TENANTS HARBOR — Jackson Memorial Library, 71 Main St., hosts an author talk with Margot Kelley Thursday, Aug. 11, at 5 p.m. Kelley will be discussing her book “Foodtopia.”

Margot Anne Kelley

“Foodtopia” tells the story of five back-to-the-land movements, from 1840 to present day, when large numbers of utopian-minded people in the United States established small-scale farming as an alternative to mainstream agriculture. It is about American utopians, and the stories range from that of Henry David Thoreau moving to Walden Pond in the 1840s to those of disenchanted millennials leaving the city and learning to farm in the 2010s.

Several members of the St. George community are featured in the section on back-to-the-landers from the 1970s. As the book’s title suggests, all of the people included had strong beliefs about the role food played in living out their utopian ideals.
