From the mid-1980s, meat consumption in Italy and the western world have stabilised and, in the face of a well-established food security, we have witnessed a changed sensitivity for ethical issues, such as animal welfare and environmental impacts of farms. Analysing the sustainability of meat and cured meats means studying in the most objective way possible different topics concerning both the consumer and the livestock production. This volume presents an interdisciplinary study to describe the "5 faces" of meat sustainability: nutrition, environmental impacts and the circular economy applied to farms and industry, food security and animal welfare, the economic aspects of supply chains and the fight against food waste.
