Study warns that humans may be driving Earth toward a sixth mass extinction. The research shows species loss, but the future ...

"The pace of change we’re seeing today is unlike anything we know of in the past 66 million years," said ecologist Jack Hatfield.

Scientists debate whether current extinction rates mark a planet-wide crisis or reflect a more nuanced reality, highlighting the challenges of defining and measuring human impact on biodiversity.

Human activity may be triggering the greatest extinction event since the asteroid impact that wiped out the dinosaurs, ...

The narrative of life on Earth is marked by a continual ebb and flow, characterized by the emergence and extinction of countless species over time. Extinction, an inherent aspect of the evolutionary ...

(CNN) — Humans have wiped out hundreds of species — with many more on the brink or experiencing large declines in population. Some scientists have argued that we have entered a “sixth mass extinction” ...

We're in the midst of the Earth’s sixth mass extinction crisis. Harvard biologist E. O. Wilson estimated that 30,000 species per year (or three species per hour) are being driven to extinction.

Our planet’s first known mass extinction happened about 440 million years ago. Species diversity on Earth had been increasing over a period of roughly 30 million years, but that would come to a halt ...

Scientists warn that the planet is entering its sixth mass extinction, a crisis driven by deforestation, pollution, and the rapid disappearance of species at rates unseen since the age of dinosaurs.
