- čas přidán 21. 05. 2024
- Earth’s history has been marked by five great extinction events. With the current background extinction rate 1000 times the normal, have humans brought about the 6th mass extinction? The changes our species has wrought upon Earth, its ecology & climate, has led geologists to compare us to a geological force akin to volcanoes, and terming this era the Anthropocene period (“Anthropo” meaning ‘human’). Will it witness the greatest loss of biodiversity ever? What does the fast-changing climate mean for the future of humans? Experts weigh in on these questions in this documentary.

I have CZcams Premium, but thanks to Spark I still get to watch ads.
🤣🤣😂
At least i can skip these ones 😂
Indeed, I am paying for premium as well. So why are we seeing these damn ads on this channel?!
I think spark feel their viewers actually enjoy adds 😂😂
Ooh you lucky!
More ads, you're clearly blessed
There's just something so bone chilling about The Great Dying. It's like the planet dodged a bullet by a hair's breadth, from becoming a dead rock like Mars.
As Jeff once said life finds a way
Mars scares me. Mars is like full blown colon cancer.
I’m a delivery driver in metro Detroit and our sprawl is getting ridiculous. We are putting Walmart’s and strip malls in every field and forest within 75 miles of Detroit. In the past fifteen years since I started it has been dramatic. I drive past Canadian geese families all day long living around the fake run off evaporation ponds we build around these concrete slabs. These geese have been coming to these specific spots for thousands of years and we paved them over and they eat on the little patches of grass on the side of the road. They look homeless to me I feel so bad for them.
Humans are disgusting. Those poor geese (and all the Canadian geese slaughtered after they dared fly near an airport).
That's because no one wants to live in Detroit... so Detroit is trying to run away from itself
Yes. Same over here in Santa Cruz California
Same here in San Antonio TX mainly apartments complexes and maybe businesses here and there but mostly apartments complexes big area's that was open land actually looked better back then now. Then in some places they wonder why wild animals are getting closer to homes when it's us pushing out these animals we make a big thing about wildlife and yet yr by yr they're land gets smaller
Habitat loss is the most dire threat by far for all creatures great and small, on land and sea. It's very hard to watch this happening.
Imagine all the different species that have ever existed.. Boy would I like to see each one in person.. May life live forever!!
Humans are next based off logic it's inevitable!
Then you better see those alive today,as you probably won’t tomorrow.
You don't have to imagine -- just visit the Creation Museum in Kentucky and you can see not only dinosaurs, but also dragons co-existing with humans!!!
Out of all the creatures that have existed I don't think you'd have time to see them all. %99 of all species that has ever existed is extinct.
Would be super cool though! Funny how alot if humans forget we SHARE this planet.. We don't own it.
I think the Green lady has got her P's & Q's mixed up there, 4:00
Tree roots dont cause erosion to my knowledge, they prevent erosion by keeping the soil there !
I swear I thought the same thing I couldn't really get into it. She looked like she didn't even know what was going on... lol they could have interviewed me instead.
She meant weathering
@@user-oy7od3od3qthe weathering of the roots? 🤔😁
It's incredible to think that this happened on the same planet we're on right now!
Not really but sort of
@@Prometheus7272yes but no 🤷♂️
Excellent explanations. I like the explanations
Special thanks to the camera man who traveled in time to film everything.
You're welcome.
It was fun.
rofls!
Jesus. Haven’t heard this one before
@Gizmo - and maybe he was the one of the old mysterious "Sages" who lived for a long time.
Maybe even the old Babylonian antediluvian Alulim or Alalngar. You know - from the time before the Flood, a Golden Age of Gods.
Yeah, the man was quite good with a camera and commited too. Respect. Quite a balls on that guy to do it.
Somebody like Plato, his pupil Aristotle who of course was taught Alexander the Great/Macedon everything he knew, hell even Solon - nobody could hold the camera like that.
They all tried and they have failed :)
Gizmo, we're not doing this joke anymore
I am surprised by the low quality of information about the extinction events in this video.
PBS Eons and many other CZcams science channels cover this topic much more accurate and concise.
Please consisider Qarl that this documentary is packing 5 extinction events over millions of years into 48 minutes when it could last 48 days.
I agree. In fact, that's what caught my attention. Little explanation of events and a lot of rambling about cause and effect relationships.
