Deserts

Water is the life. Water keeps people alive and helps people to be healthy and wealthy. But we hear a great number of stories when water may disappear and people will feel constant thirst, etc. But there are places on our planet where there is no water and where people may die because of its lack. And this place is a desert.
There are a lot of legends and stories, according to which people died in deserts without water under the sun in sands. It is very easy to get lost in the desert. That is why people recommend to hire a good guide if you are going to desert and to take as many water as possible. Imagine several days without water in a desert where you got lost. It is the real hell.
The only plants that may be found in deserts are cactuses. There is no special fauna in deserts. Only a couple of scorpions may be found in it. So a person who got there may die either from the lack of water or food.
Sahara is the most famous desert in the world that is situated in the northern part of African continent.
When a person is thirsty and the sun influences him/her, mirages may appear that are the illusions of oasis. But when the illusion melts away a person understands that it was only the mirage.
But oasis really exists. Oasis may be found in deserts and is a little island with a pond surrounded by a great number of plants, where strangers may have a rest and fill up their bottles with water.
It may sound strange but deserts are used in agriculture. Besides, it is the place with developed beef cattle. Cultivating is developed near the rivers and is possible only with frequent sprinkle of crops. Some deserts are very rich in oil and gas deposits. For example, the deserts of Asia are especially rich in treasures of soil.
Still deserts are the extreme areas of the planet and they demand attention and carefulness. If you are going to travel across the deserts be very careful, as the lack of water may not be the only problem. A great number of reptiles such as snakes and scorpions may harm you.
