Amazon.com Product Description (ISBN 0531214885, Library Binding)What if we didnt have any dirt or soil? Its hard to imagine. The ground would look different and many of the plants, trees and animals we know today would disappear. Dirt, and or soil, supplies a surprising variety of raw materials for making things. Learn about the ways dirt and soil have been used by humans over the centuries, from cave paintings to crop farming, and the exciting prospects for dirt and soil we may see in the future.
