The dangerous Sahara desert

Temperatures are so high that most animals are nocturnal. This shows how hard it is for humans working in the day in the Sahara desert. Temperatures will be 40oC in the day and then below 0oC at night. No workers want to live and work in these conditions.
Water is life, but in the Sahara, it's a rare and precious commodity. With less than three inches of rainfall annually in some areas, finding water is a near-impossible task. Dehydration can set in quickly, making survival a formidable challenge.
Sandstorms, or haboobs, can strike without warning. These intense storms reduce visibility to zero, making it hard to see or breathe. They can disorient even the most experienced desert travelers.