Still, this is all theoretical... At best it's educated speculation. I'd say it's highly debatable as to the degree of accuracy of ANY documentaries dealing with this topic.
I also find it suspect that this particular documentary is pushing the carbon-caused global warming angle, as well as pushing for the genetically modified food in order to weather the next extinction event. They are always using fear to try to push their agendas onto us. "We need to tamper with our food or we'll die from the next extinction event!"
Also, trying to compare humanity to the Dodo Bird as far as becoming extinct in a short time, is a really weak argument. Unless we're expecting something to come and hunt us into extinction, I don't see why anyone would seriously bring up the Dodo, lol.
Fair enough, and I assume they know the difference between adjectives and adverbs
We know very little of the particulars of these events. There are some correlations and statements that can be made from the available sources of information towards this. Our brightest minds are trying their best to understand it. If you have any meaningful input, I am yet to see it.
….why wasn’t the great oxidation event included on this list? The worst extinction event that killed off close to all prior anaerobic microscopic forms of life.
@@praisejesusrepentorlikewis6218 Just stop bothering people.
Maybe because the great oxidation event doesn't have fossil evidence
Vol 66 (2016) of Bioscience has the geologic explanation you seek. NASA has a great write up from 2019 on the geo evidence discovered to better prove the oxi event.
The colloquially known "big five" extinction events don't include the GOE. All of the big five occurred AFTER complex life emerged. During GOE life was still unicellular.
@@susmitislam1910 makes completely sense to me
What a wonderful documentary
Not really...
Each geologic period ended with an extinction event. The others were not as severe as the Big Five.
Even small power outages can freak out small communities because people can’t get things from stores because the stores close down because you can’t pay with card or cash through their systems. People will freak out and lose their minds over the smallest things.
I am looking forward to this one
What
Me too, Probably the only way These power hungry psychopaths will get dealt with.
@@opethfantoo3140 ill jump on that bus too! Doc told me i have x amount of time. I went home and packed a bag.!. LOL
we ARE "this one"
The video or the next extinction event?
definitely right there sir...
I love this video
Aren't the "trees" mentioned at the beginning of the film the fruiting bodies of Prototaxites , one of the earliest terrestrial fungi? Don't miceilia (sp) hold soil thus help prevent erosion?
The 252 million year old extinction event was associated with the Basalt from the Siberian Traps. Enough Lava came out to cover all the Earth 10 feet deep in basalt. The Antipode was in Antarctica where a very large impact event occurred. The one at 66 million years ago only has enough lava to cover the Earth a mere 3 feet deep. The antipode is the Chicxulub Impact event. Giant impact events fracture earth on the opposite side of the earth. The energy re-focuses at the antipode using reflection, and refraction of energy waves.
Leeweeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeec😂😂v
I get the chills looking at photos of the Siberian Traps. Read a book a few years ago on that event, it was pretty terrifying.
@@geslinam9703 If you think about it, the space rock that zapped Antarctica around 252 Ma was a lot bigger than the space rock that zapped Chicxulub at 66 Ma. It made a hole the size of the state of Arizona, and fractured the Earth at the antipode in Siberia, and leaked Lava for millions of years. The Lava was up to 4 miles thick in Siberia. Now that is what I call a Lava flow. But it released so much acidic gasses that the Earths Oceans and land had a 90 Plus percent die off. Acidic Oceans. Fortunately this is a very rare event.
Mega Zaps are around 186.6 million years apart. I have often wondered as to why some species survived, when most went extinct. I suspect the ones that were underground, or underwater, or in caves had a chance to survive, but if you were big, and out in the open on ZAP DAY, you got blasted, or cooked, or blown away, literally.
Far better documentaries on this subject out there.
A constant state of flux always changing is the norm and I find it very interesting that people usually think of geology as the big determining Factor for Global change when there's another one that's at least as effectively as geology is when it comes to making global environmental changes and that is biology which is seldom discussed outside of the scientific community and I think we should maybe do something about changing that and bring biology into the public realm of discussion.
More people need to see this documentary. The most clear and concise recordings of cause and effect. I'm no eco-warrior...but we need to CHANGE. This made me cry and it's humbling. Thank you for being here to educate. Today, I don't want to bring a child into the world, because I'm scared..And people are doing..........not a lot. It's terrifying.
