The environmentalist George Monbiot argues that farming is the world\\u2019s greatest cause of environmental destruction, but few people want to talk about it. In Regenesis: Feeding the World Without Devouring the Planet he presents a vision for the future of food production. He tells Tom Sutcliffe that new ideas and technologies from soil ecology to laboratory-grown food could change the way people eat while regenerating the landscape.

But many farmers believe that they have been unfairly accused of ecological mismanagement, and that they are uniquely placed to restore the earth and provide a sustainable future. Sarah Langford has returned to her country roots after working for many years as a criminal barrister in the city. In her book, Rooted: Stories of Life, Land and a Farming Revolution she shows how a new generation of farmers are set on a path of regenerative change.

While Sarah Langford comes from a family of farmers, for many city dwellers it can be difficult to cultivate a connection with the earth. In her memoir, Unearthed: On Race and Roots and How the Soil Taught Me I Belong, Claire Ratinon, explores how she grew up feeling disconnected with the natural world and with family stories of slave ancestors forced to work the land. Through learning to grow her own vegetables and especially the food of Mauritius, she has finally felt able to put down roots.
