Your co-hosts talk clonal trees and dispense important advice about relationships, breakups, and having "the conversation" with your children on this week's podcast. Then (17:16) we talk to Brown University's Bathsheba Demuth (http://www.brdemuth.com) about her new book Floating Coast (https://wwnorton.com/books/9780393635164) a beautifully conceived and written environmental history of the Bering Strait from the 18ththrough the 20thcenturies. We start with how American and Soviet modernist projects differentially impacted Beringia during the 20thcentury and why the oceanic productivity of the Arctic attuned her to the energy transformations that then became a powerful red thread throughout the book. We turn from there to the temporality of whales, baleen as infrastructure and path dependency, Soviet vs. American conceptualizations of progress, the place of indigenous memories and knowledge in her historical methodology, and much much more.
