Step-by-step explanation:
Pastoralism is a sociocultural complex that revolves around the herding of animals. It is a subsistence mode in which cultures are shaped by a preoccupation with herds. The size of a family's herds is a measure of wealth and animals are used for various purposes such as meat, milk, cloth, and leather. Mobility is another feature of pastoral societies, as herders constantly move their animals to fresh pastures. Pastoralists also possess extensive knowledge about animals and the environment, allowing them to maintain a sustainable way of life. They often combine pastoralism with farming and engage in trade with neighboring groups.
