Name: Lauren. 144 62 Date: 3-29- 23 Soil Erosion and Feedback Due : Key Question: How does overexploitation of Earth's natural systems cause the disruption of those systems? Soil and water loss Soil is important for plant growth. Soil contains various minerals and materials that help it to retain water and remain bound together. Loss of vegetation can reduce the water in soil by increasing water runoff and the effect of wind action. This, in turn, further reduces vegetation growth. This positive feedback can quickly cause land to become unproductive, especially in harsh environments such as the semi-arid rangelands of the south and mid-western United States. Here, overgrazing by livestock removes plant cover and increases evaporation from exposed soils. Rangelands can quickly be turned into dry, sandy deserts as the soils dry out and plant growth is reduced. vasn Livestock eats Decreased Increased vegetation cover plant cover evaporation from exposed soils Increased exposure to wind Reduced water Increased water Increased surface erosion infiltration rate runoff Reduced water Decreased Decreased plant Loss of soil retention in soil litter cover production Vegetated Vegetated roded USDA The Dust Bowl in the 1930s was a result Overgrazing has detrimental effects Erosion of soil in forests can result from of drought and the removal of vegetation. on grasslands, opening space for deforestation.
