While your burger might seem innocent, the shocking reality is that the land, water, and emissions used to produce it are quietly fueling a global environmental crisis, a fact underscored by statistics showing animal agriculture accounts for 14.5% of all human-caused greenhouse gases, uses 77% of farmland for just 18% of our calories, and consumes thousands of liters of water for a single serving.
Key Takeaways
- Animal agriculture accounts for 14.5% of global anthropogenic greenhouse gas emissions, equivalent to 7.1 gigatons of CO2-equivalent per year
- Beef production emits 99 kg CO2-eq per kg of protein, compared to 0.67 kg for peas
- Dairy cattle farming generates 20-30% of methane emissions from enteric fermentation globally
- Animal agriculture uses 70% of agricultural freshwater globally
- Producing 1 kg beef requires 15,415 liters of water
- Dairy production consumes 1,020 liters per kg milk
- Animal agriculture occupies 77% of global farmland but provides 18% calories, 37% protein
- Pasture land for livestock covers 3,449 million hectares globally
- Beef requires 326 m² land per kg protein, vs 1.9 m² for peas
- Beef pasture expansion drives 80% of Amazon deforestation
