Wikipedia
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. Tropical rainforests is where the most concentrated deforestation occurs. About 30% of Earth's land surface is covered by forests.
In temperate mesic climates, natural regeneration of forest stands often will not occur in the absence of disturbance, whether natural or anthropogenic. Furthermore, biodiversity after regeneration harvest often mimics that found after natural disturbance, including biodiversity loss after naturally occurring rainforest destruction.
Deforestation occurs for multiple reasons: trees are cut down to be used or sold as fuel (sometimes in the form of charcoal) or timber, while cleared land is used as pasture for livestock and plantation. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforestation has also been used in war to deprive the enemy of cover for its forces and also vital resources. Modern examples of this were the use of Agent Orange by the British military in Malaya during the Malayan Emergency and the United States military in Vietnam during the Vietnam War. As of 2005, net deforestation rates have ceased to increase in countries with a per capita GDP of at least US$4,600. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland.
Disregard of ascribed value, lax forest management and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale. In many countries, deforestation, both naturally occurring and human induced, is an ongoing issue. Deforestation causes extinction, changes to climatic conditions, desertification, and displacement of populations as observed by current conditions and in the past through the fossil record. More than half of all plant and land animal species in the world live in tropical forests.
Between 2000 and 2012, of forests around the earth were cut down. As a result of deforestation, only remain of the original of forest that formerly covered the earth.
In the theory of programming languages in computer science, deforestation (also known as fusion) is a program transformation to eliminate tree structures.
The term "deforestation" was originally coined by Philip Wadler in his paper "Deforestation: transforming programs to eliminate trees".
Deforestation is typically applied to programs in functional programming languages, particularly non-strict programming languages such as Haskell. One particular algorithm for deforestation, shortcut deforestation, is implemented in the Glasgow Haskell Compiler.
Usage examples of "deforestation".
Overpopulation, over- development, nuclear terrorism, environmental warfare tactics, radiation leakage from power plants and waste dumps, toxic waste, air pollution, deforestation, pollution and overfishing of the oceans, global warming, ozone depletion, loss of biodiversity through extinction.
If all fossil fuels and their derivatives, as well as trees for paper and construction were banned in order to save the planet, reverse the Greenhouse Effect and stop deforestation.
Experts today conservatively estimate that, once fully restored in America, hemp industries will generate $500 billion to a trillion dollars per year, and will save the planet and civilization from fossil fuels and their derivatives - and from deforestation!
Fuel conversion was driven by both deforestation, and the opening of large new coal fields.
Like communalism and animism, non-nuclear family structures provide a poor defense against the corrosive effects of cities, where African culture is being redefined as deforestation tied to overpopulation drives peasants out of the countryside.
Deforestation, pollution, urbanization, had all progressed so far now that various points of no return had been passed.
It's perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential population growth.