I agree we need to change but the change has to be done logically and not hysterically. There was no mention of using nuclear power generation.
You just want to feel important. There's nothing wrong with the planet and there never is. At one point in our history around 90% of ALL LIFE was completely wiped out. It always comes back. Maybe stop thinking that the earth is yours forever. I mean, nothing exists forever, at least not physically.
Not a pro, but humanity playing God is only going to get us so far. We can't change what natural science dictates, with that I fully agree. The worry that I have personally is the impact were having on the speed of change. That is the part that's unprecedented.
@@OnideusMadHatter Raw nerve? It's upsetting when stuff dies. Maybe not the mosquitos that keep biting me coz of THE MASSIVELY OVERCOOKED HEAT AND HUMIDITY. But that's just my opinion. Just saying I'd rather that life stays as comfortable as possible on this planet for as long as possible. In no way does that make me feel special or important. Only another one of the (around about) 7 billion people trying to exist here.
Comments like yours are the very reason hysteria is around Be logical nit looney
I thought root structure help to stop erosion
Find a patch of hard dirt or rock - pour a glass of water over it and see how much sediment you get. Now bust up the dirt with a hammer or shovel and pour some water over it. Root structure helps soil erosion now but when plants first started to colonize the land the starting point or square one is not like we are used to it. These were pioneers if you will - now the land has had plant life for half a billion years and you have a variety of plants with varying root structure and ground cover from decaying material. Many of these are the shorter plants, mosses, algae and/or fungi that grow close to the ground.
And we also stupidly thought if we give our politicians more of our money in taxes they were going to change the climate. LOL Suckers
Well science changes every 5 years lol.
🤷♂️ we still plant trees beside our creek to stop erosion. It works. Trust but verify everything you see. Besides Algae type of plants have minimal root systems.
I agree. False statment
It does!
@@aarongoodwin4845 Yeah sure. Like giving them money ever did much good. They get rich and most of us get poorer. But people will certainly vote to raise our taxes for such a idea. Sorry but we are all going to become extinct one day if we pay more taxes or not. And the planet will be just fine.
Dang! Glad I'm here.
(That one fellow looked familiar. Is that officer Jim Dangle, Reno 911?)
Very interesting! Well done!
The odd thing about this... is its appeal to how we should perceive change over time - though it's the exact opposite of a rational perception regarding change over time.
13:10. No no no! Lystrosaurus was not the ancestor of dinosaurs and mammals alike. Lystrosaurus was a synapsid, and synapsida is the group that gave rise to mammals. But dinosaurs were sauropsids. The two lineages had already split long before Lystrosaurus evolved.
Correction, Dinosaurs were Diapsids. You are right that the Synapsids gave rise to Mammals and that Synapsids did not give rise to dinosaurs.
Diapsids are named for the 2 Fenestra on the sides of their skulls, where Synapsids have 1.
Glad you caught that too. :)
The "experts" struggle to memorize all those theories ... you have to be really really smart to memorize hundreds of theories.
I'm still waiting to see REAL Dinosaur Bones,
@@milfinu There are plenty. Bible-Belt Sunday School "history" and other mythology is for childhood, grow up, look at the science.

I wonder if the asteroid had an effect on volcano activity? 🤔
It seems to me that the Earth is usually in balance keeping volcanoes in check most of the time. It seems reasonable to expect an increase in volcano activity shortly after the asteroid's impact. Like ringing a giant bell.
There's been 6 mass extinctions in earth's history and one of them they believe could have been caused by volcano's
@@wantsome-zs5sq was that the Permian? I think the evidence of volcanic activity (Siberian Trapps) has been connected to that extinction.
I did read or see in a documentary once that an asteroid could have triggered volcanic activity. Makes sense of if you think about it.
was the black hole influence from center of galaxy,as of now
@@wantsome-zs5sq they legit say that when the asteroid hit, massive green house gasses were admitted into the atmosphere BECAUSE of the volcanic activity after the asteroid struck…

Amazing to think that this happened on the same planet we are on right now! 🌎👀
This is the scariest video I've ever seen. My son came home from school saying he will not have children and I took it ,like most, you will change your mind one day.
As an adult he tells me he would love to have children but won't because the world will change and he couldn't do that to them.
