Essay topic: Talk about the importance of water
Since the beginning of time, water has continued to be an important
thing to all living things. Without water nothing could live. We may
change our food according to the climate of a place but we may find
no substitute for water. Man has always looked for pure fresh water
to slake his thirst.
Water not only quenches our thirst but it is also a source of food to
us. From the sea we catch large quantities of fish and other
creatures. We use water to irrigate our lands to produce crops. Many
parts of the world are dry and barren because there is no water there.
People in such places lead a very hard life. Even the plants and
animals find it a real struggle to survive. They can obtain water only
by some means of ingenuity. Water also helps to increase the
fertility of the land in several parts of the world. The alluvium that is
brought down by rivers is very fertile. Even electricity, which has
changed our lives completely, is produced by water-power in many
countries.
Further, water is an important means of communication. We use
waterways to carry our goods or trade. Water transport is cheaper
than land transport and in many remote regions, rivers are the only
means of communication. In many countries rivers are used to bring
down timber from the hilly regions to the lower regions where the
timber mills are. In this way much money is saved.
It is true, however, that water has also caused much destruction to
life and property throughout human history. Heavy rainfall, swollen
rivers and the angry waves of the sea have killed thousands of
people and destroyed homes and crops. Yet, water is indispensable
to life, and people everywhere are trying their best to bring water to
places where it is scarce, to control its flow in times of floods and to
make greater use of it.
