What is the definition of deforestation?

Deforestation is defined as the clearing of forested areas, particularly through the removal of trees and other vegetation. This process is often conducted to convert land for agricultural use, urban development, or other human activities. The main characteristic of deforestation is that it results in a significant reduction in forest cover, which can lead to negative environmental impacts such as loss of biodiversity, disruption of water cycles, and increased greenhouse gas emissions.

The other options reflect conservation practices or activities aimed at enhancing forest areas rather than the act of removing trees. Conservation of natural forest areas focuses on protecting existing forests instead of clearing them. Planting new trees involves reforestation efforts that aim to increase tree cover rather than eliminate it. Restoring natural landscapes typically refers to efforts made to rehabilitate and restore ecosystems that have been degraded, again moving away from the concept of deforestation.
