Producing meat through cell culture, currently known as cultured -or clean- meat is being developed as an alternative to livestock produced meat. Starting with the authoritative report by the FAO in 2006, it is increasingly clear that livestock meat production, beef in particular, is unsustainable (FAO, 2006). The 2011 update of that report shows that it is physically impossible to match the 70% rise in demand for meat by 2050 given the constraints of available resources (FAO, 2011). Accepting theseconstraints and production limits while demand for meat rises, will make meat an increasingly scarce and expensive commodity. Most likely, meat producers will try to serve the demand by increasing production, leading to higher volumes of feed production. Since in factory farming, feed consists mainly of corn and soy, increasing meat production will lead to reduced availability of these staple foods for direct human consumption and thus pose a threat to global food security.
