In 2013, Dutch scientists announced that they had produced a lab-grown hamburger. Scientists generated the muscle cells comprising the burger—no animals were killed as part of the process. Many are hopeful that this “cultured meat” is the solution to many societal problems. Earlier this year, author Paul Shapiro and director of The Humane Society released a book called Clean Meat: How Growing Meat Without Animals will Revolutionize Dinner and The World. The book provides a history of the development of meat produced in labs and discusses the moral benefits of a future that includes meat produced in this way.
