We're back next week with brand new episodes of the TED Radio Hour featuring our new host, Manoush Zomorodi. While we finish those episodes, Manoush shares a favorite episode of the show from over the years. This episode originally aired on December 7, 2018.

We're told if the economy is growing, and if we keep producing, that's a good thing. But at what cost? This hour, TED speakers explore circular systems that regenerate and re-use what we already have. Guests include economist Kate Raworth, environmental activist Tristram Stuart, landscape architect Kate Orff, entrepreneur David Katz, and graphic designer Jessi Arrington.