It's heartbreaking truth this video is what he means
Its an interesting generation gap. As a teen, I consider this comforting. Humans will never stop fucking shit up, so after accepting our inevitable demise its nice to know what will happen and that earth goes on existing. I think it goes to show how utterly hopeless my generation is- literally being born into the 6th mass extinction i guess we just don't even know what hope is like. More sad than anything.
@@soupsop It is so sad.
Watch this again with friends and do a shot every time they um uh probably think or maybe. It’ll be a very short night.😂
Thanks! Needed a giggle!
It's only a 47 minute video. If one were to do that, after 47 minutes you're BAC level would be well over 1.2!
Excellent explanations of earth’s past & where we are now. New rock type made of plastic says it all for modern human life.

Dust to dust.

This is one of the most interesting documentaries I have ever viewed; also one the most frightening. I like the explanations of the past extinctions & when, not all the facts are not in, it is really made clear with some educated guesses.
"not all the facts are not in, it is really made clear with some educated guesses."

Denial, anger, bargaining, depression, extinction. We are still firmly rooted in denial.
4:19 large trees dug roots causing erotion... roots dont cause this, wind and water do, roots help hold ground not release it
When roots move into the soils around the plants and trees, it loosens up the soils and then the soil is easily moved.
@@chuckking4188 it may move but then is replenished with rotting foliage, and increasing the soil around the forests floor, making more area for new plants, , simple science

Are you serious?
Totally agree. Scary to see the other replies. Glad to see I'm not alone though.
The Permian Extinction part forgot to mention the Siberian Traps. Hmmmmm.....
Yeah, it was kind of weird wasn't it?
How would trees cause extreme erosion and the loss of soil into the oceans? Looking for an explanation.
If you're looking for an explanation then don't ask CZcams. Ask the internet.
the erosion could be because land was rockier than it is today, the carbon hadn't been pulled out of the atmosphere and into the earth's landmass to the extent it is now . Leaf litter getting washed into the ocean causing algae blooms causing dead zones is a real thing that is dealt with even today. basically the ocean gets double fertilized
Yes, I was concerned about that too. The explanation that the large trees had large roots that broke up the ground which then washed into the sea made zero sense to me.
@@dogphlap6749 yeah trees are really good at holding dirt together, but get a seed in a crack on the side of a mountain, and, well...

Obviously, the Earth has always been on a knife edge. Plus, it is amazing how many changes have occurred. Also, the severity of some of the changes in very short time periods. Tragically, human self-interest will be paid for many times over.

@@steadychasingmoneybands6213 I agree. However, there is no reason to preclude human self-interest as contributing to change as well.

Almost random sound bite inserted "Lystrosaurus was the ancestor of both dinosaurs and mammals alike." Sorry but Lystrosaurus was a synapsid and could not have been the ancestor of dinosaurs.
And your credentials to rebut this statement are...... ?
@@christopherlane5238 You don't need credentials to understand basic anatomy, you NPC weirdo. It's been rebutted by any legitimate scientific article/documentary/talk that mentions the origins of Dinosaurs. You can likely find something about it if you check out the Royal Tyrrell Museum videos.
Let alone be the ancestor of BOTH dinosaurs and mammals. (Not even related to current mammals, btw!)
I’m impressed that the nature of plant roots changed so much! Today plant roots are considered to stabilize soil and reduce erosion. I have NEVER before heard of plants increasing erosion. Seems an unsound hypothesis.
Relative and contextual in understanding. Before there was no plant root system as it grows, develops and evolves it is displacing soil, nutrients and by products. The much better comparison would be what phosphates, nitrates, acid rain and other newly developed erosion conditions are doing to the current long standing normal soil conditions before them. I think at least this is what my layman brain took away from this as I was watching it.
Today we have lots of unstable loose surface made up of very small particles called soil. Soil will always be subject to erosion and is easily washed away. However, plants limit this by binding the small particles together with their roots so that it is not so easily washed away.
Back at the start there was no soil, just very stable rock that did erode but at a very slow rate but it could not be just washed away. The roots broke up into the much smaller pieces that we call soil. So, then the rock could be, and was, washed away.
Lol I'm sure you know so much better than the thousands of scientists across the globe who have been working on this information for decades. 🤣
@@chloerene7858 Every report I’ve read, or non-sensationalized video I’ve watched that addresses the subject of paleo erosion states that the rate of erosion was much higher before plant life because the rock was more directly impacted. This is the ONLY video I’ve seen where the converse is proposed. So… I don’t see the “thousands” of scientists you reference.
