Q. Why do human beings sweat?
Ans. The human body is a unique creation of God. Sweating is a unique feature of it. Human beings sweat in order to keep their body temperature constant. In hot climates, they are unable to bear the high body temperature and thus they begin to sweet. This sweating cools their body and regulates their temperature. Thus, they feel comfortable even in the hot summer. This is one of the reason why human beings require more and more water in summer.
Q. The desert plants and animals have adapted themselves to the scarcity of water in deserts. How?
Ans. The desert plants and animals have adapted themselves to the scarcity of water in deserts as they have learnt how to adapt themselves to the climatic conditions of the desert and this is the reason why they require less water than most plants and animals. Some plants are strong enough, to have the capacity to store water in their stems, roots and other parts. They constantly suck moisture from the ground. The desert animals, too are able to consume and store more water but there are some animals like camels who can survive without water for many days. The smaller animals, on the other hand, face this adversity by not exposing themselves to heat during the day. Also, they eat other smaller animals from whose meat they could gather moisture. In this way, they have adapted themselves to the scarcity of water.
Q. Deserts are an important part of nature’s great plan. Discuss.
Ans. It is true that deserts are an important part of nature’s great plan. A large portion of the Earth is covered with deserts. The land without water or vegetation too has a purpose to serve humanity. Deserts remind us of the beauty with which God has blessed human beings as man takes much rest and relaxation in the lap of nature. It is quite impossible for human beings to understand the significance of light in absences of darkness, similarly we can appreciate the beauty of nature by understanding barrenness as another alternative. So it can be claimed that the natural landscapes of deserts are things of beauty for human beings to appreciate the scenic beauty in nature and deserts.
