$\bullet$ Deforestation disturbs nature's balance by increasing the temperature and pollution level on Earth. It increases the level of carbon dioxide in the atmosphere. Groundwater level also gets lowered. If it continues, rainfall and the fertility of the soil will decrease eventually. Moreover, there will be increased chances of natural calamities such as floods and droughts.
$\bullet$ Deforestation is a major cause which leads to the change in soil properties. Physical properties of the soil get affected by plantation and vegetation. Fewer trees result in more soil erosion. Removal of the top layer of the soil exposes the lower, hard and rocky layers. This soil has less humus and is less fertile. Gradually the fertile land gets converted into deserts. It is called desertification.
$\bullet$ Deforestation also leads to a decrease in the water-holding capacity of the soil. The movement of water from the soil surface into the ground (infiltration rate) is reduced. So, there are floods. The other properties of the soil like nutrient content, texture, etc., are also affected by deforestation.
