Listening to New York City sanitation workers - and working side-by-side with them - NYU professor Robin Nagle uncovered a wealth of knowledge about the job and the people who keep the city clean.
Nagle also talks about our relationship with trash - and why we might want to respect, maybe even love, what we leave behind. This is an anthropological study well worth learning from.
