Most of the animals we farm are rarely seen. Here's who they are.
The vast majority of farmed animals live inside large, industrial systems. Behind the numbers are individuals with rich emotional lives, strong social bonds, and the capacity to suffer.
Numbers are staggering, but each line represents sentient beings with their own needs and behaviors.
Each card highlights a few science-backed traits and the conditions they face.
Scale: ~70 billion killed per year.
Natural lifespan: 10–15 years in nature vs ~6 weeks in factory farms.
Mind: Can recognize 100+ faces, pass mirror tests, and show maternal behavior.
Welfare: Pain sensitivity is well documented, yet fast growth and confinement are common.
Scale: ~1.4 billion killed per year.
Mind: Intelligence comparable to a 3-year-old child; outperform dogs and chimps in some tests.
Social: Form complex bonds, communicate with dozens of vocalizations, and love to play.
Welfare: Many breeding pigs endure gestation crates that prevent turning around.
Scale: ~1 trillion killed per year (mostly wild-caught).
Sentience: The 2012 Cambridge Declaration on Consciousness includes fish.
Pain: Evidence of nociceptors and pain-related behavior is robust.
Learning: Memory lasts longer than the “3-second” myth; social learning is common.
Scale: ~300 million killed per year.
Bonding: Strong maternal ties; cows may vocalize and show distress when calves are taken.
Mind: Long memories, problem-solving skills, and lifelong friendships are well documented.
Welfare: Stress increases in unfamiliar environments and during transport.
Scale: ~400 billion per year (aquaculture).
Sentience: Evidence of nociception and avoidance learning (Barr et al. 2008).
Welfare: Most are boiled or freeze-killed without stunning — sentience is actively debated but precautionary principle applies.
Numbers: The largest single animal group killed by humans by count.
Scale: ~8 billion in production at any time globally.
Lifespan: 1–2 years in production (natural 5–10 years).
Welfare: Male chicks are culled at birth (approximately 6–7 billion/year); females crowded in battery cages or barns.
Mind: Same cognitive abilities as chickens, plus evidence of empathy toward their chicks.
Sentience research increasingly shows that many farmed animals experience pain, fear, and complex emotions. The 2012 Cambridge Declaration on Consciousness affirmed that non-human animals, including birds and fish, have the neurological substrates needed for conscious experience. The Farm Animal Welfare Council’s Five Freedoms further outlines a baseline for humane treatment: freedom from hunger and thirst; discomfort; pain, injury, or disease; fear and distress; and freedom to express normal behavior.
In 2023, the New York Declaration on Animal Consciousness was signed by 40+ prominent scientists, affirming a realistic possibility of conscious experience in all vertebrates and many invertebrates, including crustaceans and insects.
