Nicholas Kristof has a piece in the NYTimes describing the progress being made in developing edible fake meat. It sounds promising. I've no problems with the effort.
I do wonder though how the food movement and the environmentalists will react if fake meat becomes a reality. A fake steak would be good for global warming, given the methane production of cattle. But it seems to me that fake meat should raise all the concerns which the food movement voices in connection with genetically modified organisms.
