On Start the Week Andrew Marr talks to the American writer, poet and farmer Wendell Berry. In his latest collection of essays, The World-Ending Fire, Berry speaks out against the degradation of the earth and the violence and greed of unbridled consumerism, while evoking the awe he feels as he walks the land in his native Kentucky. His challenge to the false call of progress and the American Dream is echoed in the writing of Paul Kingsnorth, whose book Confessions of a Recovering Environmentalist eschews the grand narrative of a global green movement to focus on what matters - the small plot of land beneath his feet. Kate Raworth calls herself a renegade economist and, like Berry and Kingsnorth, challenges orthodox thinking, as she points to new ways to understand the global economy which take into consideration human prosperity and ecological sustainability.
