This paper examines the complex interactions between food systems, diets, and the environment. We discuss the challenges facing the food system as a result of environmental degradation and climate change. We review the state of current diets and their effects on human health outcomes. As we consider paths forward, we examine holistic solutions that align nutrition, health, and environmental goals. Finally, we identify ethical questions relevant to the changing global food system. We consider our moral obligations to other people – both now and in the future – and the planet, and we posit that eating is an ethical act requiring reflection at all scales
