The illustrations demonstrate how the water spreads across the world and the ways how three nations make use of water.
Overall, the majority of the water is salt water while fresh water only holds relatively little percentage. And most of the fresh water id in the form of glaciers. It can be seen that both Egypt and Saudi Arabia use the majority of water in agriculture, whilst canada makes the most use in industrial field.
Salt water occupies almost all the water in the world, taking up about 97%. Only the remaining 3% is accounted for fresh water. On top of that, over three quarters of fresh water is stored as glaciers. Second to glaciers, ground water takes up 20% of fresh water, leaving only 1% for surface water.
Looking into how the nations make use of water, agriculture is the one consuming most water in Egypt and Saudi Arabia, with around 80% and 78% respectively. In contrast, Canada consumes relatively little percentage of water in agriculture, which is only about 10%. And industries demand most of the water in this nation.
