"More than 99% of all species that ever
lived on Earth, amounting to over five billion species,
[1] are estimated to have died out.
[2][3][4][5]"
"In June 2019, one million species of plants and animals were at risk of extinction. At least 571 species have been lost since 1750, but likely many more. The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming.

"Human extinction is the hypothetical
end of the
human species due to either natural causes such as an
asteroid impact or
large-scale volcanism, or
anthropogenic (human) causes, also known as omnicide. For the latter, some of the
many possible contributors include
climate change,
global nuclear annihilation,
biological warfare and
ecological collapse. Other scenarios center on emerging technologies, such as
advanced artificial intelligence,
biotechnology, or
self-replicating nanobots. Scientists say there is relatively low risk of near term human extinction due to natural causes.
[2] The likelihood of human extinction through our own activities, however, is a current area of research and debate." (

"Survival sets a pretty low bar. The question isn’t so much whether humans survive the next three or three hundred thousand years, but whether we can do more than just survive." (
