Inside the labs crafting slaughter-free meat

The United Nations is urging people to eat less meat, claiming that animal agriculture is a leading cause of greenhouse gases and that eating fewer animals could free up millions of acres of land. Some high-tech laboratories in Tel Aviv are pioneering a new way to make that happen: slaughter-free meat. So-called “clean meat” is created out of cells from farm animal tissues. It’s real steak and real chicken, but no animals are involved. Seth Doane reports. Source
