Eroded sediment from farmland and dumping sites may contain pollutants or agrochemicals that may kill aquatic life if it reaches oceans, sea, eroded sediments may fill water reservoir constructed for HEP generation or. Losing these top layers of soils can also effectively introduce toxins and pesticides to nearby water sources along with other contaminants that were released when the soil was disturbed. Interactions between forest and landslide activity along new highways in the Kumaun Himalaya. For example, when the top layer of the soil, known as topsoil, moves from one place to another, it leads to soil erosion. Desertification can be characterized by the droughts and arid conditions the landscape endures as a result of human exploitation of fragile ecosystems. In addition to erosion, soil quality is affected by other aspects of agriculture. geography acsee Chen, Shiping, et al. csee necta questions Such negative impacts to aquatic ecosystems can also ultimately impact any .
