How to Collect City Trash.

Americans generate more trash than anyone else on the planet: more than 7 pounds per person each day. Journalist Edward Humes explores how that happened in his new book Garbology: Our Dirty Love Affair with Trash.

The man behind Nemo and Wall-E has warmed hearts with his unlikely heroes — a clownfish? A sentient trash compactor? He tells Terry Gross about finding inspiration in unlikely places, and in everyday objects.

Garbage expert Benjamin Miller discusses the history of rubbish in New York. He’s the former director of policy planning for the New York City Department of Sanitation. He’s just written a book on the subject, entitled “Fat of the Land: Garbage in New York – The Last 200 Years.” (Four Walls Eight Windows) Miller says that the dumping of garbage has literally shaped New York City as it took over surrounding islands and bulked up Brooklyn, Queens and Manhattan.
