The given line graph and table deep the water use in different sectors of earth and two nations Brazil and Congo in 2000.
Overall, there was a gradual increment in three sectors; agriculture, industry, and domestic. While agriculture was in the top among them in terms of consumption of water, on the other hand, the highest-populated Brazil consumed similarly high water than Congo.
In the line graph, agriculture consumed about 500 km3 water by 1900, which was increased gradually by following year and constituting 3000 km3 let 2000. It was the highest water-using sector throughout the period. Additionally, industrial and domestic sectors were dominated over the period. At the beginning, both sectors used less than 100 km3, with neglecting amount of using water increment up to 1950 for industry and 1970 for domestic sector. Both sectors started to increase and ended with about 100 km3 and 400 km3, respectively.
In the case of table, 176 million populated Brazil had 26,500 km2 agricultural land, consumed water about 359 m3, whereas Congo with small area of irrigated land with 5.2 million people used 8 m3 water in 2000, which was too much less than Brazil.
