    The correct answer is the last statement.


    Overgrazing by livestock results in soil erosion, which eventually causes sediments to run-off and get transported into an adjacent water body. This results in water turbidity. Overgrazing removes the grasses, thus, exposing the top cover soil to water erosion and wind.

    The withdrawal of the ground cover can also enhance drying, thus damaging the organic matter, and hampering the soil composition, which makes soil erosion to occur easily. Thus, overgrazing can hamper the composition of the soil, diminishing infiltration, and enhancing run-off.
