The Humane League
Leads corporate campaigns to end the worst confinement practices and improve conditions for farmed animals.
DonateThe scale of suffering
Factory farming is the central driver of animal suffering today.
Each year, roughly 75+ billion land animals are slaughtered for food, and estimates for fish killed for food range from the hundreds of billions to over a trillion. Most farmed animals live in intensive systems that prioritize efficiency over welfare, with confinement and crowding as the norm.
The good news: a handful of highly cost-effective interventions can spare vast numbers of animals.
Why it matters
- 75B+ Land animals slaughtered annually
- 0.79–2.3T Wild-caught fish killed each year (est.)
- 29–149B Farmed fish killed each year (est.)
Estimates vary by methodology, but the scale is unmistakable.

Most effective interventions
Ranked by impact per dollar
Evaluators prioritize strategies that shift large food systems at low cost. Corporate campaigns and alternative proteins can affect millions of animals per change, while individual actions add up meaningfully but scale more slowly.
-
Farmed animal advocacy & corporate campaigns
Corporate cage-free and welfare commitments can rapidly improve conditions for millions of animals.
-
Alternative proteins support
Accelerating plant-based and cultivated products reduces demand for animal farming at scale.
-
Individual diet change
Shifting toward plant-forward diets directly reduces demand for animal products.
-
Welfare legislation
Policy wins can lock in broad improvements and guard against backsliding.

Key facts
Evidence you can point to
Industrial systems dominate
Most farm animals are raised in intensive systems that keep animals confined indoors at high densities.
Commitments are growing
Tracking of 1,147 food-related companies found 92% of cage-free commitments with deadlines of 2024 or earlier were fulfilled.
Diet change is measurable
ACE estimates a plant-based diet spares about 105 vertebrates per person per year (2018 data).
Leg disorders are a major welfare issue
A large survey of commercial flocks found over 27% of birds had poor locomotion, with some nearly unable to walk.
