Can a 40-hour film of a Massachusetts garden or a project documenting rice growing over 40 years help us to understand our planet better? Who makes and who watches such projects? Matthew Sweet is joined by film historian Becca Voelcker who has watched projects recorded in Japan, Colombia, Scotland and America; Thomas Halliday, whose book Otherlands charts the changes in the earth's ecologies through deep time; and by environmentalist Rupert Read, who is Associate Professor of Philosophy at the University of East Anglia and has been thinking about what an eco-spirituality would look like. Plus, artist James Bridle, whose book Ways of Being investigates how far beyond humanity we can extend concepts like 'person', 'intelligence', and 'solidarity'.
