6th Mass Extinction

Earth’s Sixth Mass Extinction Is Here

Stanford University study, shows humans have triggered sixth mass extinction of Earth’s species

Not since the vanishing of dinosaurs 65 millions years ago has the Earth seen such mass extinction of species, and in as little as two or three lifetimes, “huge amounts” of biodiversity will be lost forever, researchers predict. Because each species plays a specific role within the Earth’s ecosystem, such major loss may take the Earth millions of years to recover, say researchers.

“Our activities are causing a massive loss of species that has no precedent in the history of humanity and few precedents in the history of life on Earth,” said lead researcher Gerardo Ceballos, a professor of conservation ecology at the National Autonomous University of Mexico and a visiting professor at Stanford University.

Today’s CO2 levels(400ppm) are now approaching that of the mid-Miocene period(405ppm) 15 million years ago when sea level was 25–40 meters higher and global mean temperatures were 3­–6°C hotter. And we’re still throwing fuel on the fire at a rate of change that is 100 times faster than at any time in the last 65 million years. Humans will be the first sentient beings to have documented their own demise while arguing with each over over the scientific data and whether it was really their fault.

As climate science has evolved in the last half century, we have learned that the earth is much more sensitive to abrupt climate events which can occur in as little as one year with a spike in temperature of up to 10°C.

“Swings of temperature that in the 1950s scientists had believed would take tens of thousands of years, in the 1970s thousands of years, and in the 1980s hundreds of years, were now found to take only decades. Ice core analysis by Dansgaard’s group, confirmed by the Americans’ parallel hole, showed rapid oscillations of temperature repeatedly at irregular intervals throughout the last glacial period. Greenland had sometimes warmed a shocking 7°C within a span of less than 50 years. For one group of American scientists on the ice in Greenland, the “moment of truth” struck on a single day in midsummer 1992 as they analyzed a cylinder of ice, recently emerged from the drill hole, that came from the last years of the Younger Dryas. They saw an obvious change in the ice, visible within three snow layers, that is, scarcely three years! The team analyzing the ice was first excited, then sobered — their view of how climate could change had shifted irrevocably. The European team reported seeing a similar step within at most five years (later studies found a big temperature jump within a single year). ‘The general circulation [of the atmosphere] in the Northern Hemisphere must have shifted dramatically,’ Dansgaard’s group eventually concluded.” ~ The Discovery of Global Warming by SPENCER R.

Humans Have Destroyed 50% Of Earth’s Wildlife In The Past 40 Years

Humans Have Destroyed 50% Of Earth’s Wildlife In The Past 40 Years

Wild animal populations on land, sea, river and air have been decimated over the past 40 years. According to a new report, 50% of all wildlife on Earth disappeared between 1970 and 2010.

This rapid, catastrophic species loss is due to human overconsumption and the destruction of habitat necessary for species survival.

According to The Guardian, researchers at the WWF and the Zoological Society…

well after reading article after article about how we’re essentially at the mass extinction stage of our geologic epoch and could potentially see the end of human history in the next few generations really doesn’t get me too stoked on my already shaky future in this world 

i mean i’m naive enough to hold out hope that with all of humanity’s advances in technology and science, we’ll have to adapt and figure something out. and i think the only way that will happen is if we’re dealt heavy blows from mother nature. like people in my environmental politics class said, the only way humanity is going to get it, is if shit hits the fan [temporarily] real quick.

New Parasite Threatens to Wipe Out Tadpole Population

The tadpole population worldwide is vulnerable to extinction due to a deadly parasitic infection, lending further credence to the sixth mass extinction event. Frogs from six countries spanning three continents were tested in a study led by the University of Exeter and The National History Museum, UK. Tadpole were from both temperate and tropical regions, including oceanic islands, were found to have this infection. The newly discovered parasite is a type of protist — a mostly unicellular organism with its own nucleus and a distant relative of the Perkinsea. Protists are responsible for mass mortality of shellfish populations. Evidently, protists are largely found in aquatic environments.

THE SCARCITY OF AMPHIBIANS

Amphibians are one of the most threatened animal groups in the world. “In 2008, 32% were listed as threatened or extinct, and 42% were listed as in decline.” Amphibians, and frogs in particular, are known to be extremely sensitive to infectious diseases; these have often been linked to mass decline and extinctions seen in their population.

POLYMERASE CHAIN REACTION

In the study, a total of 182 tadpoles representative of different families of frogs over the geographical area were examined. The infectious parasite detected in this study was found to be present primarily in the livers of tadpoles. The DNA obtained from tadpole livers was amplified and analyzed using a common laboratory technique called the polymerase chain reaction. This molecular method allows sequencing of the parasitic DNA. The sequences obtained from all the samples of tadpoles were aligned to find any repetitive patterns and were then mapped to known DNA databases to trace the ancestral origin of this unknown parasite. This exercise revealed the similarity of the protists infecting the tadpoles to the Perkinsea species. These also had very few differences from another type of protist that was recently linked to mass mortality events in tadpoles in the United States. Another notable fact in that this parasitic infection is rampant in various stages of tadpole development, not just concentrated to a single one.

