And the rapid rate of extinctions isn't even unprecedented; as I pointed out, the end-Cretaceous event was far faster.
That does not change the fact that the current extinction event is comparable to these five others.
And I pointed out that the extremely rapid rate of extinction for the end of the Cretaceous era was because the cause of the extinction was a massive singular event.
Because we're a bunch of fuckups, that's why.
No, seriously. Human civilisation is doomed. It is unsustainable because of the resource depletion and climate change which it inevitably triggers. The good news is that the collapse of our civilisation will likely save the rest of the planet from the worst of our fuckery. We can't even cause a proper extinction event. Lol.
Even at a worst case scenario in terms of emissions, we will definitely last until the next century. At that date, about half of all plant and animal species will be gone.
And at that point, even if we started a civilisational collapse, the legacy of our pollution would continue the negative impacts, so the extinction rate would continue and could even accelerate.
