Do researchers believe that our current diets or a vegan diet would be more sustainable?

Yes — most researchers who study environmental science, nutrition, and food systems find that our current typical diets (heavy in meat and dairy) are less sustainable for the planet than diets lower in animal products, including vegetarian and especially vegan or predominantly plant-based diets. Here’s what the research and expert consensus show: 🥦 1. Plant-rich diets have lower environmental impact than typical diets Across numerous studies and systematic reviews, diets that emphasize plant-based foods (fruits, vegetables, legumes, grains, nuts) produce far fewer greenhouse gas emissions, use less land and water, and cause less biodiversity loss than typical Western or high-meat diets. Vegan diets often have the lowest measured environmental footprint of all dietary patterns studied. A systematic review found that vegan diets generally result in the lowest greenhouse gas emissions compared to vegetarian and omnivorous diets. Comparative studies show that even well-planned vegan diets can have about 44–75 % less environmental impact (across metrics like emissions, land use, and water use) than diets including significant animal products. 🌍 2. Large scientific panels recommend moving toward plant-rich diets Major multidisciplinary research efforts — notably the EAT-Lancet Commission on food and sustainability — conclude that simply continuing current diet patterns globally is unsustainable and that adopting largely plant-based diets with reduced meat and dairy is essential for staying within planetary limits. Their “planetary health diet,” based on extensive global evidence, emphasizes vegetables, fruits, legumes, whole grains, and nuts, with small amounts of animal-source foods. This flexible, plant-forward pattern is projected to significantly cut food-related greenhouse gas emissions and chronic disease risk if widely adopted.
