Asteroid impacts: one large impact is associated with a mass extinction, that is, the Cretaceous–Paleogene extinction event; there have been many smaller impacts but they are not associated with significant extinctions, [105] or cannot be dated precisely enough.
The most famous of these mass extinction events — when an asteroid slammed into Earth 66 million years ago, dooming the dinosaurs and many other species — is also the most recent. But ...
The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes. Researchers have identified five other major extinction events in Earth's history, with estimated losses below: [11] End Ordovician: 440 million years ago, 86% of all species lost, including graptolites
There is a 1% chance every billion years that a star will pass within 100 AU of the Sun, potentially disrupting the Solar System. [29] The mean time for the Sun to collide with another star in the solar neighborhood is approximately 30 trillion ( 3 × 10 13 ) years, which is much longer than the estimated age of the Universe, at approximately ...
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). Some of the many possible contributors to anthropogenic hazard are climate change, global nuclear ...
Here are 10 of the most devastating animal extinctions in recent history, plus a closer look at the dire impact of human greed and why we need stronger wildlife protection measures.
