All season, we’ve been unpacking the controversial ways we’re messing with nature to save the planet. In this episode, we explore the wildest intervention to date: de-extinction. We take a tour of Colossal Labs, the $10 billion Dallas startup betting it can reverse-engineer extinction itself, to see how they plan to turn pigeons into dodos and Asian elephants into woolly mammoths.

After the tour, host Amy Scott chats with Pulitzer Prize-winning environmental journalist Elizabeth Kolbert to find out.
