December 20, 2016: Hour 1

In hour one of Here & Now's Dec. 20, 2016 full broadcast, we hear host Meghna Chakrabarti's conversation with Spanx founder Sara Blakely about how her company has grown, and her plans for the future. And amid polar bears showing up more frequently in villages along Alaska's North Slope, we speak with a wildlife biologist about how melting sea ice is driving the animals to find food outside their normal habitat. You can read and hear more at hereandnow.org, follow us on Twitter and join the conversation on Facebook and Tumblr.
