Embracing the finite: Making our way in an era of dwindling natural resources

Prof. Peter Vitousek

Ecologist Prof. Peter Vitousek explores how living in the Anthropocene, a time in which human activity has become the key driver of planetary health, will force us to make our way with diminished natural resources. Peter also asks what we can learn from the historical experience of Pacific Islanders, whose cultural and agricultural practices were shaped by a profound understanding that their immediate horizons were in fact the very limits of their worlds. Presented by Dr Andi Horvath.
