Exactly. People keep going on about how “nature will adapt”. Sure, eventually it probably will. What people don’t really seem to understand is that we should be concerned with rapid climate change because it will make it harder for us to live. There is no logic to ignoring climate change. It would be cheaper for us and better to mitigate it now rather than having to deal with the increasing devastation into the future.
@@newspaperbin6763 Yes actually, Micro plastics are messing with our endocrine systems and mens junk and testosterone are shrinking rapidly with every generation
I remember when I was a kid I read a book and it talked about this shrinking in animals. I was amazed that million years ago there were wolves that was so big it couldn’t fit into a room.
@@thestrongholdsociety No they weren't. Dire wolves are only a little bigger than the largest grey wolves, and most of their dire-ness comes from being more robust. Dinosaur sized wolves never existed
@@TalenkauenTV dire wolves weren’t Dino sized but it depends on what you mean by “Dino sized” considering dinosaurs came in various sizes from micro raptor being tiny to 60 ton sauropods. I mean bears can barely fit in some rooms if you live in a cramp apartment so a direwolf definitely wouldn’t fit either
I’m teaching the importance of Ecology to my students. But in reality, majority of them don’t care about nature tbh. Some of them does and I’m hopeful with them.
Maybe because we aren’t making them study fun to understand and more practical in day to day life. And also because of competition and pressure to pursue specific set of lifestyle in future. This mentality needed to be change.
When I was in school, I was NOT interested in nature unless it was some terrifying creature, like the shark. Beyond that, nature was just not a thing. Now that I'm older, nature is more important as now I understand WAY more things about how interconnected everything is. A teacher of mine once said that he noticed that students often don't care much about history because they don't have much of a history. I think the same concept applies EVERYWHERE. Someone won't be interested in a topic unless they know/understand more about how it connects to other things, which requires a bunch of history to get that understanding.
The lesson i got from a Biology teacher that make me reconsider what climate changes effect to living being Ecosystem provided the great nature, and if its damaged, it’ll eventually recover in certain time. But if something damaged just before the recover is finish, it’ll be shrinking and shrinking more. And that when ecosystem have to do something, the nature itself explodes to a highly damaging things, so that it can start over. And that when we experiencing effect of it, climate changes do faster than it supposed to happen, making the world unbalance and it’s risking living being like plants, animal and human. Climate change is normal, but what most concerning is how it happened so quick over time and we have nothing to do with it before the nature finish to balancing again.
This comment is worthless. What I can try to gather is that you are trying to regurgitate the exact same points from the video. I don't see anything new or any analysis from the video in this comment.
Plasticity means that the characteristic won’t necessarily be passed onto offspring, not that it can’t be! Just a clarification because there are plastic phenotypes and other characteristics which can change and be handed down.
I'd never heard of a physical change during an organism's lifespan that can be passed on! Can you give an example or refer me to a site that give more details about this phenomenon? I wanna know more
@@EIO01 Some affects can be passed on to the next generation if it causes the germ cells to change in some way, I'm not entirely sure of the mechanism behind this,(I recall it has something to do with epigenetics) There's the "Dutch Famine" and "children diabetes" link that might be something interesting for a read.
@@franciscocz8384 Considering how comfortably humanity is, and the ethical problems with Eugenics, there wouldn't be enough environmental pressure to force us to change.
Exactly you get it. The key here is the missing parts are Urban ecology and Novel ecosystems that could actually benefit many of these species to come into new environments. To an evolutionary biologist this is amazing and a key part in understanding things, unfortunately ecologist are highly pessimistic towards things.
Wow - what an interesting effect! Great video as always, Christophe! I might want to go further from here and find out whether there's a similar effect in marine creatures.
@@sfdjk well, yes. English is stupidly inconsistent, sometimes you give plural marking sometimes you don't. So to avoid giving myself a headache, i use words like fishes or persons 🤷🏽♂️🤣
@@thetimelapseguy8 unfortunate more bears=more competition for food, and more contact with humans as the sea ice comes in later and later for the starving bears. Plus the Grizzly’s range is expanding towards Polar Bears, and some wonder if they will compete with each other, or interbreed to create a Polar-Grizzly hybrid that will drive non-hybrid Polar Bears to extinction.
I'm a mother and its sad knowing the earth is in "danger" for my children to live in the future. Our grandchild must be blaming us as a generation who made this.
