Anna Casals is an art historian and has dedicated her professional life to bringing art and books closer to children. For more than 15 years she has been an editor of children's and young people's literature at Grupo Planeta. Paolo Ferri is an environmental engineer and founder of the start-up Up Wecity, an application that certifies the CO2 generated by our daily commutes and classifies them as sustainable or not. In this interview we talk about their passion for books and stories, something that has brought them together to create stories such as Cuentos para salvar el planeta, Yo cuido el planeta or La Isla. In this talk we talk about the importance of also having accessible and quality content for children on the major environmental problems we are currently facing.
