Civilopedia: The concept of "Sythetic Foods" stemmed from a great deal of science fiction where the average person is forced to subsist on vegetarian diets due to the overcrowding of earth. However, the true effect of "Soylent" caught on in the 1973 film "Soylent Green" where society is forced to first subsist on soy and lentil crackers before accepting a form of cannibalism via Soylent Green. Despite the claim that humanity would be forced to subsist on such foods in the future. The abundance and choice of food meant that in a way, humanity is unlikely to develop a culture of food made from synthetic chemicals. Despite that, many look at this as a means of substance in long trips out to space, that a reliable means of food can be found. The Cornucopia Vat is a reflection of the production of soylent type foods

Civilopedia: In the future, many believe that there will be less arable land for protein rich animals such as cows or pigs and deer. One popular theory was the development of In Vitro Meat is animal flesh that has never been part of a complete, living animal. Several current research projects are growing in vitro meat experimentally, although no meat has yet been produced for public consumption. The advent of advanced technology in culturing agents changed all that and the Meat Vat was born. Being able to mass produce quality animal meat that is almost indistinguishable from normal meat. The fact that the meat is also not from animals but from a vat meant for the first time in the turn of the century many religious or ethic groups can potentially enjoy meat at last.
