Most people in the desert are nomads or people who move place to place, but they raise sheep, goats, and camels. They move in their tents when the grass is eaten in a place. They usually settle in or near an oasis. Some people raise crops on irrigated land. They mostly eat rice which they carry and camel and sheep which move with them. They adapt by eating what they raise and by building new huts for their livestock every time they move themselves and their tents.
