Deforestation removes the forest cover that holds ecosystems, soil and the water cycle together, so its major consequences include biodiversity loss, soil erosion/desertification, and disturbance of local climate and rainfall.

Deforestation — the large-scale clearing of forests for timber, agriculture, mining or human settlement — has several serious environmental consequences, of which any two may be cited:

  1. Loss of biodiversity: Forests are home to the majority of the world's terrestrial plant and animal species. Clearing forest destroys their habitat, driving species to local extinction and drastically reducing biodiversity.
  2. Soil erosion and desertification: Tree roots bind the soil and reduce surface run-off. Without forest cover, topsoil is rapidly washed or blown away, degrading soil fertility and, over time, converting once-forested land into desert-like, unproductive land.
  3. Disruption of the water cycle/local climate: Trees contribute substantially to transpiration and local rainfall generation; deforestation reduces local rainfall, lowers groundwater recharge, and increases the risk of both drought and flash flooding. …