As a kid we learned that the plants helped break up the rocks which enabled minerals to be leeched out by subsequent generations of plants.
At 22:24 he starts to talk about the current "perfect storm" of conditions and then adds "not just climate change induced by humans" and then starts to enumerate them, 'deforestation', 'urban sprawl', 'habitat fragmentation'... All, notoriously, 'induced by humans'
One of those videos that one should watch... and then watch again immediately.
4:00 since when do trees roots digging into the soil cause erosion? Doesnt it hold the ground?
I had the very same thought. Lack of vegatation creates runoff. Trees stabilize the surrounding soils. That's what I've always understood.
@@virginiaotter6981 I think that they are talking about trees breaking up volcanic rock with their roots. Earth's crust was mostly rock initially and the first trees would have caused fracturing allowing the first runoff I suppose. A better explanation of something as counterintuitive would have been nice.
@@booklover6753 I'm inclined to agree. Trees will split granite, and pretty much any other rock. Also, lichens break down rock.
@@grunthos1 Have you ever noticed how friable the soil is in a burnt out stump hole?
the basic presumption at the video beginning is that man can actually do something about a polar shift, inbound asteroid, etc. Do I need say more?
Sure he can. Didn't you watch the movie Armageddon, mate? (Just kidding.)
But Mr & Mrs Globalist want us to believe the negative effects of their phony "Climate Change" is caused by human activity, so they can suck carbon taxes out of us & limit our lifestyles (housing, transportation, energy usage, etc.). In reality, only a small fraction of it is caused by man. Most is driven by solar activity/cycles & other stellar influences.
The incoming Planet X (aka Nibiru) of the small Nemesis star system, which passes ours each 3,600 years, is causing much of the big increase in Sun/solar system/Earth changes we've seen in the past few years (volcanic eruptions, quakes, sinkholes, meteors, wild weather/storms). These will become more frequent & intense until the planet's flyby of ours in the next few years, which will be a HUGE disaster-fest! NASA discovered & publicly announced PX in 1983 then went dark about it. Elite/govts/military have been prepping but keep the Little People in the dark to prevent panic. Stay safe. - PX researcher 6 yrs
We're better off doing what Bill Hicks said and not Bill Gates.... and hoping for the best.
Except that if you actually watch the rest of the documentary they're talking about the actual issue.
WE are the factor driving the next extinction. It's unlike any mass extinction before, in that for once there *is* something we can do about it.
@@johnathan6642 Thats a load of shet
@@NoName-qs6ei i mean you can believe that if you want but if you look at the rate species are dying if we don't stop then we are literally going to cause the definition of a mass extinction. 96 percent of recent extinctions are attributable to humans. We spell death for any megafauna that exist in the area. The vast majority of biomass on earth is humans or livestock. I'm not even talking about global warming because I know that some people don't believe in it. I'm talking habitat loss, pollution, and hunting. Things that all solid evidence can agree with.
Thank you so much for this. I so admire these scientists. Men and women at their most noblest. ❤
"IGNORANCE IS BLISS" scary visions..
Hi. Great work, especially the very long-term correlations between CO2 levels, temperature, and ice-melting. However there's one aspect of temperature rise I've never seen covered on a climate video, and that is "how much extra water evaporates in the tropics for each degree of temperature rise?" Obviously this is important, because if more water evaporates in the tropics than melts at the poles, the sea levels will go down, not up. Humidity, rain, and cloud cover will also increase, the latter reflecting away sunlight which will lessen global warming, but the humidity will increase it, like a heat trapping blanket.
A major factor can be seen with a glance at any globe of the Earth: There is ten times as much area for evaporation in the tropics as there is area for melting at the poles. So which has the most powerful effect on sea levels, or have we reached a natural balance? I'd suggest that until we have some hard our computer models are no better than educated guesses.
Confounding things further is that we use Mercator's two-dimensional projection of our three-dimensional globe, and this grossly distorts the relative sizes of polar areas and tropic areas, making the former look far larger than they are, and the latter smaller. We see a full width band of white at the top and bottom of the map and tend to panic when considering it all melting. It's more illusion than substance, but it still conditions our thinking with an unhelpful distorted perspective.
