Per capita CO 2 emissions from deforestation for food production Illegal "slash-and-burn" practice in Madagascar, 2010 Mean annual carbon loss from tropical deforestation. [149] Deforestation is a major contributor to climate change. [150] [151] [152] It is often cited as one of the major causes of the enhanced greenhouse effect.
Biodiversity loss happens when plant or animal species disappear completely from Earth or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4] [5] Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon.
Habitat loss is perhaps the greatest threat to organisms and biodiversity. [40] Temple (1986) found that 82% of endangered bird species were significantly threatened by habitat loss. Most amphibian species are also threatened by native habitat loss, [ 41 ] and some species are now only breeding in modified habitat. [ 42 ]
The loss and fragmentation of habitats makes it difficult for migratory species to find places to rest and feed along their migration routes. [24] The effects of current fragmentation will continue to emerge for decades. Extinction debts are likely to come due, although the counteracting immigration debts may never fully be paid.
As the need for new agricultural areas and road construction increases, the deforestation processes stay in effect. Deforestation is the "removal of forest or stand of trees from land that is converted to non-forest use." (Wikipedia-Deforestation). Since the 1960s, nearly 50% of tropical forests have been destroyed, but this process is not ...
The results suggested that higher levels of fragmentation within the fish-bone pattern led to the loss of species and decreased diversity of large vertebrates. [27] Human impacts, such as the fragmentation of forests, may cause large areas to lose the ability to maintain biodiversity and ecosystem function due to loss of key ecological ...
Forest loss is acute in Southeast Asia, [42] the second of the world's great biodiversity hot spots. [43] According to a 2005 report conducted by the FAO, Vietnam has the second highest rate of deforestation of primary forests in the world, second to only Nigeria . [ 44 ]
