    What are the consequences of deforestation?

    Answer:

    The consequences of deforestation-  Soil erosion-As the roots of trees hold soil together, once the trees are cut down soil gets washed away. Landslides- after deforestation, when there are no forest trees left to hold the soil as a result shear strength of soil particles decreases and landslides are more prone to occur. The level of oxygen and carbon dioxide in the atmosphere is disturbed. Trees act as natural air conditioners as they cool the earth by giving shade. So if we cut trees temperature rises. There is runoff from treeless slopes which carry soil and deposit them on river beds raising their levels. So during heavy rains, the water cannot be controlled and there are floods.
