You may not consider this material soil, just a large pile of sand; however, soil is the natural medium for the growth of land plants (note plants on the steep slopes), whether or not it has discernible soil horizons.
People consider soil important because it supports plants that supply food, fibers, drugs, and other human needs and because it filters water and recycles wastes. For purposes of classification, the lower boundary of soil is arbitrarily set at 200 cm. All terrestrial life ultimately depends on soil, energy, and water. Soils have always been central to human civilization and life. They are an integral part of the physical and cultural environment, and we may take them for granted and even tend to treat them contemptuously.
