The pie charts give information about how the world’s water is distributed, whereas the bar chart illustrates the percentage of water used in agriculture, domestic use and industry in three countries (Egypt, Saudi Arabia and Canada).
Overall, salt water makes up an overwhelming majority of the world’s water. Fresh water is made up of mainly water from ice and glaciers. While most water in Egypt and Saudi Arabia is used for agriculture, in Canada it is predominantly used for industry.
The pie charts show that 97% of global water is salt water compared to a mere 3% which is fresh water. Water from ice and glaciers accounts for 79% of all fresh water as opposed to ground water and surface water (20% and 1% respectively).
In terms of the use of water, both Egypt and Saudi Arabia use almost 80% of their water for agriculture in comparison to domestic usage and industry which account for approximately 15% and 10% respectively. The reverse is seen in Canada where only 10% of water is used for agriculture and domestic purposes in contrast to industry, which uses 80% of water in Canada.
