What is Deforestation?
Deforestation means clearing of forests and using that land for other purposes. Trees in the forest are cut for some of the purposes mentioned below:
a. Procuring land for cultivation

c. Making furniture or using wood as fuel
Consequences of Deforestation
There are certain consequences of deforestation. They are listed as follows:
It increases the temperature and pollution level on the Earth
It increases the level of carbon dioxide in the atmosphere
Groundwater level gets lowered
Rainfall and fertility of the soil decreases
Chances of occurrence of natural calamities such as floods & droughts increases
Cutting down trees will increase the level of carbon dioxide in the atmosphere. This leads to global warming as carbon dioxide traps the heat rays reflected by the earth.
Reduces water holding capacity of the soil
Makes the soil infertile
What is Desertification?
Deforestation leads to a change in the soil properties. Soil gets eroded because of wind and heavy rain which leads to the loss of the topmost fertile layer of the soil. Removal of the fertile layer exposes the lower, hard, and rocky layer. Gradually, the fertile land gets converted into deserts. This is termed as desertification.
