We’ve got a great guest episode for you today, coming courtesy of our friends over at the podcast Cited.

They’ve got a new series out called “Green Dreams” — covering stories of radical environmentalist thought leaders, and the ripples they’ve left on the present day. We wanted to share with you the very first episode from this series, called “The Green Cosmos”, covering Gerard O’Neil’s 1970s vision for humanity’s passage to the stars.

Find the rest of Green Dreams and much more from Cited wherever you're listening.
