Practice According to the chart.

The graph illustrates the changes in water usage according to three different purposes worldwide from 1900 to 2000 and the table presents two different countries, Brazil and Congo, individual water consumption with population and the total of irrigated land in 2000.

The most significant water usage sector was agriculture and the water usage for agriculture increased over the periods sharply. In 2000, water usage reached around 3000 KM3, which is almost 6 times higher than the water usage for agriculture in 1900. The industrial use of water in the global part was the second highest part while the least used part of universal water was the domestic part.
Meanwhile, the two countries' water consumption shows significant differences. Individual water consumption in Brazil was 359 M3 in 2000 while Domestic republic of Congo was 8 M3. The figure of the individual water consumption seems to be closely relevant to irrigated land size since Brazilian irrigated land size of 26,500 KM3 was 265 times bigger than Democratic Republic of Congo.

In brief, the water usage of every sector increased globally and individual water consumption is closely related to irrigated land size.

Hello DongPan,

The text is generally understandable and I think you have included most of the main points although I think that you should also include the fact that global water usage started to increase more dramatically in the 1940s. I would also add that individual water consumption appears to be closely related to irrigated land size.
