In Episode 316, we emphasize the importance of water. In Oil in Eden, produced by Jonathan Horowitz, we look at ways that oil wastewater is being treated to supply water for some farms in California. In The Kelp Initiative, produced by Colin Taylor, we follow scientists who are exploring how a common ocean plant might be useful for combating climate change. And in Breathtaking, produced by Savannah Welch, we meet competitive freedivers who push themselves to their limits with each dive down.
