For future
generations it will be increasingly vital to have not only specialized
knowledge but also a holistic and integral awareness of water. Since in this
book it is the water that speaks, thus, the book is written in the first
person, as if the narrative were made by the water itself. It is addressed to
young people in a synthetic and poetic language, permeated by illustrations.
The book
describes, in five parts, a journey through the complete water cycle in the
environment, its movement, its presence in living bodies, in culture, and
issues related to its use.
The first
part invites the reader to approach water, to know its travels through the
universe and on earth. This part describes how water circulates in the
environment. The book shows the various states it assumes when faced with heat
and cold and the temperature changes that make water into vapor, or its liquid
or solid form. The text shows that it can be sweet, brackish or salty and that
water is a sign that indicates the existence of life.
In the
second part the reader is invited to follow water in its movement, experiencing
the forms it takes and the various places it occupies in the heavens as hail, rain, or snowflakes, on earth, or
underground. The water cycle is described, in its forms as precipitation,
evaporation, soil infiltration, how it arises in springs and causes soil
erosion, as well as flooding and drought.
The third
part describes the path of water in the living bodies of humans, animals and
plants and highlights its role and importance to life. Water is in the sap that
carries mineral salts in the plants that exude water into the environment, in
the fluids of living bodies, such as tears, sweat, blood, urine, in the placental
fluid where babies live in their mother’s wombs, in cleansing of bodies while
batheing.
Since water
is a frequent theme in culture, religion and the arts, the fourth part of the
book shows how it is sung and spoken about and shown in various cultural and
artistic manifestations – music, poetry,
dance, urbanism and landscaping. In many spiritual traditions water is considered
sacred and used in purification rituals like Christian baptism and also mentioned
in biblical narratives like the great flood. In other traditions, there are water
gods and goddesses, and there are rituals like the rain dances of Indians. Many
words in all languages refer to water, and many places and cities have
water-related names.
In the
fifth and final part, the book highlights some of water’s multiple uses: for
human supply and for animals to drink, for irrigated agriculture, power
generation, transportation, as well as for fishing, recreation, leisure and
tourism. This final part shows everyone's need for water to maintain health and
well-being and denounces the waste that happens during its consumption. The
last part emphasizes the problems and insecurity arising from water scarcity or
excess in the cases of droughts and floods. It shows the importance of building
dams, canals, aqueducts, water and sewage treatment plants and of conserving
the soil to prevent leaching and silting and promoting protection of soil and water
sources. It underlines the importance of developing cooperation concerning
water and devising ways to promote dialogue and avoid rivalries, conflicts and
violence between those who need it and dispute possession of water.
A glossary
defines the main concepts used. Questions are formulated to enable the reader
to take a guided reading, the answers to which
help to better understand water and its multiple
uses.
