Loss of topsoil due to over farming can lead to increased sedimentation in nearby river streams. This can result in murky and cloudy water, decreased water quality, and disruption of aquatic ecosystems. Additionally, the sediment can also carry pollutants, such as agricultural chemicals and fertilizers, into the river streams, further degrading water quality and harming aquatic life. Over time, these impacts can lead to decreased biodiversity, decreased fish populations, and overall degradation of the river stream ecosystem.
