Cut away ¾ of the apple. This represents the percentage of the Earth’s surface covered by water.
Hold up ¼ of the apple.Half of this quarter is the desert.We can’t grow crops on desert.Cut the ¼ in half.
¾ of the remaining land is rocky. Cut the piece into quarters and dispose of the unusable rocky land.
The remaining piece is 1/32 of the original, 1/32 of the Earth’s surface.Trim off the peel.
Of this 1/32 this peel represents the precious inches of topsoil we have available on which to live and with which to feed our world population.
This topsoil supports virtually all plants and animals that live on land.
It filters water, serves as the basis for forests and other land ecosystems, and provides the medium and nutrients which make agriculture possible.
Questions • How can we keep topsoil from washing away? • How does it affect streams and waterways? • How does an increasing population affect topsoil? • How does this activity increase your awareness of the human-earth relationship?
Reflection • How is this activity “literacy”?
