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 on 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.
Regarding the bar chart, the water usage trend in Egypt and Saudi Arabia is similar, with over 75 percent of water being used for agriculture. In contrast, Canada utilizes the majority of water for industrial purposes, with 80 percent. Additionally, the amount of water used for domestic purposes is under 20 percent in all three countries.
