The Sixth Great Extinction: Massive wiping out of species?

Note: Re-edit of “Sixth Great Extinction? And the human? Could he survive?”

Species are disappearing at an alarming rate, a new study finds. Author Elizabeth Kolbert says that raises questions about our survival.

Apparently, in the last half a billion years, earth witnessed 5 extinctions of its species due to natural calamities.

This current extinction process is mainly due to the human species.

There are very few extinctions that we know about in the last 100 years that would have taken place without human activity.

I have never heard anyone argue, “oh extinction rates, that’s just a natural thing that would have happened with or without humans.” It’s just pretty much impossible to argue that.

The current extinction rate could be more than 100 times higher than normal—and that’s only taking into account the kinds of animals we know the most about.

Earth’s oceans and forests host an untold number of species, many of which will probably disappear before we even get to know them

The new study that’s generated so much conversation estimates that as many as three-quarters of animal species could be extinct within several human lifetimes, which sounds incredibly alarming

What is clear, and what is beyond dispute, is that we are living in a time of  very elevated extinction rates, on the order that you would see in a mass extinction, though a mass extinction might take many thousands of years to play out.

Island species are very vulnerable to extinctions for a couple of reasons.

1. They tend to have been isolated.Humans have been removing the barriers that used to keep island species isolated. New Zealand had no terrestrial mammals. Species that had evolved in the absence of such predators were incredibly vulnerable. A staggering number of bird species have already been lost on New Zealand, and a lot of those that remain are in deep trouble.

2. We brought in invasive species. So, places that have been isolated for a long time are very vulnerable. Species that have a very restricted range, that exist only in one spot in the world, those tend to be extremely vulnerable. They have nowhere to go and if their habitat is destroyed, say, then they’re gone.

We are now changing the climate, very rapidly, by geological standards.

We are changing the chemistry of all the oceans.

We are changing the surface of the planet.

We cut down forests and burn entire forests

we plant monoculture agriculture, which is not good for a lot of species.

We’re overfishing. The list goes on and on.

We dump nitrogen on fields in the Midwest and the fertilizer runs down the Mississippi and into the Gulf of Mexico, and that causes these dead zones.

The sort of fundamental question is: Can 9 billion people be able to live on this polluted planet with all of the species that are now still around?

Or are we on a collision course, in part because we consume a lot of resources that other creatures also would like to consume? That’s a question I can’t answer.

If you give vertebrate species (and we are another vertebrate species) an average lifetime of a million years, and you say humans are 200,000 years into their million years, and you precipitate a mass extinction—even laying aside the question of whether humans will be the victim of their own mass extinction—you can’t expect that same species to be around by the time the planet has recovered.

There are two questions that arise:

One, just because we’ve survived the loss of X number of species, can we keep going down the same trajectory, or do we eventually imperil the systems that keep people alive?

That’s a very big and incredibly serious question.

Second, even if we can survive, is that the world you want to live in? Is that the world you want all future generations of humans to live in?

That’s a different question. But they’re both extremely serious. I would say they really couldn’t be more serious.

Not only the quality of potable water is highly polluted, but even water used for agriculture is generating degraded food. Heck, water is being appropriated by multinational companies from States and costing all citizens the price of drinking.

The quality of air is deteriorating quickly due to traffic transportation and oil burning to generate energy.

It is striking that the advent of this Covid-19 pandemics that spread lockdown of major traffic and industries has cleaned the skies and improved water quality.

The more humans desist from meddling with nature, the better our quality of life will improve.

The main difficulty is how to change this mentality of constant “economic growth” that forces the depletion of earth resources at a gigantic rate?

Nadia Drake, published a conversation with Elizabeth Kolbert in National Geographic , June 23, 2015. news.nationalgeographic.com

Note: I believe that, unless the atmosphere is Not highly toxic, beside the insects and rodents, two species could survive:

1. The owl who can hear a pregnant mice one meter under the snow and 300 meters away and has incredible eyesight at night (100 times that of human) and can sneak on victims listlessly .

2. The hyena who can crush and eat bones and is an excellent hunter individually and as a team.

This precarious existence of human species

A few conditions for the emergence of our species.

Observers have identified two dozen fortunate breaks we have had on Earth to create just the living organism.

Not to mention the hundreds of conditions for the formation of human species that is Not within this scope.

If the Sun was larger, it would have exhausted its fuel before Earth could be formed because the larger the star the more rapidly it burns.

If we were two light minutes closer to the Sun we would be like planet Venus that cannot sustain life; Venus surface temperature is 470 degrees Celsius and all its water has evaporated driving hydrogen away into space.

If we were 1% further from the Sun we would be like frozen Mars.

If our core didn’t contain molten liquid we would Not have magnetism to protect us from cosmic rays.

