Overview

Excerpt from Our American Land: The Story of Its Abuse and Its Conservation Dense plant growth helps to slow down this soil movement. This gives nature time to replace what little soil is removed by erosion. Nature does this by constantly forming new topsoil from underlying subsoil and rock. This slow process, known as natural erosion or geologic erosion, goes on unnoticed over hundreds of years. This type is not dangerous usually; it may be beneficial to man and the earth. Many fine agricultural areas have been formed in this way. But where land is cultivated or left bare, another and faster kind of erosion occurs. This is accelerated erosion, and it is caused by man's carelessness. When land is cultivated there is no dense growth of plants to protect the soil, and erosion may be a thousand times faster than on protected land. Accelerated erosion damages grasslands when the grass is thinned out by overgrazing. It damages woodlands left bare by overcutting, overgrazing, and burning. This is what we now know as soil erosion, and unless it is checked, it may ruin most of our good land. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
