In front of an audience at the Hay Literary Festival Tom Sutcliffe talks to The archaeologist and presenter of the hit TV show, The Great British Dig, Chloë Duckworth, who explains how every object tells a story. She reveals how even the rubbish our ancestors threw away can offer a window on the past and forge a connection with the present day. Business journalist Saabira Chaudhuri's new book Consumed, examines how companies have harnessed single-use plastics to turbocharge their profits over the last seventy years. Consumer goods makers have poured billions of dollars into convincing us we need disposable cups, bags, bottles, sachets and plastic-packaged ultra-processed foods. Taking in marketing, commercial strategy and psychology, she explains just how we got here. The paleobiologist Sarah Gabbott is more interested in looking at how what we throw away today becomes the fossils of tomorrow. Discarded (co-authored with Jan Zalasiewicz) highlights the cutting-edge science that is emerging to reveal the far-future human footprint on Earth.Producer: Katy Hickman
