Soil conservation is an important component of sustaining our way of life. All of our food is grown either in or on soils! Nevertheless, every year we lose thousands of acres of prime farm and grazing land to soil topsoil erosion, development, soil pollution and other factors. Watch this Youtube video to learn more about soil conservation in the United States.
A Culture of Conservation
Once you have watched the video, write a 4 to 5 paragraph essay reflecting on the following questions:
Observe the soils around where you live. What are the factors that influence soil erosion (both positive and negative) around you? Identify some of these soil erosion factors and describe whether they increase or decrease erosion.
Do you live in an area with abundant natural soils or in a city or town with little exposed soil? How will the quality of the soils in your area affect agricultural productivity, water quality and runoff, and the long-term sustainability of your region?
Soil erosion is agriculture`s enemy; a major environmental threat to sustainability and productivity with knock-on effects on the climate crisis and food security. This is particularly true for places with the highest risk of erosion, such as watershed in Indonesia, India, the Philippines and more. Soil erosion decreases soil fertility, which can negatively affect crop yields. Vegetation, rainfall, soil, and topography are the primary factors influencing soil erosion, although other factors may be involved. The kinetic impact of rain hitting the soil causes water erosion, and water erosion will occur when rainfall exceeds a certain value in a single rainfall event.
