Scientific understanding of the process of extinction is insufficient to accurately make predictions about the impact of deforestation on biodiversity. [229] Most predictions of forestry related biodiversity loss are based on species-area models, with an underlying assumption that as the forest declines species diversity will decline similarly ...
The loss of biodiversity may not directly affect humans, but the indirect effects of losing many species as well as the diversity of ecosystems in general are enormous. When biodiversity is lost, the environment loses many species that perform valuable and unique roles in the ecosystem.
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, which can occur through the process of habitat fragmentation, is considered to be the greatest threat to species. [14] But, the effect of the configuration of habitat patches within the landscape, independent of the effect of the amount of habitat within the landscape (referred to as fragmentation per se [5]), has been suggested ...
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.
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.
"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.
Deforestation and biodiversity loss in the Amazon rainforest have resulted in significant risks of irreversible changes. Modeling studies have suggested that deforestation may be approaching a critical " tipping point " where large-scale " savannization " or desertification could occur, [ 71 ] leading to catastrophic consequences for the global ...
