The provided pie charts delineate the amounts and sorts of water in the world, whereas the column graph portrays the proportion of freshwater utilized for three different purposes in Egypt, Saudi Arabia, and Canada.
Overall, it is discernible that fresh water is a very precious commodity as it only accounts for 2.5% of the total water on planet Earth, and out of that a very small fraction is usable, which is used for domestic, industrial, and agricultural use.
The first pie chart clearly illustrates the stark disparity in the global distribution of water resources, with the predominant majority (97.50%) comprising saline water, while the remaining fraction (2.5%) constitutes freshwater. Examining deeper into the composition of freshwater, the second pie chart reveals that the majority (69.80%) is locked away in glaciers and permanent snow cover, while a significant portion (29.90%) is stored underground as groundwater. The minuscule fraction (0.90%) of freshwater exists in the form of underground ice, and an even smaller proportion (0.30%) represents the readily accessible freshwater resources available for human use.
The bar graph provides a comparative analysis of water usage patterns across different countries. In Egypt, the agricultural sector emerges as the dominant consumer, accounting for a substantial 40% of total water usage, while domestic and industrial sectors claim 10% and 8% respectively. A similar trend is observed in Saudi Arabia, where the agricultural sector dominates with a 50% share, followed by industry at 18% and domestic use at 8%. Notably, the data reveals that Canada exhibits a distinct water usage profile, with the industrial sector as the largest consumer at 47%, followed by agriculture at 30%, and domestic use at around 18%. These contrasting patterns underscore the diverse socioeconomic and environmental factors that shape water resource management strategies across different nations.
