Every morning I wake up to some new set of links to food start-ups that are hoping to do good by doing well. And I wish them more than well, since I’m a big believer in food as the solution to all problems. So I was encouraged to read that vulture capitalists are starting to put their mega-money where their big mouths are. But someone is really going to have to answer why they would invest in the type of companies that are trying to come up with substitutes for nature’s most nearly perfect food. They might as well be attempting to develop a fat-free avocado. The other half of breakfast at least made sense, since even vegans lust for bacon.