A simple experiment could help sort this "melting versus evaporation" equation out. Make low flat-topped forty-foot triangular glass-houses, modelling the correct size dimensions of segments of the earth between the pole and tropics, and partially fill each with salt water. The bottom of each segment will vary according to the known contours of the sea floor, so the total quantity of water in the segments will be proportional to the oceans as well. Each triangle's apex, representing the polar area, would be chilled to the average Arctic or Antarctic temperature. These apexes will become mini- icecaps. The much wider bases of the triangles, representing the tropics, are heated to sea temperatures at the equator. Evaporating water at the base would migrate to the cold apex, and condense, as happens on earth now. This experiment could accommodate ocean currents, but it could not model weather air movements very well. It could at least give us a crude base of real-world knowledge. Computer models alone are not good enough, especially when they don't include measurements of evaporation. (Garbage in, garbage out.)
Next, raise the temperature one degree C both at the poles and equators, then observe and measure. And so on. An experiment like this (but hopefully more sophisticated), could determine whether the hypothetical "tipping point" actually exists, and at what temperature it kicks in if does. Thanks for a very thought-provoking video, keep up the good work. Cheers, P.R.
Some Great points put across here, and very well delivered.👏🏼
Also the eastern Antarctic Peninsula Ice Sheet has expanded since the start of the 21st century, also there's been an increase in Sea ice.
@@stevewildeagle965 Thanks Steve. The ice-sheets expand and contract with the seasons, but the thickness of ice is the main concern. The climate change videos always focus on a dramatic spring collapse of ice into the sea, and most people are unaware this is a visual form of "cherry picking the data". That's not to say there's nothing to worry about.
I'm more concerned about my poor grammar. In the second paragraph I said, "until we have some hard our computer models---". I meant to say "--have some hard DATA our---". Also, there was a missing "IT" in my last paragraph. If I cannot communicate my thoughts accurately I'm doomed to drown alone in the rising tides of ignorance. Toss me a life-raft if you get time. Cheers, P.R.
@@philliprobinson7724 Your information was so well delivered, and informative I became way to involved with taking in all that data.
You'll never be doomed unless you accept defeat, and you sound like someone that'll just Ascend to new heights, rather than sink to lower vibration.
Love and Light Steve Wild Eagle ♥️🌅🦅
@@stevewildeagle965 Thank you for your kind words Steve. My posting was way too long and many people wouldn't bother reading it all, but the truth is, real science needs more context than short simple "sound-bites". Please note, I'm not a climate change denier, but rather that we need to honestly look at all possible angles to get the best grasp on the issue. Cheers mate, P.R.

The current ice age we live in has flip flopped between interglacial and glacial periods at least 17 times!
Great

interesting, frightening, informative, engaging
Also, when plant life is overabundant, the atmosphere also gets to high a concentration of oxygen.
But with that comes low CO2, which is a requirement for most all plants, which then die off since
there's no food for them to continue growth. As they die off, the bacteria consume those and you'd get lts
of CO2 again, and this can happen rapidly from a geological point of view, like every
million years or so.
We don't any of this to be fact. This whole video is theory.
Aren't the Ordivician-Devonian "trees" mentioned around three minutes in actually
This is a new one for me. Thank you very much! If you can’t tell,s**t’s about to get real.
Shit's already real. Pay attention.
@@prometheusunbound7628 Not even close to what is next. I’m paying attention.
The Vredefort Crater in South Africa is 190 miles wide as opposed to the 110 miles of the Chicxulub Crater. The latter impact ended the dinosaurs 66 million years ago. Vredefort was 2000 million (2 billion) years ago. One can scarcely imagine what happened.
back then only bacteria existed and bacteria doesn't fossilize so we don't know how much of an affect it had.
May want to fix "two thousand million years ago"
@@trashyhobo4957 it just means 2 billion, jack is correct. No fix needed
haha asteroid go brrrr
Fuck that. I just need to survive right now and I could eat whatever the hell I want and I just need to throw my thrash anywhere but not in my home. I could even throw it just in my neighbours door
I never thought I would watch Al Bundy in a documentary about climate change.
amazingly,, we human beings have only been here a short time since the disappearance of the monumental extinctions in the past. Perhaps we're one of them eons ago? I (for one) wasn't here to OBSERVE the PAST extinctions, but maybe I'll be here to see the next one.
