We need water to carry out various day-to-day tasks, such as: preparing meals, taking care of personal and domestic hygiene, fishing, using it for transportation, producing electricity, using it for irrigation, hydration, etc.
These activities can only be carried out with fresh water, which is found on the continents and is distributed in rivers, lakes, underground layers of the soil or in glaciers.
