Chris and Xand continue their conversation about nature with Baroness Kathy Willis, Professor of Biodiversity at Oxford University.

They look a little deeper into the relationship between nature and our health and wellbeing. They also discuss Kathy's thoughts on how society interacts with nature. These insights go beyond the science to explore the bigger picture of our relationship with the natural world. Plus, they discuss what we can be doing to help the natural world in return for helping us.

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
