In episode two, we explore Notre Dame students' work on environmental issues in Ireland. None is more pressing than the role of bogs, a quintessential feature of the Irish landscape. They've been plowed over for generations to harvest the underlying peat for fuel. As the practice is phased out, one Notre Dame graduate student is studying how to restore these crucial pieces of carbon-storing habitat. But her work is only part of the University's effort to care for our common home.
