प्रश्न
Water is very precious for all living beings. What will happen in future if we do not save water now?
उत्तर
Water is the gift of nature, we must learn to honour it. If we do not use water judiciously and do not save it, there will be a scarcity of water and we will not be able to do various activities where water is required. It will also affect life on earth. Some of the problems that would be faced by people due to water scarcity are:
(i) Daily activities will become very difficult with the shortage of water.
(ii) Crop production will be affected resulting in an insufficient supply of food.
(iii) People would have to buy water at high prices.
(iv) People may drink dirty (contaminated) water which causes water-borne diseases such as cholera.
Due to water scarcity, sufficient water will not be available to plants. Plants need water to prepare their food through the process of photosynthesis. If water is not available to plants, the green character of the planet will be lost. This may mean the end of all life, for a world without plants will mean no food, no oxygen, not enough rain, and innumerable other problems.
