There is increasing research on the effects of industrial livestock production on the environment and human health, but less on the effects this has on animal welfare and ecological justice. The concept of ecological justice as a tool for achieving sustainability is gaining traction in the legal world. Klaus Bosselman defines ecological justice as consisting of three elements: intragenerational justice, intergenerational justice, and interspecies justice. While the first two have been extensively discussed, interspecies justice has received less attention. It is argued that the neglect of interspecies justice in the practice of industrial livestock production leads to both intragenerational and intergenerational injustices. The article focuses primarily on an animal welfare perspective, addressing the extreme harm and oppression of animals entailed by their commoditization for industrial food production. The destructive impact of this mode of food production on environmental resources and its massive contributions to climate change also lead to the impoverishment of the food, environmental, social, and economic health of present and future generations. The article describes the legal mechanisms that have permitted, and indeed encouraged, the move to industrial livestock production, and suggests changes that could reduce the three kinds of ecological injustices which industrial livestock production produces.
