crops and farm stock and is used in the
manufacture of many products.

water.
 Throughout history there have been many
occasions when thousands of people have died
because disease-causing germs have been spread
through a community by a polluted water supply.

5.  Actually, only 1% of the world's water is
usable to us. About 97% is salty sea water,
and 2% is frozen in glaciers and polar ice
caps. Thus that 1% of the world's water supply
is a precious commodity necessary for our
survival. Dehydration will kill us faster than
starvation . lack of it could cause both
dehydration and starvation.

water can keep us alert and active during the day.

8. The water which falls to the ground as rain or hail. Can be
collected from a special area called a catchment. The
catchment feeds water into a holding area via rivers,
streams and creeks. The water is then stored in a natural or
artificial manmade barrier called a dam. Dams are usually
placed at the lower end of a valley.
Catchment areas are usually far away from towns or cities
to lessen the chance of the water being polluted. There are
laws which control human activities, such as farming and
recreation in catchment areas and on dams to make sure
that water supplies are kept potable.
