The major global initiative that incorporates livestock in agroecology, partly under the umbrella of One Health, is changing the perception of livestock in ethical and sustainable food systems. One Health has the core principles of healthy animals, healthy ecosystems, and healthy people. In terms of health, natural meat is a nutrient-dense, nutritious food that contains all nine essential amino acids, the six conditionally essential amino acids, plus key minerals and vitamins. Notwithstanding the changing role of livestock in landscapes, negative perceptions created the opportunity for the emergence of the cultured (laboratory-grown) muscle cell (CMC) industry. The latter makes claims of minimal impact on the environment and a significant reduction in livestock in food systems, which is promoted as animal welfare. The production and composition of CMC food is protected under intellectual property law and proprietary licenses.
