Earth's Mass Extinction

Earth has entered its sixth period of mass extinction - and humans could be among the casualties, scientists have warned

'Animals are dying out at 114 times the normal rate, triggered by a deadly mix of man made habitat loss, pollution and climate change, according to a study led by Stanford University in California'

'The authors say their analysis is 'extremely conservative' and the window of opportunity to prevent the worst species disaster since dinosaurs were swept from the planet 65 million years ago is 'rapidly closing'

Rock ape and his bum maggots dispute this, having put together a paper declaring they all be genius, and their worship and glorification of burnt Coal, reigns supreme in the knowledge of how our Earth's climate came about and how it is affected.

Sixth mass extinction: The era of 'biological annihilation'
Tue July 11, 2017 - Scientists have said it's clear that Earth is entering its sixth mass-extinction event; Study: A third of the 27,600 species are shrinking in terms of numbers and territorial range; "What is at stake is really the state of humanity," study author says

Many scientists say it's abundantly clear that Earth is entering its sixth mass-extinction event, meaning three-quarters of all species could disappear in the coming centuries. That's terrifying, especially since humans are contributing to this shift. But that's not even the full picture of the "biological annihilation" people are inflicting on the natural world, according to a study published Monday in the Proceedings of the National Academy of Sciences. Gerardo Ceballos, an ecology professor at the Universidad Nacional Autónoma de México, and his co-authors, including well-known Stanford University biologist Paul Ehrlich, cite striking new evidence that populations of species we thought were common are suffering in unseen ways. "What is at stake is really the state of humanity," Ceballos told CNN.

Their key findings: Nearly one-third of the 27,600 land-based mammal, bird, amphibian and reptile species studied are shrinking in terms of their numbers and territorial range. The researchers called that an "extremely high degree of population decay." The scientists also looked at a well-studied group of 177 mammal species and found that all of them had lost at least 30% of their territory between 1900 and 2015; more than 40% of those species "experienced severe population declines," meaning they lost at least 80% of their geographic range during that time.

Looking at the extinction crisis not only in terms of species that are on the brink but also those whose populations and ranges are shrinking helps show that "Earth's sixth mass extinction is more severe" than previously thought, the authors write. They say a major extinction event is "ongoing." "It's the most comprehensive study of this sort to date that I'm aware of," said Anthony Barnosky, executive director of the Jasper Ridge Biological Preserve at Stanford University, who was not involved in the study. Its value, Barnosky said, is that it makes visible a phenomenon typically unseen by scientists and the public: that even populations of relatively common species are crashing. "We've got this stuff going on that we can't really see because we're not constantly counting numbers of individuals," he said. "But when you realize that we've wiped out 50% of the Earth's wildlife in the last 40 years, it doesn't take complicated math to figure out that, if we keep cutting by half every 40 years, pretty soon there's going to be nothing left."

Stuart Pimm, chair of conservation ecology at Duke University in North Carolina, summed up the the concept this way: "When I look out over the woods that constitute my view from my window here, I know we no longer have wolves or panthers or black bears wandering around. We have eliminated a lot of species from a lot of areas. So we no longer have a functional set of species across large parts of the planet." This is an important point to emphasize, Pimm said. But the new paper's analysis risks overstating the degree to which extinction events already are occurring, he said, and the research methodology does not have the level of granularity needed to be particularly useful for conservationists. "What good mapping does is to tell you where you need to act," Pimm said. "The value of the Ceballos paper is a sense of the problem. But given there's a problem, what the bloody hell are we going to do about it?"

Maybe the Israelis have the technology that can save us..........
or at least significantly slow down the process?

Didn't have to be a genius to know that uncontrolled human population on a planet with finite resources has been the elephant in the room for the past 30 years, and everyone has been ignoring it. Won't take much for a water crisis to occur, then food riots happen, and human beings start messing their nappies.

Hmmm… Lets see
Population out of control, only getting bigger.
Less habitable land.
what do they eat,
Where do they sh-t
Nuke accidents making parts of the world uninhabitable.
Most of the larger fish, fished out.
Oceans turning into garbage dumps
religious groups bent on destroying each other, with WMD's.

Have a nice day.
