The two pie charts illustrate the distribution of water worldwide and of freshwater respectively, while the bar diagram shows water usage across the three countries Egypt, Saudi Arabia and Canada in three different categories: agriculture, domestic and industry.
In general, the majority of all water around the world is salt water. Regarding the sources of freshwater, ice and glaciers are the main contributors. Saudi Arabia and Egypt both mainly use water for agriculture, whereas Canada’s industry uses the most water.
The first pie chart shows that a great amount of global water is saltwater, standing at 97%, dominating the percentage of freshwater (3%). In the second pie chart, it is evident that water from ice and glaciers make up 79% of freshwater worldwide, which is almost fourfold of the amount of groundwater (20%). These sectors both trump over surface water, whose percentage is only 1%.
In terms of water usage, Canada uses the dominant number of 80% on its industry compared to agriculture and domestic (10% and 11% respectively). Both Saudi Arabia and Egypt mainly allocate their water towards agriculture. Interestingly, these two countries’ domestic water usage has the same percentage (approximately 12%); greater than the amount of water used in their respective industries.
