“We continue to move in the wrong direction,” Rockstrom said, even as humanity enters the “most decisive decade” for its future. Rockstrom said at the conference earlier this month that growing evidence shows the situation has become more severe-an article published in Nature in April 2022 suggests that a sixth planetary boundary has now been crossed. The initial report from the EAT-Lancet Commission on food, planet, health showed that four of nine planetary boundaries had been crossed because of human activity. The goal was to figure out what kind of human diet could keep us within these limits. Leading scientists in nutrition, food science, agriculture, economics, and social science came together to figure out the impacts of current food systems on Earth’s planetary boundaries, which are global thresholds of nine biophysical processes of the Earth (things like ocean acidity, the accumulation of carbon dioxide in the atmosphere or the nitrogen cycle) that should not be exceeded so humanity can thrive and ecosystems can be preserved.
In 2019, researchers from all over the world created the EAT-Lancet Commission to address this. There’s no “1.5-degree target” for food systems, like the one included in the Paris Agreement for global temperatures, and mechanisms like an Intergovernmental Panel on Climate Change (IPCC) don’t exist for all the actors and sectors engaged in the global food system. It’s hard to give a clear, actionable path toward a sustainable food system.