If our tectonic plates didn’t collide to produce more gases and continually renew and rumple the surface with mountains then we would be under 4,000 meters of water.

If our moon was not large enough, one fourth the size of Earth, then Earth would be wobbling like a dying top with unstable climate and weather.

It is to be noted that the Moon is slipping away at a rate of 4 centimeters a year, relinquishing its gravitational hold.

If comets didn’t strike Earth to produce the Moon or asteroid to wipe out the Dinosaurs, or

If we didn’t enjoy enough stability for a long time, human would not be what they are.

ringtonesdump.com commented:

Wilson’s remarkable book reminds us that every living thing is the result of millions of years of evolution. We have all arrived here together: the perfect possum, the perfect bear, the perfect fox, the ‘almost’ perfect human.

Now however, we are living in a precarious moment wherein our species, Homo Sapiens, supposedly the ‘smart’ species, is recklessly and mindlessly on course to destroy the rest of life on earth, not by means of a nuclear war but by eating, killing, poisoning, and crowding out all wildlife everywhere, including in the oceans.

Why human species exhibit this consistent strain (and stain) of morbidity?

As usual, I cut through the chase before attempting any explanation or developing on a theme.

I conjecture that the final development of our species, after hundreds of extinctions and near extinction periods, was left with a set of parasites that prefer the human body for their incubation periods.

These parasites disturb the communication links between the over developed Cortex and the two other primitive brains (reptilian and lower mammalian).

The parasites attack the nervous system and stop the growth of the emotional intelligence and save the rational brain.

The end result of these affectation render the human species more prone to kill, maim, physically harm his own species.

Endangered Human species by strained Fact-Resistant behaviors

It’s possible that Human species will become more receptive to facts once they are in an environment without food, water, or oxygen,

More worryingly, Logsdon said, “As facts have multiplied, their defenses against those facts have only grown more powerful.”

While scientists have no clear understanding of the mechanisms that prevent the fact-resistant humans from absorbing data, they theorize that the strain may have developed the ability to intercept and discard information en route from the auditory nerve to the brain. “The normal functions of human consciousness have been completely nullified,” Logsdon said. (Though human species is far more reliant on vision, 80% of information)

While reaffirming the gloomy assessments of the study, Logsdon held out hope that the threat of fact-resistant humans could be mitigated in the future. “Our research is very preliminary, but it’s possible that they will become more receptive to facts once they are in an environment without food, water, or oxygen,” he said.

MINNEAPOLIS (The Borowitz Report)—Scientists have discovered a powerful new strain of fact-resistant humans who are threatening the ability of Earth to sustain life, a sobering new study reports.

The research, conducted by the University of Minnesota, identifies a virulent strain of humans who are virtually immune to any form of verifiable knowledge, leaving scientists at a loss as to how to combat them.

“These humans appear to have all the faculties necessary to receive and process information,” Davis Logsdon, one of the scientists who contributed to the study, said. “And yet, somehow, they have developed defenses that, for all intents and purposes, have rendered those faculties totally inactive.”

Re-Creating a “cohort” of Neanderthal species: It is feasible, but Why?

Our current human species is uniform. The monoculture is source of extinction when facing worldwide epidemics and a serious degradation in climatic changes.

Consequently, re-introducing a former species that was wiped out 30,000 years ago might regulate the survival of mankind.

It appears that the  Neanderthal species had a larger brain (but we are not sure if the network of his synapsis was complex enough to match this current species), and he was of the bigger kind who needed to consume 5,000 calories per day.

A skeletal, up to one million years old, can be useful for the re-introduction of a lost species.

Scientist George Church (56 of age)  would recuperate the DNA to submit it to the sequencing of its genome.

The genome is later cut into 10,000 fragment to be synthesized.

These synthetic fragments are introduced in a cell stump. By repeating the operation as often as necessary, the descendants are generated from the stump cells.

These cells will be inserted in the uterus to develop.

Et voila! Neanderthal species coming back to live among us and protect mankind from a potential extinction.

Church is a pioneer in synthetic biology, a discipline trying to unite complex systems which function Not necessarily according with existing ones in Nature.

In the 1980’s, this professor in Harvard was at the origin of the Human Genome Project, the decryption of DNA of human body.

Church explains:

“All the information in the world (about 1.8 zettabit) can be stored in 4 grams of DNA. The DNA storage can resist desert climate for 400,000 years.

The scientists of Boston are using an decryption archive system that needs no cells to work, and a coding system that enables the location of the DNA extract in the files.

Thus, strong with the availability of DNA sequencer and a computer, the files could be read.

A mother chimpanzee could be substituted in the cloning process.

A long journey to learn the evolution of the Past.
