Soil is the earth’s fragile skin that anchors all life on Earth. It is comprised of countless species and microorganisms that create a dynamic and complex ecosystem and is among the most precious resources to humans. But half of the topsoil on the planet has been lost in the last 150 years. Many factors are echoing to portend soil erosion, the problem that has wide range of effects that are surprising to us. Soil erosion can be caused naturally or by wind and water. But human activity is a true cause of erosion and it has surpassed its natural counterpart. The quick population growth increases higher demand to turn forest to farmland, field and pasture in order to produce enough foods. The transition to agriculture from natural vegetation requires cutting down a lot of trees. Furthermore, the repeated planting method, burning field, and chemical using performed by farmers can lead to the losing of soil structure and soil nutrient degradation. These are only some of the many other causes of soil erosion. The problem is common worldwide and it can cost more than what we ever think about. The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding. Sustainable land use can help to reduce the impacts of agriculture and livestock, preventing soil degradation and erosion and the loss of valuable land to desertification. The health of soil is a primary concern as our food supplies are rooted into it. Change need to be implemented in order to make our agricultural activities become more soil health friendly.
