Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does not involve a reduction of the forest area, but rather a quality decrease in its condition."
Habitat degradation, fragmentation, and pollution are aspects of habitat destruction caused by humans that do not necessarily involve over destruction of habitat, yet result in habitat collapse. Desertification, deforestation, and coral reef degradation are specific types of habitat destruction for those areas (deserts, forests, coral reefs).
The degradation of forest ecosystems has also been traced to economic incentives that make forest conversion appear more profitable than forest conservation. [125] Many important forest functions have no markets, and hence, no economic value that is readily apparent to the forests' owners or the communities that rely on forests for their well ...
Biophysical mechanisms by which forests influence climate. Irreversible deforestation would result in a permanent rise in the global surface temperature. [23] Moreover, it suggests that standing tropical forests help cool the average global temperature by more than 1 °C or 1.8 °F.
Almost all of Europe's original forests have been destroyed. Scientists assert that human activity has pushed the earth into a sixth mass extinction event. [5] [6] The loss of biodiversity has been attributed in particular to human overpopulation, continued human population growth and overconsumption of natural resources by the world's wealthy.
In California, wildfires caused by humans grow faster and become hotter than wildfires sparked by lightning, the studies show.
Human-induced land degradation tends to be particularly serious in dry regions. Focusing on soil properties, Oldeman estimated that about 19 million square kilometers of global land area had been degraded; Dregne and Chou, who included degradation of vegetation cover as well as soil, estimated about 36 million square kilometers degraded in the ...
This has to end now, which is why MountainTrue has joined the Southern Environmental Law Center and the Chattooga Conservancy in challenging the Forest Service’s national, regional and unit ...
