The pie charts provide a breakdown of total world water and the way fresh water is kept, while the bar chart compares the percentage of water used for three distinct purposes in three countries.
Overall, saline water accounts for a staggering portion of total world water reserves, whereas drinkable water comprises a mere proportion. Interestingly, a large part of fresh water available is kept in glaciers and permanent snows, which is followed by fresh ground water. The use of water is also noteworthy: although it is agriculture that consumes more water in Egypt and Saudi Arabia, water used for industrial purposes holds the lead in Canada.
The examination of pie charts reveals that saline water comprises an overwhelming proportion of total water reserves in the world at 97.50%, which is a stark contrast to fresh water with merely 2.50%. The latter is mostly kept in frozen form, which constitutes more than two-thirds of drinkable water available. Fresh ground water, albeit comparatively smaller, accounts for roughly a half of what is observed in frozen water at 29.90%. Notwithstanding this gap, underground ice and fresh renewable water sources comprise the respective figures of 0.90% and 0.30%.
The given bar chart, on the other hand, details how water is used in three countries. While agriculture is registered as the most water-consuming sector in Egypt and Saudi Arabia at 40% and 50% respectively, others do not consume as much water as agriculture does. A somewhat dissimilar pattern is observed in the case of Canada, where it is industry that crosses the 40% threshold. While agriculture comes second with 30%, domestic use accounts for almost a half at 17%.
