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.
During Destruction, Brahma Kumari leaders teach the world will be purified, all of the rest of humanity killed by nuclear or civil wars and natural disasters which will include the sinking of all other continents except India. [119] 1977 John Wroe: The founder of the Christian Israelite Church predicted this year for Armageddon to occur. [93]
Estimated time by which humanity could colonize the Milky Way galaxy and become capable of harnessing all the energy of the galaxy, assuming a velocity of 10% the speed of light. [177] 250,000 The estimated minimum time at which the spent plutonium stored at New Mexico's Waste Isolation Pilot Plant will cease to be radiologically lethal to ...
VHEMT was founded in 1991 by Les U. Knight, an American activist who became involved in the American environmental movement in the 1970s and thereafter concluded that human extinction was the best solution to the problems facing the Earth's biosphere and humanity.

This decline in plant life is likely to be a long-term decline rather than a sharp drop. Plant groups will likely die one by one well before the 50 parts per million level is reached. The first plants to disappear will be C 3 herbaceous plants, followed by deciduous forests, evergreen broad-leaf forests and finally evergreen conifers. [81]
Created by J. Robert Oppenheimer [citation needed] and maintained since 1947, the Clock is a metaphor, not a prediction, for threats to humanity from unchecked scientific and technological advances. That is, the time on the Clock is not to be interpreted as actual time.
An event that could cause human extinction or permanently and drastically curtail humanity's existence or potential is known as an "existential risk". [ 4 ] In the 21st century, a number of academic and non-profit organizations have been established to research global catastrophic and existential risks, formulate potential mitigation measures ...
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 ...
