The local-eating fad isn't just for hippies, writes Felix Salmon -- it's actually a powerful example of the direction in which we should all be heading. Mass agriculture is cheap, Salmon notes, but it's also inherently wasteful and vulnerable to disease and natural disaster. "Local farmers growing local food can create a much more sustainable life for themselves and those around them than Western agribusinesses can," Salmon argues. "At the very least, locavores should be an important part of the mix."
