Manufactured Meat?

The New York Times published this article titled Can People Have Meat and a Planet, Too? about manufacturing meat in a lab as an alternative to raising livestock. Apparently it's far from being an economically viable option, but it could be processed into a burger or nugget form within several years. The proponents of this "franken-meat" argue that it would be more humane and less polluting, but it seems like it would be a lot easier to be more ethical and eco-friendly by simply going veg!
