As human power keeps growing, our ability to harm or benefit other animals grows with it

Yuval Noah Harari writes: This is the basic lesson of evolutionary psychology: a need shaped thousands of generations ago continues to be felt subjectively even if it is no longer necessary for survival and reproduction in the present. Tragically, the agricultural revolution gave humans the power to ensure the survival and reproduction of domesticated animals while ignoring their subjective needs. In consequence, domesticated animals are collectively the most successful animals in the world, and at the same time they are individually the most miserable animals that have ever existed.

The situation has only worsened over the last few centuries, during which time traditional agriculture gave way to industrial farming. In traditional societies such as ancient Egypt, the Roman empire or medieval China, humans had a very partial understanding of biochemistry, genetics, zoology and epidemiology. Consequently, their manipulative powers were limited. In medieval villages, chickens ran free between the houses, pecked seeds and worms from the garbage heap, and built nests in the barn. If an ambitious peasant tried to lock 1,000 chickens inside a crowded coop, a deadly bird-flu epidemic would probably have resulted, wiping out all the chickens, as well as many villagers. No priest, shaman or witch doctor could have prevented it. But once modern science had deciphered the secrets of birds, viruses and antibiotics, humans could begin to subject animals to extreme living conditions. With the help of vaccinations, medications, hormones, pesticides, central air-conditioning systems and automatic feeders, it is now possible to cram tens of thousands of chickens into tiny coops, and produce meat and eggs with unprecedented efficiency.

The fate of animals in such industrial installations has become one of the most pressing ethical issues of our time, certainly in terms of the numbers involved. These days, most big animals live on industrial farms. We imagine that our planet is populated by lions, elephants, whales and penguins. That may be true of the National Geographic channel, Disney movies and children’s fairytales, but it is no longer true of the real world. The world contains 40,000 lions but, by way of contrast, there are around 1 billion domesticated pigs; 500,000 elephants and 1.5 billion domesticated cows; 50 million penguins and 20 billion chickens.
