as we know that deserts are not suitable for living but still people live there. what are the conditions which make them do so?

Although deserts are not suitable for living but people still live there because: ●Human beings are very adaptable and they generally adapt to living conditions however harsh they may be ●They can make use of whatever resources are locally available to their best use ●The nomadic tribes have generally inhibited the deserts. Such tribes do not live at one place and move to different locations once condition get excessively harsh at a given place. ●The growing population makes its own demands and people in their endeavor to find better space, may actually opt for sparsely inhabited areas ●Places like the deserts offer excellent natural surrounding and beauty and are hot spots for tourism. Unless people live there, this economic aspect cannot be developed
