Winston Churchill once predicted that it would be possible to grow chicken breasts and wings more efficiently without having to keep an actual chicken. And in fact scientists have since figured out how to grow tiny nuggets of lab meat and say it will one day be possible to produce steaks in vats, sans any livestock.
Pork chops or burgers cultivated in labs could eliminate contamination problems that regularly generate headlines these days, as well as address environmental concerns that come with industrial livestock farms.
However, such research opens up strange and perhaps even disturbing possibilities once considered only the realm of science fiction. After all, who knows what kind of meat people might want to grow to eat?
