Nuclear war is an often-predicted cause of the extinction of humankind. [1]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), for example by sub-replacement fertility.
The population of early humans dwindled to around 1,280 individuals during a time of dramatic climate change and remained that small for about 117,000 years, the study said.
At current rates, about 30% of species are at risk of extinction in the next hundred years. [19] The Holocene extinction event is the result of habitat destruction, the widespread distribution of invasive species, poaching, and climate change. [20] [21] [22] In the present day, human activity has had a significant impact on the surface of the ...

Humans will soon go extinct unless we can find 5 more earths. We’re basically in the days of the dinosaurs, according to Stanford scientists.
[5] [6] The 2022 IPCC Sixth Assessment Report projects that human population would be in a range between 8.5 billion and 11 billion people by 2050. By the year 2100, the median population projection is at 11 billion people, while the maximum population projection is close to 16 billion people.

Assume, for simplicity, that the total number of humans who will ever be born is 60 billion (N 1), or 6,000 billion (N 2). [6]If there is no prior knowledge of the position that a currently living individual, X, has in the history of humanity, one may instead compute how many humans were born before X, and arrive at say 59,854,795,447, which would necessarily place X among the first 60 billion ...
