The correct option is D All of these
In the given figure, a man is cutting down trees. Deforestation is the clearance or clearing of a forest or a group of trees. When a large number of trees are cut, the carbon dioxide level increases and oxygen level decreases as plants take in CO2 and release oxygen in the process of photosynthesis. Trees also serve as a habitat for a variety of animals and birds. Due to deforestation, the land becomes barren and leads to soil erosion during heavy rains resulting in loss of soil fertility.
