You Wouldn't Want to Live Without Dirt!

ISBN: 978-0-531-22438-0

by Ian Graham

Without dirt—or soil—life would have developed differently and we humans probably wouldn't be here at all. Soil supplies a surprising variety of raw materials for making things. Learn about the ways soil has been used by humans over the centuries, from cave paintings to crop farming, and the exciting prospects for soil in the future.

Excerpts From Experts:

  • Some soil is formed by glaciers, slow-moving rivers of ice, as they grind up the rocks they travel across over thousands of years.
  • Never walk near the edge of a clifftop or the bottom of a cliff—the ground could suddenly give way and collapse.
  • The Tollund Man was preserved in waterlogged soil for 2,300 years.
  • Wash your hands after handling soil, because it can contain harmful bacteria.
