Read the passage carefully and choose the correct answer.
A desert is a hostile, potentially deadly environment for unprepared humans. In hot deserts, high
temperatures cause rapid loss of water due to sweating, and the absence of water sources with which
to replenish it can result in dehydration and death within a few days. In addition, unprotected humans
are also at risk from heatstroke.
Humans may also have to adapt to sandstorms in some deserts, not just in their adverse effects on
respiratory systems and eyes, but also in their potentially harmful effects on equipment such as filters,
vehicles and communication equipment. Sandstorms can last for hours, sometimes even days.
Despite this, some cultures have made hot deserts 'their home for thousands of years, including
the Bedouin, Tuareg tribe, and Pueblo people. Modern technology, including advanced irrigation
systems, desalinization and air conditioning, has made deserts much more hospitable, In the United
States and Israel for example, desert farming has found extensive use.
In cold deserts, hypothermia and frostbite are the chief hazards, as well as dehydration in the
absence of a source of heat to melt ice for drinking. Falling through pack-ice or surface ice layers into
freezing water is a particular danger requiring emergency action to prevent rapid hypothermia.
Starvation is also a hazard; in low temperatures the body requires much more food energy to maintain
body heat and to move. As with hot deserts, some people such as the Inuit have adapted to the harsh conditions of cold deserts.
