Deforestation is the large-scale removal/clearing of forest cover, mainly for agriculture, logging, mining, and settlement. Its major consequences include:
- Loss of biodiversity — destruction of habitat leads to the loss of countless plant and animal species, many of which are found only in specific forest ecosystems.
- Soil erosion and degradation — tree roots that normally bind and hold the soil are removed, so topsoil is easily washed or blown away, ultimately leading to desertification of the land.
- Disruption of the water cycle — forests play an important role in the hydrological cycle through transpiration; their removal reduces local humidity and can alter and reduce regional rainfall patterns.
- Increased flooding — without the forest canopy and root systems to intercept and absorb rainwater, run-off increases sharply, leading to more frequent and severe floods, along with siltation of rivers and reservoirs. …
