Regenerative agriculture aims to restore lost health in the soil, microbes, animals, and social communities while at the same time building new and resilient connections between those same stakeholders. Given these aims, it is important that both regenerative agriculture proponents and practitioners, as well as policies animated by regenerative agriculture, develop and work from a fully developed idea of justice. This chapter examines justice starting from moral philosophy, developing a thicker, personalistic account of justice in relationship to food and agriculture. Within that account, we extend the idea of an environmental witness; that is, the idea that some people are practicing agriculture with justice in mind and that we can see them and learn from them. We then conclude with the example of the Catholic Worker farms as an example of an environmental witness worthy of learning from in the context of regenerative agriculture prospects.
