Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use.More than half of the animal and plant species in the world live in tropical forests.
Deforestation is ongoing and is shaping climate and geography.
Deforestation is a contributor to global warming and is often cited as one of the major causes of the enhanced greenhouse effect. Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions.
The water cycle is also affected by deforestation. Trees extract groundwater through their roots and release it into the atmosphere. When part of a forest is removed, the trees no longer transpire this water, resulting in a much drier climate. Deforestation reduces the content of water in the soil and groundwater as well as atmospheric moisture. The dry soil leads to lower water intake for the trees to extract.
Undisturbed forests have a very low rate of soil loss, approximately 2 metric tons per square kilometer (6 short tons per square mile).Deforestation generally increases rates of soil erosion, by increasing the amount of runoff and reducing the protection of the soil from tree litter. This can be an advantage in excessively leached tropical rain forest soils.
Deforestation on a human scale results in decline in biodiversity,and on a natural global scale is known to cause the extinction of many species.The removal or destruction of areas of forest cover has resulted in a degraded environment with reduced biodiversity.Forests support biodiversity, providing habitat for wildlife; moreover, forests foster medicinal conservation.
More Trees ;More Life
I can not only live but also talk!!!
I want to live with my friends in the forest,
