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.
Currently, livestock make up 60% of the biomass of all mammals on earth, followed by humans (36%) and wild mammals (4%). [29] According to the 2019 global biodiversity assessment by IPBES, human civilization has pushed one million species of plants and animals to the brink of extinction, with many of these projected to vanish over the next few ...
Humans [3] Quaternary extinction event: 640,000, 74,000, and 13,000 years ago: Unknown; may include climate changes, massive volcanic eruptions and Humans (largely by human overhunting) [4] [5] [6] Neogene: Pliocene–Pleistocene boundary extinction: 2 Ma: Possible causes include a supernova [7] [8] or the Eltanin impact [9] [10] Middle Miocene ...
Many [quantify] people value the complexity of the natural world and express concern at the loss of natural habitats and of animal or plant species worldwide. [53] Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services.
Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Most scholars think that the project peak global world population of between 9-10 billion people, could live sustainably within the earth's ecosystems if human society worked to live sustainably within planetary ...
Earth has already warmed 2.3 degrees Fahrenheit since the preindustrial era and is on track to heat up a total of 4.7 to 5.6 degrees. That ensures more deadly and destructive heat waves, storms ...
He claims that even though mammals (such as humans) can have relatively long lifespans, we still operate under dinosaur-era restraints. Mammals may struggle to attain long life thanks to dinosaurs.
The report warned that the pollution crisis was exceeding "the envelope on the amount of pollution the Earth can carry" and "threatens the continuing survival of human societies". [34] Carl Sagan and others have raised the prospect of extreme runaway global warming turning Earth into an uninhabitable Venus-like planet.
