- Are we really on the brink of a new mass extinction? Palaeontologist Michael Benton explains how scientists trace the history of life on Earth, examines the data on biodiversity and addresses the question we all dread to ask: Will the Anthropocene mark the end of the world as we know it?
Michael Benton is the Head of the School of Biological Sciences at the University of Bristol and a Fellow of the Royal Society. A key theme in his work is the Permo-Triassic mass extinction, the largest mass extinction of all time, which took place over 250 million years ago, where he investigates how life was able to recover from such a devastating event. He has made fundamental contributions to our understanding of the history of life on Earth and he has written more than 50 books, including palaeontology textbooks for students and a children's book on dinosaurs.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
Despite our best efforts, eventually something is going to wipe us out because we can't get our collective asses together right now.
Even if we could it assumes we can somehow prevent it. Most diseases we cant even cure or reduce symptoms and more we cant do . Itll be hard to avoid any kind of extinction no matter what it is. Has nothing to do with the collective. Sounds too fantastical and optimistic and a wrong idea of how extinction happens.
Great work
What an amazing talk.
... as a German Biologist -
Michael Benton is a highly impressive Biologist
and Role Model for the World.
As the World has no respect for Persons like Benton
we self extinct
easy...
I need to listen to more of this guy.
Intellectually sharp...straight-talk!
You did not notice several logical mistakes in the talk, did you?
Can you explain it, please?
@@margaritaorlova6697 Again, please explain!
Reminds me of a temporary duty trip to thessaloniki way back in 1982 :) ...from Athens... and the Mass extinction is well under way... just look out your window at the weather. :)

I am your age and have lived most of my life outside and in the last 30 years so many of insects and birds l have lived with are almost gone. They pollinate our food...so that we have food....and it is too quiet. If we exclude all pesticides, herbicides and fungicides from farming hopefully that will help. With proper care and large organic farms the change in the soils will make a huge contribution in the CO2 arena. Our mono farming practices can be doomesville also. I suggest that every family who have space grow a garden....and teach your kids the same.
Most people just do not understand what you are talking about. They don't notice or appreciate the insects. They don't hear the silence. Too bad, because one day they will -- and then it will be too late...
It's the sun
@@futurebest4952 Motorcycle riders that are old enough to remember know there are not as many bugs in the air today as there were just thirty years ago.. The planet is dying. It is NOT the sun.
Yes it is were I live there are stop signs with no color due to sun uv Ray's it is probably the sun because the uv rays are disrupting the larva for the insects and that explains why there are more in other places.
@@futurebest4952 Interesting theory. I tend to think that the pesticide and poisons that humanity spreads on the Earth have more to do with mutant insect larva that UV rays ever will...
Good
Can we just take a moment to apprrreciate how delightfully the R rrrolls of his tongue?
😂😂😂 he may sound British to us Americans but that gave it away real fast
I don't know what's more frightening. The facts in the video, or this comment section.
Both. Both.
Both. I see the trend to argue the facts and this diverts us from the reality that we could make changes to help ourselves and the other beings on earth get through hard times.
Did not know TED had speakers of this calibre they are normally plastic., sensationalists . Dr Benton is authentic facts, no excitement to blur the accuracy of the subject
Did not you notice several logical mistakes at the end of the talk, did you?
@@margaritaorlova6697 How many times you are going to repeat your insubstantial question?
What can man do against a massive meteorite or if the 'ring of fire' in the Pacific all blows at once? They can panic and kill each other or keep calm and die anyways.
The director of this video should have been fired. The boom camera invading the on-stage presence of the speaker was extremely distracting. The close-up video shots were not static but bounced around, and much of the overall video looked like an amateur production. The boom operator had no business operating the boom like s/he did. At least one of the camera operators needs more practice in a non-recording session. And the director who directed this production produced one of the worst Tedx Talks I have ever seen. The speaker did a great job despite all the things out of his control.
Man, I’ll never watch Jurassic Park the same way ever again. They never woulda made it 😥
Read this guy's book, 'Vertebrate Palaeontology' by Michael Benton

And birds are ALL dinosaurs, still.
Well we See the Future..,?
Yes we know by now and what do we do….what is humanity doing ?
Death stranding sent me here
3:21 Boom in the shot!
At the edge of extinction only Ocean Mechanical Thermal Energy Conversion remains so we can love more often..
Nature bats last
What are Total Species including Oceans from 1500-1600, 1600-1700,1700-1800, 1900-2000? They can't even do data on 2017, how can say there is an extinction of a species? He mentioned 5 animals over 200 years, OH My!!!
Though this bs about this T-Rex is irrelevant in my opinion, he's right. We have been fuelling a heat engine for many many decades (about 20-25 decades), and we felt like a frog in heating water, we could afford that for a long while, I think the sting will be in the tail. It will go haywire in no time at all, 12-20 years, starting within a few years from now. There is not much we can do now, which will have a positive effect, the damage has been done. Within a few hundred million years, there might have been risen a conscious out of some amphibians or insects, and they will find some of the stuff we had been making, and try to guess what killed us off. Who knows.
Irrelevant? Do you know who this is? 😂 He's a well know Paleontologist, specifically the type of Paleontologists who study and write about dinosaurs.
Check out his book 'Vertebrate Palaeontology', it's pretty good
I am a simple man. If I see the names Benton, Ward, Wignall, Hallam, I press like :D
Peter Ward was the one who led me down this rabbit hole about two years ago. I’ll be chasing down the other two names you listed, so thanks!
@@ragereset2795 Glad to hear!

