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 ...
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.
Citizen science, also known as public participation in scientific research, has been widely used in environmental sciences and is particularly popular in a biodiversity-related context. It has been used to enable scientists to involve the general public in biodiversity research, thereby enabling the scientists to collect data that they would ...
Carbon emissions from tropical deforestation are accelerating. [7] [8] When forests grow they are a carbon sink and therefore have potential to mitigate the effects of climate change. Some of the effects of climate change, such as more wildfires, [9] invasive species, and more extreme weather events can lead to more forest loss.
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.
[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. [ 7 ] [ 8 ] A 2020 report by the World Wildlife Fund found that human activity – specifically overconsumption, population growth and intensive farming ...
Summary of major biodiversity-related environmental-change categories expressed as a percentage of human-driven change (in red) relative to baseline (blue) It has been estimated that from 1970 to 2016, 68% of the world's wildlife has been destroyed due to human activity. [132] [133] In South America, there is believed to be a 70 percent loss. [134]
The loss and fragmentation of habitats makes it difficult for migratory species to find places to rest and feed along their migration routes. [24] The effects of current fragmentation will continue to emerge for decades. Extinction debts are likely to come due, although the counteracting immigration debts may never fully be paid.
