The provided pie charts reveal a comparison of worldwide water sources, while the accompanying table illustrates the purpose of water usage in three countries.
Overall, it is clear that salt water constitutes the vast majority of the world’s water supply compared to fresh water. Furthermore, the bulk of fresh water is found in the form of ice and glaciers. In terms of country usage, Egyptian and Saudi Arabian farming relies heavily on water, whereas Canadians mostly utilize their water for the industrial sector.
Regarding the pie charts, salt water represents by far the most significant share, accounting for 95% of the total, while fresh water comprises a mere 5%. Looking closer at fresh water, it is mainly locked inside the ice layer, which makes up about four-fifths of it. Furthermore, the least amount of fresh water exists on the surface, accounting for only a tiny fraction.
According to the table, agriculture accounts for the highest proportion of water use in both Saudi Arabia and Egypt, at 84% respectively. In contrast, these countries spend a significantly lower proportion of water on domestic and industrial processes. However, the Canadian industry is the only sector that utilizes four-fifths (80%) of the country’s water, while distributing nearly a tenth each to domestic and farming methods.
