Question

Read the following text.

Water – Consumption increasing; resources shrinking

The demand for water is rising as population, economic activity and agricultural irrigation grow. However, worldwide resources of accessible water are decreasing, due to overuse or pollution. The balance between demand (consumption) and supply (resource) is becoming unstable.

More than 30 countries suffer from serious chronic water shortage, and groundwater is increasingly being used to cover the demand.

Agriculture is the greatest single worldwide consumer of water (70%), followed by industry (20%) and homes (10%). Considerable efforts have been made to reduce consumption in industry and homes; but much remains to be done in improving the efficiency of irrigation. The increasing use of nonrenewable groundwater for the irrigation of marginal farmland in arid zones is of particular concern.

The proportion of water used in these three sectors varies from region to region, and between levels of economic development. In Europe and North America, water is used primarily by industry. In Asia and Africa, agricultural irrigation is the primary consumer. Thus, in many semi-arid and arid regions about 30% of groundwater is extracted for irrigation, and the trend is increasing.




Based on the text above, check if the statements are true (T) or false (F). Then, mark the correct alternative.

I. Due to water shortage, the use of groundwater is increasing. ( )

II. Worldwide water supplies are unlimited. ( )

III. Demand for clean water increases continually in line with world population growth. ( )

IV. The use of irreplaceable underground water is stable in semi-arid regions. ( )

V. A lot has been done to improve the efficiency of irrigation systems. ( )
