Welcome to the future, where food no longer comes from nature. In a story that sounds more relevant to a sci-fi novel than a cookbook, scientists have been working hard on creating test tube meat! That's right, no animals were harmed, or even used in the creation of this steak. The arguments for it are that it will prevent animal cruelty and reduce the environmental load from factory farms. While it's true that  factory cows do require fields of wheat, corn, and soy; their grass-fed cousins do not. Supporting ethical and sustainable farms may be a better solution for those that don't wish their food to be created in a lab.
