The fate of industrially farmed animals is one of the most pressing ethical questions of our time. Tens of billions of sentient beings, each with complex sensations and emotions, live and die on a production line.
What makes the existence of domesticated farm animals particularly cruel is not just the way in which they die but above all how they live. Two competing factors have shaped the living conditions of farm animals: on the one hand, humans want meat, milk, eggs, leather, animal muscle-power and amusement; on the other, humans have to ensure the long-term survival and reproduction of farm animals. Theoretically, this should protect animals from extreme cruelty. If a farmer milks his cow without providing her with food and water, milk production will dwindle, and the cow herself will quickly die. Unfortunately, humans can cause tremendous suffering to farm animals in other ways, even while ensuring their survival and reproduction. The root of the problem is that domesticated animals have inherited from their wild ancestors many physical, emotional and social needs that are redundant in farms. Farmers routinely ignore these needs without paying any economic price. They lock animals in tiny cages, mutilate their horns and tails, separate mothers from offspring, and selectively breed monstrosities. The animals suffer greatly, yet they live on and multiply.