Should be on TeddyX
Aren't you going to be surprised when we pass through the galactic sheet.
When will earth become a burnt out cinder ? We don't know. But it's a Good guess that it will. Good luck folks.
More deck from Ted.
very interesting .... what about Global Climate change ? The Heat Engine...
Good speaker but what was his point?
I've often wondered if some of the previous mass extinctions have also been caused by the rapid spread of a particular species that then goes extinct itself. If this happened over a short period how likely is it that the evidence would exist in the fossil records and would we be smart enough to connect it.
Did not you notice several logical mistakes at the end of the talk, did you?
@@margaritaorlova6697 And once more, please explain!
I have wondered about this as a possible factor as well
Sad
Yeah so what if it happens naturally WTF are going to do??
What we should do is get a puppy.
What ? He was saying ; what ?
TEDx - the place where people come to overthink life.
Well the scientists think the world is ending and the religions of the world predict the world is ending I guess one way or another it’s going to end 😕 bummer
Remind me not to get bitten by a shark....or T-rex!!!
How does 100 per day come to 40,000 per year? That's some fancy rounding.
Robert Bonneau I’d “fell” better if you weren’t off by a whole magnitude. You have even fancier rounding at 365,000. I think you were aiming for 36,500.
@@jt4369 Since you know the answer why did you ask your silly question? Pettifogger
nota bene The point of this whole exercise is to be careful with words and to be even more careful when discussing numbers. I’m sure you’d very annoyed with your creditor if he or she simply “rounded” a 36,500 debt to 40,000.
@@jt4369 You are just a poor, hilarious pedant, unable or unwilling to catch the really important message. And stop wasting my time!
I get the message just fine. And my intention at first was just to make a humorous quip about “fancy rounding,” but it somehow devolved into this. I’m sure your accountant will be as much a pedant as you’re accusing me of being.
As for wasting of time, we’ll put that to the test: if this is truly a waste of your time, you won’t even respond to this.
Good day.
4:00 great white shark does not have the biggest bite force
what does then
It's true a white shark has approximately 4000 psi
While the nile crocodile has up to 5000 psi
nor does a t rex. forget computer projections. seen some of their failures? & what sort of car. a' fact' is when you put them in the ring together & say 'go for it rexy,' i wanna see two 1/2 cars. 'fraid until then it is an opinion. science gives us licence to postulate. not call the unproven a fact
Anyone see Bill Gates say depopulation statement?
Earth is life !!....Species are going extinct, quite a few at that. Are there any new species being discovered ?? On any daydo we get a report of differenciation of a bird or a fish or a human confirmed ?? Every extinction has so far did an'astounding' job of regeneration of life. And supposedly a better evolved human !! Lets do it.
We could start from the flesh eating bacteria. Would have a head start.
I don't think you quite understand evolution. Proliferation take millions of years after an extinction and things don't regenerate. Evolution is genetic modification with shared descent

Don't limit your diet to eating 4 animals. Expand your diet to the millions of species of plants and fungus. Save the world by going vegan.
you cant eat plants ! they are alive too!
@@RussianPlus if you chose to prefer to see it this way you should start eating human bodies. Soon we'll have plenty of them. The rise of mankind had started with cannibalism and it will end with it as well...
I keep asking myself why there are so many people who need to both believe and be told that mankind is a terrible species, and that this planet and countless species are on the verge of destruction. These claims are made so, so frequently, and always, always, always fail to come true. One of the last people you want to believe is someone who's always predicting disaster. It must psychologically satisfy some people to constantly tell people the end is near, or to need to believe someone who tells you that.
Snow crab would like to have a word with you...while they still exist. So many examples all around us. Willful ignorance - can you please do a TED talk on that? You're really, really, really, really good at it...
Mass extinctions occur very often on our planet. They are caused by a recurring natural disaster. These disasters are mentioned in ancient books as the Mahabharata from India and the Popol Vuh from the Maya and others. They tell us about a cycle of seven disasters that separate world eras. Regularly recurring disasters can certainly not been caused by asteroid impacts or volcanic eruptions. The only possible cause can be another celestial body, most likely a planet, that orbits our sun in an eccentric orbit. Then it is near the sun for only a short period and after the crossing it disappears into the universe for a long time. Planet 9 exists, but seems to be invisible. These disasters cause a huge tidal wave of seawater that is pulled over the earth. At the end it covers the earth with a layer of mud, a mix of sand, clay, lime, fossils from sea and land animals and meteors. They also create a cycle of civilizations. To learn much more about the cycle of recurring floods and its timeline, the recreation of civilizations and ancient high technology, read the eBook: "Planet 9 = Nibiru". You can read it nicely on any computer, tablet or smartphone. Search for: invisible nibiru 9
When you use Al Gore as a source, you lost my attention. Yep.
Mr Kirkland, please print your words and leave them for your grandchildren. Your words sadden me. Please reconsider your position. Forget Al Gore; find other sources you trust.
If Trump is president, I'm president too
Al Gore!!! I'm out of here.
Good riddance
Sorry found this talk very boring not really Ted material.
Blah blah
Are you getting rich by scareing people?? Stop it.
