A day in a Desert short story
Answers
Those of us who live in regions covered with forests and surrounded by hills may find it difficult to imagine what a desert is really like. The popular belief is that it is an endless stretch of sand where no rain falls and, therefore, no vegetation grows. It is dry, hot, waterless and without shelter. But this is not entirely correct. For those who have studied it, the desert can be a beautiful place. It is the home of a variety of people, animals and plants that have learnt to live under very hot and dry conditions.
True, the ground is not always hidden by a cover of grass, plants or trees as it is in other climates. But whenever it rains, which is rare, desert flower buds open up, and the sight can be as rewarding as that of any tropical garden.
A desert is not always a flat, unchanging, useless area of dry sand. It may have mountains and hills. It may have an oasis, big or small. An oasis is like a green island in the middle of a desert where a spring or well gives plants and trees a better chance to grow. A desert may be hot like Thar or cold like Ladakh. But, generally speaking, if a place has little or no water and vegetation, people usually call it a desert.
Some deserts are almost totally without water. In such places, strong winds raise huge amounts of sand and deposit them as heaps. These are called 'sand dunes', and they can shift and move endlessly across the desert. Few plants can survive in such dry, shifting sands.
All living things need water in order to survive. The few plants and animals that live in deserts have developed the ability to require less water than most plants and animals. The camel, popularly known as the 'ship of the desert' can drink a lot of water at one time. Camels can do without water for days together. The reason is that they sweat very little. We sweat because we must keep our body temperature constant. When it gets hot, our sweat cools the body. Camels can stand high body temperatures. They don't need to sweat and can, therefore, store the water they drink for long periods of time.
The smaller desert animals do not drink water. They stay in underground tunnels during the hot day and come out only at night to eat. Some of them eat other animals and get the water they need from the moisture in the meat. Others eat plants and seeds, and get the water they need from plant juices.
Desert plants also change themselves according to the life they lead. Cactus plants store water in their thick stems. Their roots lie close to the surface of the ground and quickly take in the tiny drops of water from the light rains that occasionally fall.
The major feature of all deserts is, of course, dryness and differences of temperature. In hot and wet climates, the moisture in the air acts like a blanket and protects the earth's surface from the hot rays of the sun. The absence of this blanket in desert lands causes the deserts to heat up rapidly during the day and to cool down rapidly at night.
Deserts are an important part of nature's great plan. They are there like the thick forests and the deep oceans. Just because they are hot and dry, one should not look upon them as useless parts of the earth.
