Researchers from several universities have released a study that concludes the Earth has entered into its sixth mass extinction. Rob Jordan author of the Stanford Woods Institute for the Environment states, “There is no longer any doubt: We are entering a mass extinction that threatens humanity’s existence.”
The onset of the extinction is due to human activity. Paul Ehrlich, the Bing Professor of Population Studies in biology and a senior fellow at the Stanford Woods Institute for the Environment, calls for “fast action to conserve threatened species, populations and habitat, but warn that the window of opportunity is rapidly closing.”
“The study shows without any significant doubt that we are now entering the sixth great mass extinction event,” Ehrlich said. “There are examples of species all over the world that are essentially the walking dead. We are sawing off the limb that we are sitting on.”
The study shows that “even with extremely conservative estimates, species are disappearing up to about 100 times faster than the normal rate between mass extinctions.”
“If it is allowed to continue, life would take many millions of years to recover, and our species itself would likely disappear early on,” said lead author Gerardo Ceballos of the Universidad Autónoma de México.
“We are now entering the sixth great mass extinction event,” one of the authors of the paper told the BBC.
Gerardo Ceballos, lead author of the research, added: “If it is allowed to continue, life would take many millions of years to recover and our species itself would likely disappear early on”.
The main causes of the mass extinction are:
- Land clearing for farming, logging and settlement
- Introduction of invasive species
- Carbon emissions that drive climate change and ocean acidification
- Toxins that alter and poison ecosystems
