Without the water, we can't irrigate the plants. The plants cannot prepare their own food. Water is needed to prepare food. Plants prepare their owun food, by the means of photosynthesis. Without water, they cannot produce food. If there is water scarcity, we can't irrigate them. Thus, IT LEADS TO FAMINE AND DROUGHT. Thus, all the living beings will die without food. 
Hope this will help you.
