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.
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]
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 ...
Forest fragmentation is one of the greatest threats to biodiversity in forests, especially in the tropics. [70] The problem of habitat destruction that caused the fragmentation in the first place is compounded by: the inability of individual forest fragments to support viable populations, especially of large vertebrates
Deforestation of the Amazon rainforest is the most dramatic example of a massive, continuous ecosystem and a biodiversity hotspot being under the immediate threat from habitat destruction through logging, and the less-visible, yet ever-growing and persistent threat from climate change. [11] [12]
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]
Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. More than 99 percent of all species [ 1 ] that ever lived on Earth are estimated to be extinct .
