Nature is Medicine -- Even in a Prison Cell

Nalini Nadkarni, a biology professor at the University of Utah who has pioneered techniques for studying tree canopy communities in tropical and temperate forests, started "Moss-in-Prisons," a project in which prisoners joined a research/conservation effort to counteract the destructive effects of collecting wild-grown moss from old-growth forests for the floral trade. "We learned that the inmates who viewed nature videos committed twenty-six percent fewer violent infractions than those who did not view them, a convincing result for the prison officers and administrators and for ourselves."
