Almost one-thirds of all the food produced in the world is never eaten. At 2.8 trillion pounds, that is sufficient food to take care of three billion individuals. In the United States, the waste is much more horrifying: More than 30% of our food, esteemed at $162 billion yearly, isn't eaten. An American family of four trashes a $1,484 worth of consumable food a year.
Growing food uses resources: 20 percent of our land, 32 percent of the energy we produce and 70 percent of the water we withdraw from lakes, rivers and underground. When we waste food, it wastes the water and energy it took to produce it. Hence, squandering food also squanders the vast quantities of fuel, agricultural chemicals, water, land, and labor needed to produce it.
