Deforestation is conversion of woodland areas to arable land, urban use, logged area or wasteland. Historically, this meant conversion to grassland or to its artificial counterpart, grainfields; however, the Industrial Revolution added urbanization. Generally this removal or destruction of significant areas of forest cover has resulted in a degraded environment with reduced biodiversity. In developing countries, massive deforestation is ongoing and is shaping climate and geography.
Deforestation (whether deliberate or unintended) is the result of the removal of trees without sufficient reforestation. There are many causes, ranging from extremely slow forest degradation to sudden and catastrophic wildfires. Deforestation can be the result of the deliberate removal of forest cover for agriculture or urban development, or it can be an unintentional consequence of uncontrolled grazing (which can prevent the natural regeneration of young trees). The combined effect of grazing and fires can be a major cause of deforestation in dry areas. In addition to the direct effects brought about by forest removal, indirect effects caused by edge effects and habitat fragmentation can greatly magnify the effects of deforestation.
While tropical rainforest deforestation has attracted most attention, tropical dry forests are being lost at a substantially higher rate, primarily as an outcome of slash-and-burn techniques used by shifting cultivators.

It means cutting trees. Deforestation is done to get rid of old trees to make the younger ones grow (reforestation). Nowadays, many people practice illegal deforestation which results to errosion.

Deforestation means that all trees in a given area have been removed.

deforestation means the destroying of forests.most of the factors which cause this are over grazing by animals ,growing population and need.......nature is also one of the factor....
