Limestone is at the center of everything on Sweden’s largest island, Gotland. The sedimentary rock lays the foundation for the water source of the Ojnare bog and creates jobs when it’s mined for building materials. It’s also at the center of a battle. The Limestone Conflict tells the story of a quarry’s quest for permission to mine in an untouched wilderness from the perspective of an activist, an industry employee and a neighbor. The controversial issue causes protests, disputes with police, threats and a media frenzy — and boils down to the age-old clash of environment versus industry.
