Deforestation leads to

• It is the continuous cutting down of trees which leads to removal of forest, it is done for human needs like to obtain wood to make furniture, clearing space for laying new roads etc.
• Plants controls the effect of global warming, cutting down tree leads to vigorous climate changes and also decrease the water level of ground.
• Roots of plants hold onto the soil topmost fertile layer, cutting of trees will lead to soil erosion and soil quality will degrade and the soil become infertile.
• Forest is the habitat of many organisms, cutting forests will lead to the habitat loss and ultimately the biodiversity loss.
• Cutting down trees will lead to loss of resources we obtain from them (fruits, medicines).

Deforestation will lead to all, soil erosion, climate change, and reduction of forest product and biodiversity, so option D is the correct answer
