While the both pie charts illustrate the proportion of water being distributed around the world including fresh and saltwater, the bar chart compares three different countries in terms of the use of water.
Overall, a large amount of water is salt whereas most of the freshwater comes from Ice and Glaciers. Furthermore, water is mostly exploited by agriculture, especially in Egypt and Saudi Arabia.
As can be observed clearly, the proportion of salt water is 97%, which is higher than the figure for fresh water, with only 3%. Besides, Ice and Glaciers are the main places, which produce 79% of the world’s fresh water. Additionally, 20% of fresh water comes from the ground while only 1% is accounted for by the surface water’s figure.
Specifically, the use of water for agriculture in both Egypt and Saudi Arabia shares a similar proportion of around 80%, which is higher than that of Canada with only about 10%. In addition, the discrepancy among the figure for domestic in three surveyed countries is negligible, with roughly 15% is recorded. Lastly, accounting for nearly 80%, Canada’s industry uses the largest amount of water among three surveyed countries.
