What will happen if we do not conserve water and it does not rain for years in a particular region?
Drought
If it does not rain for one to two years, the soil continues to lose water by evaporation and transpiration and the groundwater level keeps dropping. As the soil becomes dry and it is no more possible to draw underground water through pumps and wells, there will be a scarcity of water for general use and agriculture. This will lead to drought.
