The most comprehensive study of food systems (Poore & Nemecek, 2018, Science) analyzed 38,700 farms across 119 countries and found that a vegan diet reduces food-related emissions by 73%, land use by 76%, and water pollution by 49% compared to a typical omnivore diet. An average omnivore's food generates 2.5 tonnes CO2e/year, while a vegan's generates 1.0 tonne. Animal agriculture uses 77% of global agricultural land but provides only 18% of global calories. Beef requires 20× more land and emits 20× more greenhouse gases per gram of protein than plant proteins like beans. A vegan diet saves approximately 1,100 liters of water, 20 kg of grain, 3 m² of forest, and one animal life per day. Even partial reduction helps: "Meatless Monday" reduces weekly emissions by ~14%. The Oxford Martin School found that global adoption of a vegan diet could reduce food emissions by 70% and save 8 million lives by 2050.
