This volume provides a solid, scientific, research-based background to advance understanding of how animals impact humans. It introduces livestock production (including poultry and aquaculture) but also includes coverage of companion and lab animals. In addition, animal behavior and animal perception are covered. It can also function as a reference or recommended reading for a capstone class on ethical and public policy aspects related to animals. This book is likewise an excellent resource for researchers, academics or students newly entering a related field or coming from another discipline and needing foundational information, as well as interested laypersons looking to augment their knowledge on the many impacts of animals in human society.
