EUROPE: The world is embarking on its sixth mass extinction with animals disappearing about 100 times faster than they used to, scientists warn, and humans could be among the first victims of the next extinction event.
Not since the age of the dinosaurs ended 66 million years ago has the planet been losing species at this rapid a rate, a study led by experts at Stanford University, Princeton University and the University of California, Berkeley said.
The study “shows without any significant doubt that we are now entering the sixth great mass extinction event,” co-author and Stanford University professor of biology Paul Ehrlich said.
And the study, which was published in the journal Science Advances on Friday and described by its authors as “conservative”, said humans were likely to be among the species lost.
“If it is allowed to continue, life would take many millions of years to recover and our species itself would likely disappear early on,” lead author Gerardo Ceballos of the Universidad Autonoma de Mexico said.
The analysis was based on documented extinctions of vertebrates, or animals with internal skeletons such as frogs, reptiles and tigers, from fossil records and other historical data.
The modern rate of species loss was compared to the “natural rates of species disappearance before human activity dominated”.
It can be difficult to estimate this rate, also known as the background rate, since humans do not know exactly what happened throughout the course of Earth’s 4.5 billion year history.
