If we are to attain a sustainable future, humanity will need to make drastic changes towards a life based on sustainability in all areas, especially in the economic sector, including food production. The task of educating for sustainability needs to include food producers (farmers and livestock breeders). This article describes an educational experience carried out within the framework of a proposal presented in the "Second Call for Grants to Promote University-Company Projects" at the Technological Campus of Algeciras (Spain). It consisted of conducting in-depth interviews with farmers and livestock breeders, identifying the practices in the daily management of their farms, and having them participate in an education and training event in which they shared their knowledge. It was not an easy task because food producers have systematically been attacked by currents of opinion that blame them for causing greenhouse gas emissions. We adopted an approach based on empathy and on encouraging sustainable food production practices.
