Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction 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.
MacDiarmid was last seen late on the night of 11 July 1990, in the parking lot of Kananook railway station. Evidence found near her car suggested a struggle, and foul play is suspected. Police have interviewed two potential suspects, but she officially remains missing. [20][21] 15 August 1990. Eugene John Hebert. 66.
Published estimates for the 1st century (" AD 1 ") suggest uncertainty of the order of 50% (estimates range between 150 and 330 million). Some estimates extend their timeline into deep prehistory, to " 10,000 BC", i.e., the early Holocene, when world population estimates range roughly between 1 and 10 million (with an uncertainty of up to an ...
March 16, 2010. (2010-03-16) Life After People is a television series on which scientists, mechanical engineers, and other experts speculate about what might become of planet Earth if humanity suddenly disappeared. The featured experts also talk about the impact of human absence on the environment and the vestiges of civilization thus left behind.
The world's populationis over 8 billion[38]and Earth's total surface area (including land and water) is 510 million square kilometres (197 million square miles).[39] Therefore, the worldwide human population density is 8 billion ÷ 510 million km2(197 million sq mi) = 15.7 people/km2(41 people/sq mi).

The largest extinction was the Kellwasser Event (Frasnian - Famennian, or F-F, 372 Ma), an extinction event at the end of the Frasnian, about midway through the Late Devonian. This extinction annihilated coral reefs and numerous tropical benthic (seabed-living) animals such as jawless fish, brachiopods, and trilobites.
[103] [104] By 2000, there were approximately ten times as many people on Earth as there had been in 1700. However, this rapid growth did not last. During the period 2000–2005, the United Nations estimates that the world's population was growing at an annual rate of 1.3% (equivalent to around 80 million people), down from a peak of 2.1% ...
