✅ The correct answer is option B.
Deforestation in the uplands may cause pollution in rivers through erosion and silting. Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth’s land surface, according to the World Wildlife Fund.