“Unless conserved…” humans can be mindful but to think we can stop a mass extinction event is the pinnacle of arrogance
We certainly make little headway regarding global warming. Maybe it's arrogance to suppose that we might. As a species, we're too short-sighted to be regarded as intelligent. Buoyed up on a life-raft of faith, but not bothering to paddle.
Its stupid to think we can't stop a mass extinction that we are causing. Does that mean I believe that humans will mend their ways? Absolutely not. Humans are too stupid, selfish and greedy.
@@fred_2021 You make a good point, to me it seems that humans develop enough intelligence to destroy themselves before they develop sufficient intelligence not to. I think it has happened many times before.
Maybe next time ?
I think the pinnacle of arrogance is causing a mass extinction event. Not sure how you can top that.
We can stop a mass extinction being caused by our own carelessness.
Life will undoubtedly go on , unfortunately the human race may not , and it’s no more than we deserve 🤷♀️
Undoubtedly ? What if nothing survives
Have said this for many years extinction six we are into it and we wont stop it
Whenever the next extinction comes along is completely out of our control. We're just along for the ride.
Yea been trying to get my son to understand he's 29 💀😬 he's in denial about global warming, among other things 😞
I live in NY and democrat politician's are selling building permits like candy. They just stripped 100 acres of trees on long Island for Amazon warehouses. Aren't these the same politician's crying about climate change? 😂
don't understand. they're saying the tree roots caused erosion?
don't roots hold the soil in place, if not than what was the dust bowl all about than?
Over the longer term, the roots dig into the ground and break rocks apart in a way that hadn't been happening before plants lived on land.
@@wwoods66
Highly unlikely. Just fear-mongering pseudo-science.
Any mention of milankovitch cycles?
Whatever gave us consciousness? Gave us our nature too.
No prizes for guessing whats going to cause the next extinction event.
*Recurring Micro-Nova on the Sun !*
(Every 12,000 years...our 12,000 years is up any day now !)
@@Snailmailtrucker lol...only a few know about the cycle. Not sure if micro nova has enough support yet. It's too frightening for the masses anyway. Keep it a secret and we can at least die in peace. S.O? :)
@@Snailmailtrucker Now that sounds good.
@@Snailmailtrucker I haven't heard of this. Now I have a new rabbit hole to search for. 🐇
Plot twist: Aliens from Omecron Persei 8, because we canceled their favorite show thirty years ago and just now found out.
Imagine that, earth has cycles of warming and cooling...........
19:50 Just happens to casually throw out there... oh and by the way, we are currently armpit deep in a 6th mass extinction.
A script editor would have been great. Maybe directing some of what they were talking about to make it more cohesive. It feels like discussions were bouncing all over the place.
Really fantastic video I love things on this topic
Until it got to climate change. Lots of bunk. Mankind will become extinct like the dinosaurs. We can not change it. One way or another we all will be gone.
Tina? I knew some nice lady in old "alphabet city" in Manhattan, New York, with that same name. Very fine and funny grandmother we called : Tina Colada, ...among friends and family.
A very old Jewish grandmother from the 1970's old New York... Tina Colada sounds like an awesome handle name for you... in social media circles..
just my silly brain droppings...
Kindest Regards!
even if its a propaganda video like this one?
The UN need scientists to deep dive around the Indian ocean and find how much the huge Chinese fishing fleets have stripped the oceans of all marine life that is eatable
So what would the UN do if they find huge damage caused by the Chinese? Nothing....UN has no power to change anything China does
One word will factually define the earth’s problems ‘overpopulation’ .
0:37 scp 001 when day breaks.
Never considered that 'extinct' might be chilling. After all, we wouldn't be here without it. Oh, well maybe that's the point.
..and we won't be here with it
Someone here asked if the asteroid that caused the dinosaurs extinction may have had an effect on the volcanic activities we experience in our time today.
I think that's a very reasonable question! It's certainly not beyond the realm of possibility 🤔🤔
No
@@breynolds4608 Yes
what? no. entirely unrelated
@@jays2551 I said it was a reasonable question and not impossible. I never said I was certain 🤦🏽♂️ of it.
@@Skillfuljoe23 And I said yes.
