The U.S. Department of Agriculture has approved the sale of lab-grown meat for the first time. The USDA’s approval on Wednesday came after the Food and Drug Administration in March cleared “cultured chicken cell material” made by the company GOOD Meat as safe for use as human food. Proponents say lab-grown meat provides a humane option for people who wish to consume meat but don’t want to contribute to animal suffering, greenhouse gas emissions and other environmental damage caused by factory farming.
