What is Deforestation? What are the cause of Deforestation?
Answers
when forests are cut down on a large scale it is called deforestation.
the deforestation is done for urbanization and industrialization
it means for making ,factories industries road
please can u mark me brainliest
Answer:
The removal of trees without sufficient reforestation has resulted in habitat damage, biodiversity loss, and aridity. 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.[11] Deforestation also has adverse impacts on biosequestration of atmospheric carbon dioxide, increasing negative feedback cycles contributing to global warming. Global warming also puts increased pressure on communities who seek food security by clearing forests for agricultural use and reducing arable land more generally. Deforested regions typically incur significant other environmental effects such as adverse soil erosion and degradation into wasteland. According to a study published in Nature Scientific Reports if deforestation continue in current rate in the next 20 – 40 years, it can trigger a full or almost full extinction of humanity. To avoid it humanity should pass from a civilization dominated by the economy to "cultural society" that "privileges the interest of the ecosystem above the individual interest of its components, but eventually in accordance with the overall communal interest"[12]
Deforestation is more extreme in tropical and subtropical forests in emerging economies. More than half of all plant and land animal species in the world live in tropical forests.[13] As a result of deforestation, only 6.2 million square kilometres (2.4 million square miles) remain of the original 16 million square kilometres (6 million square miles) of tropical rainforest that formerly covered the Earth.[10] An area the size of a football pitch is cleared from the Amazon rainforest every minute, with 136 million acres (55 million hectares) of rainforest cleared for animal agriculture overall.[14] More than 3.6 million hectares of virgin tropical forest was lost in 2018.[15] Consumption and production of beef is the primary driver of deforestation in the Amazon, with around 80% of all converted land being used to rear cattle.[16][17] 91% of Amazon land deforested since 1970 has been converted to cattle ranching.[18][19] The global annual net loss of trees is estimated to be approximately 10 billion.[20][21] According to the Global Forest Resources Assessment 2020 the global average annual deforested land in the 2015–2020 demi-decade was 10 million hectares and the average annual forest area net loss in the 2000–2010 decade was 4.7 million hectares.[6] The world has lost 178 million ha of forest since 1990, which is an area about the size of Libya.[6]
Explanation:
According to the United Nations Framework Convention on Climate Change (UNFCCC) secretariat, the overwhelming direct cause of deforestation is agriculture. Subsistence farming is responsible for 48% of deforestation; commercial agriculture is responsible for 32%; logging is responsible for 14%, and fuel wood removals make up 5%.[22]
Experts do not agree on whether industrial logging is an important contributor to global deforestation.[23][24] Some argue that poor people are more likely to clear forest because they have no alternatives, others that the poor lack the ability to pay for the materials and labour needed to clear forest.[23] One study found that population increases due to high fertility rates were a primary driver of tropical deforestation in only 8% of cases.[25]
Other causes of contemporary deforestation may include corruption of government institutions,[26][27] the inequitable distribution of wealth and power,[28] population growth[29] and overpopulation,[30][31] and urbanization.[32] Globalization is often viewed as another root cause of deforestation,[33][34] though there are cases in which the impacts of globalization (new flows of labor, capital, commodities, and ideas) have promoted localized forest recovery.[35]
Another cause of deforestation is climate change. 23% of tree cover losses result from wildfires and climate change increase their frequency and power.[36] The rising temperatures cause massive wildfires especially in the Boreal forests. One possible effect is the change of the forest composition.[37]