Do We Want To Live in A World Without Frogs?

It is imperative that future studies address the mechanism of how the new parasite inflicts its damage, which might give a clue to curbing the outbreak. Frogs do seem to have a thumb on what could be tipping the balance of our ecosystem. We should pay more attention to what they’re trying to say.

The Last Lullaby

I am afraid for my children.

They will be born into a world with problems that my generation and the past have cultivated.

We are amid a 6th mass extinction.

America is controlled by money and religion. A cult the praises the end of days.

I look outside and see a beautiful earth that hangs on a thread.

In all of the worlds might, it is but a fragile piece of glass in a cosmic storm.

We have drifted since time began, with human’s existence the sum of time and chance.

But time is ticking and I don’t think our society hears it

Our elders react out of fear and they control far too much.

The youth are swamped by social media and control too little.

We are diluted with ego and attention.

I can feel the air getting thinner.

Science is our only chance, technology will be our greatest savior or our doom.

We must make change and we must rally for it.

Or there will be only be starving children to sing lullaby’s to.

Scientists Warn We Have Entered the 6th Mass Extinction

Scientists Warn We Have Entered the 6th Mass Extinction

A scientific study reveals that a variety of animal species are dying-out 100 times faster than normal. In other words, some species are rapidly becoming extinct within 10 years, instead of a more typical 1000-year time span. There is no longer any doubt: We are entering a mass extinction that threatens humanity’s existence. That is…

On the heels of Laudato Si, this video is a short summary of a new study giving more evidence of the mess we are in.

“There is no longer any doubt: We are entering a mass extinction that threatens humanity’s existence. 

This is the centre of a new study by a group of scientists including Paul Ehrlich, the Bing Professor of Population Studies in biology and a senior fellow at the Stanford Woods Institute for the Environment. 

  • Ehrlich and his co-authors call for fast action to conserve threatened species, populations and habitat, but warn that the window of opportunity is rapidly closing.”

  • We emphasize that our calculations very likely underestimate the severity of the extinction crisis, because our aim was to place a realistic lower bound on humanity’s impact on biodiversity,” the researchers write.
  • Cause and Effect - To history’s steady drumbeat, a human population growing in numbers, per capita consumption and economic inequity has altered or destroyed natural habitats. 
  • The long list of impacts includes:land clearing for farming, logging and settlement introduction of invasive speciescarbon emissions that drive climate change and ocean acidification, toxins that alter and poison ecosystems.
  • Now, the specter of extinction hangs over about 41 percent of all amphibian species and 26 percent of all mammals, according to the International Union for Conservation of Nature, which maintains an authoritative list of threatened and extinct species.


  • “There are examples of species all over the world that are essentially the walking dead,” Ehrlich said.As species disappear, so do crucial ecosystem services such as honeybees’ crop pollination and wetlands’ water purification. At the current rate of species loss, people will lose “many” biodiversity benefits within three generations, the study’s authors write. “We are sawing off the limb that we are sitting on,” Ehrlich said.


  • Hope for the Future. Despite the gloomy outlook, there is a meaningful way forward, according to Ehrlich and his colleagues. “Avoiding a true sixth mass extinction will require rapid, greatly intensified efforts to conserve already threatened species, and to alleviate pressures on their populations—notably habitat loss, over-exploitation for economic gain, and climate change.” the study’s authors write.In the meantime, the researchers hope their work will inform conservation efforts, the maintenance of ecosystem services, and public policy.

Co-authors on the paper include Anthony D. Barnosky of the University of California at Berkeley, Andrés García ofUniversidad Autónoma de México, Robert M. Pringle of Princeton University, and Todd M. Palmer of the University of Florida.By Rob Jordan, Stanford Woods Institute for the Environment.

Earth faces sixth ‘great extinction’ with 41% of amphibians set to go the way of the dodo

A stark depiction of the threat hanging over the world’s mammals, reptiles, amphibians and other life forms has been published by the prestigious scientific journal, Nature. A special analysis carried out by the journal indicates that a staggering 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened.

Many species are already critically endangered and close to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing from the wild, it now appears, are animals that are currently rated as merely being endangered: bonobos, bluefin tuna and loggerhead turtles, for example.

Screw the animations! (No youtube! No. For now no uploading i takes so long! At least for now in my case) Oh yeah, the thing I wanted to say. How about Quarternary Or Holocene Park? Maybe to the future it's going to be like a Cretaceous Period. (If humanity, including you and I are not careful this 6th mass extinction could be a success. (NOT GOOD AT ALL) Maybe not a success. (YES NO EXTINCTION) Maybe in between? (STILL NO) You may not be a fan of video games, but there a couple of cool games...

Reverse Jurassic Park has done the Quaternary Park concept quite well, but a Quaternary Park in our own time period would be what we call a typical zoo (unless they resurrected some recently extinct species).

While I don’t play games frequently, I appreciate the work that goes into them. Saurian, for instance, is doing a wonderful job.
