Natural life span: 20+ years
Factory farm life span: 0–20 weeks or 12–14 months
Veal calves, the inevitable byproduct of the dairy industry, are slaughtered at a few months old and as young as a few hours old - and are sometimes even cut out of their mothers' stomachs. Cows used for beef don't live much longer. Like most factory-farmed animals, they're genetically designed to gain weight far more quickly than they should, and are killed at around 1 year old.
