The average American family of four wastes between $1,350 and $2,275 a year in food. Much of that ends up in the kitchen trash can: uneaten leftovers, milk past the expiration date and vegetables that go bad.
In the U.S., all that waste adds up to 90 billion pounds of food a year, and the planet is paying a staggeringly high price for it.
"It's not something many people think about, but it takes a huge amount of resources to get food to our plates," says Dana Gunders, a scientist with the Natural Resources Defense Council.
