At the same time as when humans learned to cultivate crops and settle down in one place, they also learned to take care of animals that they caught in the wild. These animals provided humans with meat, milk and leather.

Gradually, humans learned to breed these animals into more docile, trusting companions. The farmed animals we know today are the result of this breeding process.

Many animals produce food for humans when they live. For example, a cow produces milk, a chicken produces eggs and bees make honey. In addition, many animals, such as cattle and pigs, are raised for their meat.
