Pastoralist: A pastoralist is an individual who watches over and grazes various types of large domesticated animals. Pastoralists can be found in various parts of the world and care after a diverse assortment of herbivores including: cattle, sheep, llamas, goats and reindeer.
The animals are usually unique to their region; for instance in the Middle East and Arabia camels and horses are the most common animals for pastoralists to care for. Many pastoralists are nomadic in order to be able to provide food and water for the animals they support. These pastoral nomads set up camp at varying areas from season to season and live in simple dwellings that they can assemble and disassemble as needed.
