Desert conditions are really harsh, there is no permanent water supply and the weathers are extreme, how can man tolerate this? For example, if a man stays in the desert for the whole day, without any special equipment, he can die immediately by the next morning because of the explosive temperature and the serious shortage of water and salt.
But surprisingly, some men can penetrate and even prosper in deserts! This is because of cultural adaptations, like water can be obtained by digging or drilling or simply getting water from other places. But the temperature is another problem, therefore clothing is very important. Loose-fitting, flowing garments are suitable in the intense heat of the desert. But in places with freezing nights, long-sleeved woolen nightshirts will be worn to protect the person from daytime heat and provide warmth in the night. Though there are many ways to solve the problems of living in the arid land, people cannot live in a certain area of the desert permanently, for when the sources of a particular area are used up, then they will have to move to another place to search for sources, therefore they have to live as NOMADS. Nomadism is a cycle, as people move to this place to another, they may go back to the previous place again after a length of time, for living things there will grow again after some time. But nomadism does not mean a total change of the habitat or unrestricted, unplanned wandering, it just indicates that there are no permanent place of residence. These nomads live very independently in the desert, not needing any help from other places, but domestic stock is most important. The sheep, goats and camels are their food, their traveling tools. Besides of these animals, they hunt for part of the year and others cultivate the land there for growing primitive crops.
