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.

The 6th Mass Extinction on Earth has Begun

Troubling evidence recently released by a group of scientists including Paul Ehrlich, the Bing Professor of Population Studies in biology, has  show a large increase in the number of species lost over the last century. The numbers above each bar represent the estimated values for extinct vertebrates. The image above shows that since the industrial revolution, species diversity has been rapidly declining in response to human activity including:

  • Destruction of habitats
  • Introduction of invasive species
  • Climate change
  • Destruction of ecosystems because of pollutants

Erlich and his colleagues do offer hope for the future. If rapid conservation efforts are undertaken now, then  such a dramatic ecological event can be avoided. It is more than likely that if such an even were to occur, the human race would suffer itself.

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…

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.

We race towards extinction in our mad stampede to nowhere.
The 6th mass extinction: do we really know what that means?


We are walking towards the sixth great mass extinction event on earth and the majority of people are still not aware of the magnitude and dangerousness of this event. Earth’s most precious treasures are being destroyed due to the massive and abusive exploitation of natural resources. Species are disappearing because we are destroying their natural habitat. Soon, we will be the ones begging for our lives.
Please take some time to read this article and go through the shocking figures.

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.

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…

The Holocene Extinction and a brief history of the five mass extinctions

As that as I write this, we’re currently going through or entering what is called the 6th mass extinction, or the ‘Holocene’ which has something to do with a large diversity of animals on this planet rapidly dying off. ( This has been apparently occuring since 12,000 years ago to now ) These species that have died off in the last 100 years would have taken almost 11,400 years to go extinct. These extinctions are having to do with are impact upon the world we live in and its environment like pollution, habitat lose; us destroying land masses that animals have taken resident in and building over them, this drives the animals to have to flee, and become completely homeless, and something to do with an introduction of invasive species and increase in carbon emissions that cause climate change and ocean acidification (if you don’t know what this is this the ocean pretty much losing its pH levels do to uptake in carbon dioxide, which is produced by us into the atmosphere and dissolves into oceans, lakes, and rivers, pretty much large masses of water.)–
also a little brief run over of the five mass extinctions
-

Ordovician-Silurian Extinction:

- Happened between 447 million and 443 million years ago. Two pulses of extinction occurred, 4 million years apart, wiping out 60 to 70 percent of all species.

  - Late Devonian Extinction:
- Happened 375 million to 360 million years ago. Extinction event lasted up to 20 million years, wiping out 70 percent of all species.

- Permian-Triassic Extinction

- Happened 252 million years ago. Called ‘’The Great Dying’’, Earth’s largest extinction event wiped out  out up to 96 percent of marine species and 70 percent of terrestrial species. Trilobites were completely wiped out during this extinction.

- Triassic-Jurassic Extinction:

- Happened 201.3 million years ago. Up to 75 percent of all species wiped out.

- Cretaceous-Paleogene Extinction:

- Happened 66 million years ago. 75 percent of all species out. All nonavian dinosaurs were wiped out.

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.”

Extract  below ….

  • 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.
