Biodiversity loss is in fact "one of the most critical manifestations of the Anthropocene" (since around the 1950s); the continued decline of biodiversity constitutes "an unprecedented threat" to the continued existence of human civilization. [61] The reduction is caused primarily by human impacts, particularly habitat destruction.
This type of biodiversity loss is known as one of the most critical threats to global biodiversity. The possible causes include habitat destruction and modification, diseases, exploitation, pollution, pesticide use, introduced species, and ultraviolet-B radiation (UV-B). However, many of the causes of amphibian declines are still poorly ...
Habitat loss is perhaps the greatest threat to organisms and biodiversity. [40] Temple (1986) found that 82% of endangered bird species were significantly threatened by habitat loss. Most amphibian species are also threatened by native habitat loss, [ 41 ] and some species are now only breeding in modified habitat. [ 42 ]
A 2019 UN report assessing global biodiversity extrapolated IUCN data to all species and estimated that 1 million species worldwide could face extinction. [ 38 ] [ 39 ] Conservation of a select species are often prioritized on several factors which include significant economic and ecological value, as well as desirability or attractiveness. [ 40 ]
Overexploitation is one of the main threats to global biodiversity. [3] Other threats include pollution, introduced and invasive species, habitat fragmentation, habitat destruction, [3] uncontrolled hybridization, [37] climate change, [38] ocean acidification [39] and the driver behind many of these, human overpopulation. [40]
Furthermore, habitat fragmentation is considered as an invasive threat to biodiversity, due to its implications of affecting large number of species than biological invasions, overexploitation, or pollution. [7]
According to the Report, the threat to species diversity is human-caused. [19] The main cause is the human land requirement, which deprives other species of their habitats. [ 10 ] In the past 50 years, the world's human population has doubled, [ 20 ] [ 12 ] per capita gross domestic product has quadrupled, [ 21 ] and biodiversity has suffered a ...
Many of the threats to biodiversity, including disease and climate change, are reaching inside borders of protected areas, leaving them 'not-so protected' (e.g. Yellowstone National Park). [180] Climate change , for example, is often cited as a serious threat in this regard, because there is a feedback loop between species extinction and the ...
