The given pie charts illustrate the allocation of salt and fresh water in the world, while the provided bar chart gives information about the percentages of water each country utilizes for different purposes.
The initial impression from the charts is that freshwater occupies a very small proportion of the total amount of water in the globe, whereas the majority of freshwater exists in the frozen form. A noticeable feature in the bar chart is that the majority of water is used in agriculture in Egypt and Saudi Arabia, while Canada utilizes most water for industry.
Looking at the two pie charts, it is apparent that salt water accounts for almost all of the global water reserves, constituting 97 percent compared to a mere 3 percent of freshwater. Within this small amount of freshwater in the world, nearly 80 percent is ice and glaciers, which is fourfold the percentage of groundwater. Regarding surface water, this proportion makes up the remaining 1 percent in the chart.
With regards to the bar chart, the water usage tendency in Egypt and Saudi Arabia is equivalent, with each of these proportions of Agriculture being more than 75 percent. Meanwhile, Canada utilizes the majority of water for industrial purposes, with 80 percent. On the other hand, the amount of water for domestic use is under 20 percent in all three countries.
