Greenhouse: Saying goodbye to Styrofoam


Tony Dokoupil talks to Ruth DeFries about how much time humans have left in this planet. Later, he says goodbye to Styrofoam before a ban goes into effect in New York City. Dokopuil then explains why farming crickets makes sense, and sits down with an executive for Novelis to take a look at the “Evercan” – a can made out of 90% recycled aluminum.
