70 Billion Land Animals Per Year

Understanding the scale of factory farming — and why it matters.

SCALE

Factory farming by the numbers

The scale is global, concentrated, and growing.

70B
Land animals slaughtered annually (FAO)
1–2T
Fish killed each year (est.)
9B
Chickens slaughtered in the U.S. annually
99%
U.S. farm animals raised in factory farms
TIMELINE

Lives compressed into weeks

Industrial systems shorten natural lifespans dramatically.

42 days
Chicken lifespan in factory farms (vs 5–7 years natural)
6 months
Pig lifespan in factory farms (vs 10–15 years natural)
4–5 years
Dairy cow lifespan (vs ~20 years natural)
DENSITY

Space per animal

Confinement is the default design feature of factory farms.

67 in²
Battery cage space per hen (less than a sheet of paper)
0.75 ft²
Average broiler chicken space per bird
2×7 ft
Typical gestation crate for a full-grown pig
WELFARE RESEARCH

What the science says about sentience

Modern neuroscience and behavioral research confirm capacity for conscious experience and pain.

2012
Cambridge Declaration on Consciousness: mammals, birds, and many other creatures have the neurological substrates for conscious states
Comparable
Pain sensitivity in chickens is comparable to mammals
Nociception
Fish show nociception and stress responses

Turn awareness into action

Small, evidence-based choices can spare thousands of animals.
