प्रश्न
Is water conservation necessary? Give reasons.
उत्तर
Water is an indispensible resource for survival of humans. It constitutes about 70% of the human body weight. It is used for many purposes in daily life such as, drinking, bathing, washing clothes and utensils, etc.
Three-fourth of the earth's surface is covered with water but most of it is in saline form. Only 1% of the water is present as freshwater and the distribution of this water is very uneven. Moreover, people are now exploiting water indiscriminately which has led to its acute shortage in some areas of the world. So, it is very important to use this resource judiciously. Thus, conservation of water is necessary.
