The U.S. wastes a stunning amount of food -- 40 percent of what we produce, according to Jonathan Bloom, author of American Wasteland. That’s way above the already-staggering global average of one third. That means that 40 percent of the energy, water, and fuel we put into farming goes straight into the trash. All in all, Bloom says, “2 percent of all U.S. energy goes to food we’re throwing away.”
