Forest area net change rate per country in 2020. Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period ...
Deforestation is a primary contributor to climate change, [1] [2] and climate change affects the health of forests. [3] 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 .
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 ]
Moreover, fragmentation can change the microclimate at both local and regional scales, influencing biodiversity through interactions with anthropogenic climate change. [63] Overall, habitat fragmentation significantly disrupts ecosystem services by altering nutrient retention, biodiversity, and ecosystem functioning at various spatial and ...
For now, deforestation of the Amazon rainforest has been the greatest threat to it, and the main reason why, as of 2022, about 20% of it had been deforested and another 6% "highly degraded". [95] Yet, climate change is also a threat as it exacerbates wildfire and interferes with precipitation.
"This does not involve a reduction of the forest area, but rather a quality decrease in its condition." The forest is still there, but with fewer trees, or fewer species of trees, plants or animals, or some of them affected by plagues. [1] This degradation makes the forest less valuable and may lead to deforestation.
These regions contain a high number of plant and animal species and have been subjected to high levels of habitat destruction by human activity, leading to biodiversity loss. Deforestation and increased road-building in the Amazon Rainforest in Bolivia cause significant concern because of increased human encroachment upon wild areas, increased ...
25-50% of the rainfall in the Amazon basin comes from the forest, and if deforestation reaches 30-40% most of the Amazon basin will enter a permanent dry climate. [14] In another article published by Nature, it points out that tropical deforestation can lead to large reductions in observed precipitation. [15]
