Deforestation causes many threats to wildlife as it not only causes habitat destruction for the many animals that survive in forests, as more than 80% of the world's species live in forests but also leads to further climate change. [8] Deforestation is a main concern in the tropical forests of the world.
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. Net change, therefore, can be positive or ...
Many [quantify] people value the complexity of the natural world and express concern at the loss of natural habitats and of animal or plant species worldwide. [ 53 ] Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services .
More than 140 countries made an ambitious pledge last year to halt forest loss. There's been progress, but not nearly enough.
The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]Defaunation is the global, local, or functional extinction of animal populations or species from ecological communities. [4]
Several studies since the early 1990s [30] have shown that large-scale deforestation north of 50°N leads to overall net global cooling [31] while tropical deforestation produces substantial warming. Carbon-centric metrics are inadequate because biophysical mechanisms other than CO 2 impacts are important, especially the much higher albedo of ...
Deforestation in Europe. France is the most deforested country in Europe, with only 15% of the native vegetation remaining. Deforestation in Bolivia, 2016. Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment , causing population fragmentation and ecosystem decay. [2]
An important consideration in such efforts is that forests can turn from sinks to carbon sources. [ 28 ] [ 29 ] [ 30 ] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [ 31 ] and deforestation .
