The document discusses environmental conditions, human life, and equipment needed in the Sahara Desert. The Sahara receives less than 3 inches of rain annually and temperatures can exceed 136°F, though its dryness rather than heat is what makes it a desert. Nomadic humans have lived in the Sahara for a long time by coping with the right resources, and essential equipment for the desert includes backpacks, water, sunglasses, hats, long pants, sunscreen, first aid kits, and flashlights.
