Factory Farming and Industrial Livestock

Factory farming provokes relentless controversy, with over 70 billion land animals raised annually in confined operations—battery cages, gestation crates, and beak trimming remain standard despite overwhelming evidence of animal sentience. The practice generates 14.5% of global greenhouse gas emissions, more than the entire transportation sector, and it is cheaper than the typical free-range alternative by 40%, creating a cost-driven ethical dilemma. Consumers who switch to plant-based diets reduce animal suffering by 95%, a statistic that outpaces the impact of any single animal welfare policy. This industrial model is the leading source of antimicrobial resistance, using 73% of global antibiotics, which fuels a crisis that #8 (Antibiotic Use in Livestock) addresses more explicitly.
