Planting trees is very important for the environment. Some people says trees should be planted in the vacant areas of cities and towns, while other says housing facilities should be build instead. Do you agree or disagree?

The graph illustrates how the amount of

water

used worldwide changed between 1900 to 2000, while the table shows information about

water

expenditure by Brazil and Congo in the year 2000. Overall, it is evident that

water

consumption trend to increase all sectors, whereas the agriculture section increased the biggest amount. In the graph, increasing from around 5000 km3 in the year 1900 to almost 10000 km3 in 1950,

water

expenditure in the agriculture section

then

peaked at approximately 3000 km3 in 2000.

On the other hand

,

water

used in industrial

use

and domestic

use

sections

also

increased, but consumption was minimal until mid-century. From 1950 onwards, industrial

use

grows moderately just over 1000 km3 at the end of the century, while domestic

use

rose more slowly than industrial

use

to only about 300 km3, both far below the level of consumption by agriculture.

Moreover

, the table reveals that Brazil, which population was 176 million, used 359 m3

water

for irrigating land (26500 km2).

In contrast

, Congo consumed only 8 m3 of

water

because of lower people (5.2 million) and fewer irrigate land (100 km2).
