Livestock farming produces more greenhouse gas emissions than the entire transport sector. That’s all the planes, trains, trucks, buses, cars, and boats on the planet. Exactly how much the livestock farming sector produces varies depending on which study you look at. The most conservative estimate is from the FAO (Food and Agriculture Organization of the United Nations) which puts it at 14.5% of all greenhouse gas emissions while the highest figure is a paper by Goodland and Anhang which estimates it to be 51% of all emissions.
Some people argue the FAO underestimate the value while Goodland and Anhang overestimate it. Whatever the real answer is we’re not going to tackle global warming without addressing the high emissions from livestock farming the solution for which is a plant-based diet. This is something most people don’t seem to want to acknowledge and I feel a sense of despair after my trip to meat-loving Spain. Even for those who live in Spain and voluntarily want to reduce their emissions the choices are dismal. How much more warming do we have to endure before we acknowledge the elephant in the room?
