Key Takeaways
- In the US, over 99% of farm animals are raised in factory farms where chickens are crammed into battery cages so small they can't spread their wings, leading to severe physical deformities and stress-related behaviors like feather pecking.
- Approximately 25 million hens in the US live in battery cages with less than 67 square inches of space per bird, equivalent to a single sheet of paper, causing chronic pain from broken bones.
- Pigs in gestation crates, measuring 2x7 feet, spend their entire pregnancies unable to turn around, resulting in muscle atrophy and psychological distress evidenced by bar-biting.
- Factory farming contributes 14.5% of global greenhouse gas emissions, primarily methane from cattle enteric fermentation.
- US factory farms produce 885 billion pounds of manure annually, equivalent to 5 times human sewage output.
- Poultry litter from factory farms pollutes waterways with phosphorus, causing algal blooms that kill 1,000+ km² of Gulf of Mexico dead zone yearly.
- Antibiotic resistance from factory farm runoff has led to 2.8 million resistant infections in US yearly.
- Factory farms use 70% of US antibiotics, contributing to 35,000 human deaths annually from superbugs.
- Campylobacter from factory chicken contaminates 1 million US cases of food poisoning yearly, hospitalizing 28,000.
- US factory farms slaughter 9.2 billion chickens yearly, 25 million per day.
- Globally, 80 billion land animals killed yearly for food, 99% from factory farms.
- US produces 10 billion broiler chickens annually from factory systems.
- Factory farms cost US taxpayers $38 billion yearly in subsidies and externalities.
- Factory farming receives 80% of US farm subsidies, $20 billion to top 10% producers.
