Question

What is deforestation? Explain the causes and the consequences of deforestation.

Accepted Answer

Forests play an important role in the conservation of biodiversity. The cutting down the forest or clearing the forest land for wood or for the cultivation of crops is known as deforestation.

The causes of deforestation are:

Increase in population - Forest land is cleared to obtain this land.

Wood for industries (e.g., logging or wood harvest for domestic fuel or charcoal),

Construction of dams-natural vegetation is cut down for the purpose of building these dams.

Forest fires - Once the forest fire starts, it does not stop easily.

Infrastructure expansion such as road building and urbanisation.

The consequences of deforestation are:

Desertification - The removal of trees causes land degradation in dry-land that is not fertile and therefore the biological productivity decreases.

Soil erosion due to heavy rainfall or flood.

Groundwater loss.

Climate change and global warming occur due to deforestation because the plants maintain the temperature of the earth and the balance of gases in the atmosphere.

Imbalanced rainfall and water cycle.

Destruction of habitats of wild animals.
