>The event formerly called the Cretaceous-Tertiary or K–T extinction or K-T boundary is now officially named the Cretaceous–Paleogene (or K–Pg) extinction event. About 17% of all families, 50% of all genera[8] and 75% of all species became extinct.[9]
>(End Triassic): 201.3 Ma at the Triassic-Jurassic transition. About 23% of all families, 48% of all genera (20% of marine families and 55% of marine genera) and 70% to 75% of all species became extinct.[8]
>(End Permian): 252 Ma at the Permian-Triassic transition. Earth's largest extinction killed 57% of all families, 83% of all genera and 90% to 96% of all species[8] (53% of marine families, 84% of marine genera, about 96% of all marine species and an estimated 70% of land species,[2] including insects).[11]
>375–360 Ma near the Devonian-Carboniferous transition. At the end of the Frasnian Age in the later part(s) of the Devonian Period, a prolonged series of extinctions eliminated about 19% of all families, 50% of all genera[8] and at least 70% of all species.[14]
>(End Ordovician or O-S): 450–440 Ma at the Ordovician-Silurian transition. Two events occurred that killed off 27% of all families, 57% of all genera and 60% to 70% of all species.[8]

Life on earth has been bottlenecked quite a few times, it's crazy to think we're the result of a very specific strain of life having survived all five times.
Really now, I wonder when our next one is due.

>The ecology of humanity has been noted as being that of an unprecedented "global superpredator" that regularly preys on the adults of other apex predators and has worldwide effects on food webs. Extinctions of species have occurred on every land mass and ocean, with many famous examples within Africa, Asia, Europe, Australia, North and South America, and on smaller islands. Overall, the Holocene extinction can be characterized by the human impact on the environment.
Hundreds of millions of years of our planet trying to kill us has made us too good. We're literally breaking the system, we'll become a biologically-triggered Extinction Event ourselves unless we don't just break the system but learn how to play it.

The writing is on the wall
Aliens will make us extinct
Or our own technology
Buckle up
