infrastructure, ecosystem management, food security, and plastics and health-from multiple points of view. The editors have compiled thought-provoking essays from a variety of experts from academia and beyond, creating a volume that addresses many of the issues surrounding these scientific debates. Part I of the volume discusses infrastructure, and the real meaning behind the term in today's society. Essays address the central issues that motivate current discussion about infrastructure, including writing on the vulnerability to disasters. Part II, titled "Food Policy," will focus on the challenges of feeding an ever-growing world and the costs of not doing so. Part III features essays on chemicals and environmental health, and works to define "safety" as it relates to today's scientific community. The book's final section examines ecosystem management. In the end, Kleinman, Cloud-Hansen, and Handelsman provide a multifaceted volume that will be appropriate for anyone hoping to understand arguments surrounding several of today's most important scientific controversies
