Detailed explanation-1: -Cutting down on trees leads to clearance of forests and so soil erosion occurs. Exposure of the soil to the sun’s heat dries up the moisture inside the soil. Nutrients evaporate and it affects the bacteria that help to break down organic matter. Due to this, rain washes the soil surfaces and erosion takes place.
Detailed explanation-2: -Deforestation means cutting of trees. When trees are cut, the soil becomes loose. When there is heavy rainfall or flood, the soil being loose is washed away and this leads to soil erosion.
Detailed explanation-3: -a) If we go on cutting trees: Rainfall and fertility of the soil will decrease. Changes in natural calamities will increase. It will also lead to a decrease in the water holding capacity of the soil which will result in floods.
Detailed explanation-4: -Without plant cover, erosion can occur and sweep the land into rivers. The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion.
