Factory farming confines billions of animals in conditions that systematically deny their behavioral needs — making it the single largest source of preventable animal suffering globally.
Factory farming represents the largest single source of preventable animal suffering in human history. The systematic denial of behavioral needs, surgical procedures without analgesia, stocking densities incompatible with welfare, and genetic selection for production over health are inherent features of industrial animal agriculture rather than aberrations. Addressing factory farming welfare requires systemic change — in production standards, regulation, consumer demand, and food system economics — rather than incremental improvement of the worst practices alone.
