This looks to be an interesting read from Pulitzer Prize-winning author Miriam Horn: Rancher, Farmer, Fisherman: Conservation Heroes of the American Heartland. The book was also recently made into a documentary, narrated by Tom Brokaw. From the book description:
“Many of the men and women doing today’s most consequential environmental work—restoring America’s grasslands, wildlife, soil, rivers, wetlands, and oceans—would not call themselves environmentalists; they would be too uneasy with the connotations of that word. What drives them is their deep love of the land: the iconic terrain where explorers and cowboys, pioneers and riverboat captains forged the American identity. They feel a moral responsibility to preserve this heritage and natural wealth, to ensure that their families and communities will continue to thrive.Unfolding as a journey down the Mississippi River, Rancher, Farmer, Fisherman tells the stories of five representatives of this stewardship movement: a Montana rancher, a Kansas farmer, a Mississippi riverman, a Louisiana shrimper, and a Gulf fisherman. In exploring their work and family histories and the essential geographies they protect, Rancher, Farmer, Fisherman challenges pervasive and powerful myths about American and environmental values.”
