Earth Almost Ended 5 Times — Are We Entering a Sixth Mass Extinction?

Earth has survived five extraordinary mass extinction events.

The Ordovician extinction brought severe glaciation and falling sea levels.

The Devonian extinction unfolded alongside major environmental changes and widespread ocean oxygen loss.

The Permian extinction—the Great Dying—was the most devastating, with enormous Siberian volcanism associated with catastrophic climate and ocean changes.

The Triassic extinction followed another period of massive volcanism and environmental disruption.

Then, 66 million years ago, an asteroid struck what is now Mexico and helped bring about the extinction of the non-avian dinosaurs.

Now humanity is driving unprecedented pressures on biodiversity through habitat destruction, pollution, overexploitation and climate change.

Scientists are debating whether this could represent the beginning of a sixth mass extinction.

And there's a new factor: artificial intelligence.

AI could become a powerful tool for conservation and scientific research. But it could also amplify humanity's ability to transform the planet.

The future isn't predetermined.

The question is what we choose to build next.
