In particular, at 3.2 °C (5.8 °F), 15% of invertebrates (including 12% of pollinators), 11% of amphibians and 10% of flowering plants would be at a very high risk of extinction, while ~49% of insects, 44% of plants, and 26% of vertebrates would be at a high risk of extinction.
Humans are the main cause of the current mass extinction, called the Holocene extinction, driving extinctions to 100 to 1000 times the normal background rate. [ 120 ] [ 121 ] Though most experts agree that human beings have accelerated the rate of species extinction, some scholars have postulated without humans, the biodiversity of the Earth ...
When estimating the effect of climate change on species' extinction risk, the report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of the Earth's species with extinction even in the absence of any other factors like land use change. If the warming reached 4.3 °C (7.7 °F), they ...

The Voluntary Human Extinction Movement (VHEMT [A]) is an environmental movement that calls for all people to abstain from reproduction in order to cause the gradual voluntary extinction of humankind. VHEMT supports human extinction primarily because it would prevent environmental degradation.
Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction).
Rishi Sunak has said mitigating the risk of human extinction because of AI should be a global priority alongside pandemics and nuclear war.. AI will pose major security risks to the UK within two ...
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 ).
