You may have heard that Americans throw away more than any other nation, but any idea of just how much? Each of us is on track to toss 102 tons of garbage in our lifetime. More than 7 pounds a day, and twice what we chucked out in 1960. Pulitzer Prize winner Edward Humes believes we are living in a state of garbage denial. His new book is called Garbology: Our Dirty Love Affair with Trash. In it, he looks at the science, politics, and economics of waste.
