From a report on The Outline: San Francisco-based startup Memphis Meats announced this week that it had grown chicken in a lab -- chicken strips, to be precise. The strips, which were grown using self-reproducing cells, are technically "meat," but because the cells were not from an animal, the process by which this "meat" was "raised" is much cleaner, resulting in animal food that has the potential to sate both environmental groups as well as animal rights activists and vegetarians. Memphis Meats says it's hoping the product is ready for commercial sale by 2021. The company is part of an ever-increasing horde of Silicon Valley startups trying to solve the complicated problems of the meat industry, which range from cultural ideas about food to industrial and environmental issues to, increasingly, discussions about animal cruelty. [...] About 99 percent of animals raised for slaughter in the U.S. come from factory farms, and about a third of the land mass of the Earth is used in raising livestock. More so than chicken, livestock is incredibly inefficient to raise: It takes about 2,500 gallons of water to produce just a pound of beef.
