As part of the roundtable, “Ethics and the Future of the Global Food System,” this essay discusses some of the major challenges we will face in feeding the world in 2050. A first challenge is nutritional: 690 million people (9 percent of the world's population) are currently undernourished, while 2.1 billion adults (28 percent of the population) are overweight or obese. The current global food system is insufficient in ensuring that the nutritious foods that make up healthy diets are available and accessible for the world's population. Moreover, by 2050, as the global population increases, food demand will increase by 50–60 percent. A fundamental challenge is meeting this demand while not wreaking irreversible havoc on natural resources, the environment, and planetary systems. A body of scientific research has coalesced around the need to reduce food loss and waste, adopt environmentally sustainable production practices, and shift toward plant-dominant diets. Other long-standing food system problems include deficits in providing fair wages and decent working conditions for food system workers, threats to smallholder farmer livelihoods, and tens of billions of animals kept in welfare-deficit confinement conditions. These food system challenges are bad states of affairs that matter from a variety of moral perspectives. In other words, there is a robust moral case for addressing these challenges. Yet concerted policy action in this area is insufficient and largely absent, pointing to the underlying challenge and complexity of political inertia.

9 As explained by the World Health Organization, “Wasting is defined as low weight-for-height. It often indicates recent and severe weight loss, although it can also persist for a long time. It usually occurs when a person has not had food of adequate quality and quantity and/or they have had frequent or prolonged illnesses. Wasting in children is associated with a higher risk of death if not treated properly. Stunting is defined as low height-for-age. It is the result of chronic or recurrent undernutrition, usually associated with poverty, poor maternal health and nutrition, frequent illness and/or inappropriate feeding and care in early life. Stunting prevents children from reaching their physical and cognitive potential.” “Malnutrition,” World Health Organization, n.d., www.who.int/health-topics/malnutrition#tab=tab_1.

12 As Jessica Fanzo writes in Nature: “The World Bank estimates that up to 115 million extra people will fall into extreme poverty (living on less than US$1.90 per day) in 2020 owing to the economic shocks of the pandemic. This, in turn, will have significant impacts on food security, nutrition and health. It is projected that 130 million more people will face acute food insecurity by the end of 2020, in addition to the estimated 135 million who faced it in 2019.” Jessica Fanzo, “Cooperate to Prevent Food-System Failure,” Nature, December 9, 2020, www.nature.com/articles/d41586-020-03444-5.
