Perguntas frequentes

What is factory farming?
Factory farming is the intensive confinement of animals at high density to maximise output per unit of land, labour and feed. It relies on standardised housing, routine veterinary inputs and rapid growth genetics.
How many animals are raised on factory farms?
Most farmed land animals worldwide — commonly estimated at around 70–90% depending on region and species — are raised in intensive systems rather than pasture-based ones.
Why is factory farming a public health concern?
Dense confinement raises disease-transmission risk, drives antimicrobial use, and concentrates manure and air pollution near farming communities.
