Rockweed: underwater forest or industrial commodity?
Dr. Robin Hadlock Seeley grew up in Maine and has dedicated her life as a scientist to the preservation of coastal ecosystems—in particular a form of seaweed called rockweed. Severine von Tscharner Fleming is the Director of the Greenhorns, a farmer, and activist whose farm is on the Maine coast where rockweed is being harvested by the ton and shipped all over the world. What is the function of rockweed in ecosystems, and what would sustainable harvesting—as opposed to extractive mining—of rockweed look like?

Orchardist Gordon Tooley knows apple trees–and has been cultivating rare and heirloom varieties for three decades. But for him it’s as much about the landscape and lifestyle as about the product. We talk about living slowly, observing closely, and promoting healthy land, water, wildlife, and human communities.
