But in recent years, environmentalists have branded corn as an icon of unsustainable agriculture. It requires large amounts of fertilizer and pesticides, both of which require large amounts of fossil fuel to manufacture. Most of the resulting corn is fed to livestock who didn't evolve to subsist entirely on corn. In cattle, eating corn increases flatulence emissions of methane - a potent greenhouse gas - and creates an intestinal environment rich in e. coli, a common cause of food poisoning.
