Water issues touches every segment of our society and all economic sectors. Population growth,
rapid urbanization and industrialization, agriculture and tourism, climate change, all put water under
increasing stress. Given this growing pressure it is critical that this vital resource is properly
managed. However, water is not always just a source of life, it can often be destructive. Floods and
tsunamis can destroy cities and have already caused numerous human casualties. Therefore, it is
important to pay special attention to the water on Earth and ensure that it is not destroyed by
12 humans. This is the only way we can continue to use this resource without restrictions in the future.
THE AMOUNT OF WATER ON EARTH HASN’T CHANGED SINCE THE PLANET WAS FORMED
TWO BILLION YEARS AGO.
THE WATER THAT COMES FROM YOUR FAUCET COULD CONTAIN MOLECULES THAT
DINOSAURS AND NEANDERTHALS DRANK.
APPROXIMATELY 97% OF THE WATER ON EARTH IS SALT WATER. ONLY 3% IS FRESH
WATER. OF THAT 3%, MOST IS FROZEN IN THE POLAR CAPS OF ANTARCTICA. THE
REMAINING 1% IS FOR ALL HUMANITY'S NEEDS.
Possible questions: Where can you find water at home? Where can you find water at
school? Where can you find water in the city? Where can you find water in the
landscape?
As a teacher you can introduce and make an association with the Story of Creation. Tell
the children the story of how God create the world including the seas, rivers and lakes
which give us water. The children can discuss why we need water and what the world
would be like if God did not create the seas, rivers and lakes (there would be no fish, we wouldn’t
go swimming in the sea, there would be no boats).
