Meat consumption is often a controversial topic, associated with technical, ethical, environmental, political, and health aspects of production and consumption. This book is a broad and interdisciplinary examination and critique of human meat consumption throughout their evolution and around the world. Starting with a chapter on the role of meat in human evolution and its growing influence during the development of agricultural practices, the book examines contemporary production systems, their efficiencies, and impacts. Major global meat consumption trends are described to understand what role its consumption plays in changing modern diets in countries around the world. The heart of the book refers to the consequences of the "mass carnivory" of Western diets, examining the inefficiencies of production and the massive impacts on land, water, and the atmosphere. Health impacts are also covered, both positive and negative. In conclusion, the author looks ahead to his vision of "proper meat consumption," where environmental and health impacts are reduced, animals are treated more humanely, and alternative protein sources contribute to a greater extent. The book "Should We Eat Meat?" is not an ideological essay for or against carnivory, but a careful assessment of the roles of meat in human diets and the environmental and health impacts of its production and consumption. It will interest a broad audience, including professionals and academics in the fields of food production and agriculture, human health and nutrition, environmental science, as well as regulatory and political bodies worldwide.
