This week we discuss an important threshold the world has crossed. And, I speak with Professor Emily Kennedy of the Department of Sociology of the University of British Columbia about her recent paper titled "Accidental environmentalist or ethical elite? The moral dimensions of environmental impact." The paper is to be published in Poetics, and is co-authored by Christine Horne.

Segment 1 -- Emily Kennedy on "Accidental environmentalist or ethical elite? The moral dimensions of environmental impact"

Segment 2 -- Sociological and methodological reflections on the passing of an important threshold.
