Erosion is regarded not merely as the physical removal of soil by water and wind,
but rather as the deterioration of all the component parts of the habitat in which
man and his crops and livestock have to exist. Since there is no conclusive
evidence for any major climatic change in historic times to explain this
deterioration, we must conclude that the eroding of the total environment has been
due primarily to thoughtless destruction of the vegetative cover. This has led to
deterioration of the microclimate above and below the surface, generally in the
direction of a general drying out of the soil which has exposed it to erosive action
of wind and rainfall of high intensity or frequency, and to the loss of organic matter
in the soil, thus reducing its capacity to resist erosion by conserving the water that
falls on the surface. If everything possible is done within the total environment to
conserve the naturally planted or cultivated vegetation, this will also ensure
optimal conservation of soil and water.
