About 15 million deaths could be avoided each year and agricultural emissions could drop by 15% if people worldwide shift to healthier, predominantly plant-based diets, according to the human health, climate change, biodiversity and people’s working and living conditions. Their conclusion: Without substantial changes to the food system, the worst effects of climate change will be unavoidable, even if humans successfully switch to cleaner energy. “If we do not transition away from the unsustainable food path we’re on today, we will fail on the climate agenda. We’ll fail on so many pathways,” said study co-author Johan Rockström, who leads the Potsdam Institute for Climate Impact Research. Key points from the latest report:A ‘planetary health diet’ could avert 15 million deaths every yearThe first EAT-Lancet report proposed a “planetary health diet” centered on grains, fruits, vegetables, nuts and legumes.
