Despite the strong empirical evidence and highly visible collapse-inducing disturbances, anticipating collapse is a complex problem. The collapse can happen when the ecosystem's distribution decreases below a minimal sustainable size, or when key biotic processes and features disappear due to environmental degradation or disruption of biotic ...
Such pressures on wild species can be alleviated through wildlife conservation efforts, such as the establishment of protected areas. From 1996 to 2008, conservation efforts in 109 countries reduced the extinction risk of their wild mammals and birds by 29%, while conservation action throughout 2010s lowered the average extinction risk of birds ...
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
In March 2019 Chris D. Thomas and other scientists wrote in response to the apocalyptic "Insectageddon" predictions of Sánchez-Bayo, "we respectfully suggest that accounts of the demise of insects may be slightly exaggerated". They called for "joined-up thinking" in responding to insect declines, backed up by more robust data than were ...
The collapse of the northern cod fishery marked a profound change in the ecological, economic and socio-cultural structure of Atlantic Canada. The moratorium in 1992 was the largest industrial closure in Canadian history, [ 23 ] and it was expressed most acutely in Newfoundland, whose continental shelf lay under the region most heavily fished.
In response to Ehrlich's assertion that all major marine wildlife would die by 1980, Ronald Bailey termed Ehrlich an "irrepressible doomster". [10] Ehrlich has acknowledged that "some" of what he predicted has not occurred, but nevertheless maintains that his predictions about disease and climate change were essentially correct and that human ...

Relative to now, key areas for wildlife will retain less of their biodiversity under 2 °C (3.6 °F) of global warming, and even less under 4.5 °C (8.1 °F). [35] The first major attempt to estimate the impact of climate change on generalized species' extinction risks was published in the journal Nature in 2004.
