In each Letterbox series, people who have different points of view on a contentious food system topic exchange short letters, outlining their views and responding to the arguments of the other. The aim is to reach a clearer mutual understanding of the reasons for disagreement and to identify any areas of consensus.
If you would like to take part in a Letterbox exchange, please Contact Ruth.
