Call off the search for the new kale: we’ve found it, and it’s called kelp! In this episode of Gastropod, we explore the science behind the new wave of seaweed farms springing up off the New England coast, and discover seaweed’s starring role in the peopling of the Americas.

The story of seaweed will take us from a medicine hut in southern Chile to a high-tech seaweed nursery in Stamford, Connecticut, and from biofuels to beer, as we discover the surprising history and bright future of marine vegetables. Along the way, we uncover the role kelp can play in supporting U.S. fishermen, cleaning up coastal waters, and even helping make salmon farms more sustainable.
