The whisker cactus provides food for insects. It grows among rocks to camouflage itself as to avoid being eaten by hungry animals. There are many health concerns in the desert. A person who is traveling through the desert can suffer through many hardships, such as sunburns, sand storms, dehydration, snake bites and much more. If you ever travel to the desert, you should bring a ton of water with you.
Water can mean the difference between life and death.
Sunstoke can be prevented by drinking plenty of water. Don't ever drink alcoholic beverages in the desert. It too can cause water loss. If you ever find someone who is suffering from dehydration, take them to the nearest shade, give them water, tend to their needs, and get help as soon as possible. Snake bites are another concern in the desert.
