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. Forest degradation is a type of the more general issue of land degradation.
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 ...
The Amazon rainforest has recently experienced fires that occurred inside the forest when wildfires tend to occur on the outer edges of the forest. [15] Wetlands have faced an increase in forest fires as well. [15] Due to the change in temperature, the climate around forests have become warm and dry, conditions that allow forest fires to occur ...
As an example, forest degradation may have a reference emission level for commercial selective logging and one for extraction of minor timber and firewood for subsistence use by rural communities. Effectively, every identified driver of deforestation or forest degradation has to be represented in one or more reference emission level(s).
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 forest resources of the United States remained relatively constant through the 20th century. [3] The Forest Service reported total forestation as 766,000,000 acres (3,100,000 km 2) in 2012. [4] [5] [3] A 2017 study estimated 3 percent loss of forest between 1992 and 2001. [6]
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
Habitat degradation is caused by the depletion of resources, in which human activities are the primary driving force. [ 48 ] [ 49 ] One major impact that the depletion of fish stocks causes is a dynamic change and erosion to marine food webs, which can ultimately lead to ecosystem collapse because of the imbalance created for other marine species.
