One of our most important natural resources is soil. This resource is often overlooked by students and teachers interested in environmental issues. Professional conservationists, however, recognize the importance of soil in natural resource management and the interrelationships between soil, water, and other resources. Soil provides a growth medium for all plant life on our planet, including food and energy resources. Soil also provides habitat, filters water, and is used in constructing buildings.
