Using land for agriculture and forestry can lead to soil erosion. Which of the following decreases with increased soil erosion?
A. Water turbidity
B. Biodiversity
C. Cases of respiratory disease
D. Desertification

All of them are correct soil erosion turns grains of soil into mere grains of sand which when placed in water makes the water much cloudier, biodiversity will decrease as soil erosion leads to a more Barron and dry landscape, respiratory disease may be caused by inhaled particles of dust which can be create from soil erosion, and desertification as mentioned earlier soil erosion leads to a more baron and dried out landscape as the soil can’t hold water as much as it used too.
