Detailed explanation-1: -Deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction. Deforestation has greatly altered landscapes around the world.

Detailed explanation-2: -Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate.

Detailed explanation-3: -Selection cutting (ecoforestry) – removing selected trees for different purposes (harvesting, ecological, forest health, etc.). Commercial logging usually implies the removal of the most expensive timber. Slash-and-burn – cutting and burning forests with further use for agriculture or construction.

Detailed explanation-4: -Forest conversion is the clearing of natural forests (deforestation) to use the land for another purpose, often agricultural (growing crops like palm oil or creating pasture for cattle), but also for mines, infrastructure or urbanisation. Forest conversion is the largest cause of global deforestation today.
