To address hunger, many countries may have to increase carbon footprint

Obesity, undernutrition, and climate change are major global challenges that impact the world's population. While these problems may appear to be unrelated, they share food production and consumption as key underlying drivers. By recognizing the role of food production in climate change, this study examines the challenges of simultaneously addressing hunger and the climate crisis at both the individual and country levels.

A key finding of the study showed that a diet in which the animal protein came predominantly from low food chain animals, such as small fish and mollusks, had nearly as low of an environmental impact as a vegan diet. Researchers also determined that a diet that involved reducing animal food consumption by two-thirdstermed by study authors as "two-thirds vegan"generally had a lower climate and water footprint than the more traditional lacto-ovo vegetarian diet.
"Our research indicates there's no one-size-fits-all diet to address the climate and nutrition crises. Context is everything, and the food production policies for each country must reflect that," says senior author of the study, Keeve Nachman, Ph.D., director of the Food Production and Public Health program at the Johns Hopkins Center for a Livable Future and an assistant professor with the Bloomberg School's Department of Environmental Health and Engineering.
To counter these climate impacts and to address diet-related morbidity and mortality, the authors recommend, based on this report, that high-income countries accelerate adapting plant-forward diets. The authors emphasize that an examination of these diets and their environmental footprints allows for consideration of dietary recommendations or behavioral changes that would balance health and nutrition needs, cultural preferences, and planetary boundaries.