I understand you but lets not feel too guilty and forget that this is also at the fault of big corporations, who account for more than half of the climate change and carbon foot print. They sadly only care for their money, you can only do your best to raise them to try to do better for the world :)
@@Judexxxxxjjjjj Yes, the main thing we can do to continue destroying what is left of nature is to keep on procreating. But would be parents feel content on saying: I’ll teach all my children and many more grandchildren to be respectful with mother earth and the earth will hopefully become a better place.
Dude, every day lots of animals reach their extinction date. I think that's fascinating how you can in some cases literally point to an exact day or even hour of the end of a species. The earth has had 5 mass-extinctions of life tge last 600M years, now we are in the 6th one called the Holocene extinction. But I don't care.
@@sillycheese301 of course we are. Yet, big corpos are doing the most damage and technically they have the resources to do something better, unlike common people
People who don’t go outside much tend to think that climate change is just hotter days. My dad just went to Alaska and those old fishermen told him this was the first time they had _ever_ seen certain species.
sadly, humans will keep on growing larger, both in terms of population and in weight, at the expense of the animals and the environment edit: I'm not sure if I should have kids now, or is it better to adopt?
@@korakys our population as a whole is still increasing, it's just that the growth rate is slowing Population in the world is currently (2020) *growing at a rate of around 1.05%* per year (down from 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current average population increase is estimated at 81 million people per year.
In simpler terms. Humams are slowly destroying the ecosystem, well that's not how it's supposed to be. I guess we'll witness the end of the world earlier than expected😃
1. buy less clothes/shoes 2. eat/drink less (how about that bottled water?) 3. travel less, don't go on vacation outside your city limits 4. live with your parents, don't buy a new house 5. commute on a bus/metro 6. don't buy a new car or at least find an old one - couple of CO2 grams is nothing compared to pollution created when manufacturing/recycling a car 7. do you really need that new iphone/macbook to watch VOX? What is really depressing is hypocrisy and we cant even do anything about it.
@@Zynthex Dont have good tap watter? Well boil it just like you boil your soup, wait till it’s cold and use some left over glass/plastic bottle to carry with you. Is that normal to have 3-10 shoes? I bought a new pair after finding holes in each of my old ones. Municipality takes care of number of busses on a street depending on number of passengers. Just dont buy a new iphone/macbook, buy used one, use the one you have till its irreparably broken. And so on and so on.. but i get it - finding excuses is so much simpler than putting effort into doing anything thats not comfortable. Even if its for a greater good.
@@arunasjunevicius533 Also, lets collectivally stop buying milk so that industry goes bankrupt. Whether we need meat is debatable, but we surely don't need milk troughout all our lives.

In Hindu mythology there is a book called as *Shreemat Bhagwat Geeta* or short name:- *Geeta* And it is written that over the time the sizes of animals will decrease both genetically or environmentally.... Can't believe it's true....
...no. The Geeta does not say that. You might have a translation that takes too many liberties. There are no such prophecies in the Geeta. That's something you might find in one of the Puranas.
@@salemsaberhagan Then, it must have been a mistake from my end, maybe it is written in any veda, sry i read too much books so I maybe little am confused...
@@Lukky_175 yeah that's sadly a problem a lot of people face when they truly enjoy learning without being too picky about the source. But it starts baseless rumours too. I can say it's not the Geeta because I've read the original text for that. Translations are more art than science so it could very easily be a translation.
You should look up the Pygmy Mammoth on Eons. Great channel it is done by PBS so you know it is well done. In the past a lot of species of animals have been known to shrink or even grow.
Remember doing a study on rodents in S.E Asia... we found a similar conclusion that rodent mass has statistically significant reduction in body mass over the past 3 years. However, interesting observation we found that some rodent samples we took closer to the city are significantly larger than those we took further out - potentially due to the amount of city trash available.
But feminism and climate change are still unrelated. The women's march in LA is not about women, it's people holding signs about climate change, immigration ....
I am not a scientist, but from science I've learned that organic beings has constantly being smaller than earlier generations due to the reduction on oxygen density, but now I see the theory presented on this video contradicting everything without any explanation about why this new theory is more precise than the previous one. I also have learned that correlation doesn't mean causality, so we should be more inquiring before taking anything on internet as true.
Heads up. The calipers in the thumbnail and at the beginning of the video are not drawn/modeled correctly BOTH of the two small "teeth" on the right side of the measuring instrument move when the jaws on the left open. Not just the top tooth on the right side. If that makes sense.
Great video. I only wish it had also addressed the effect on birds of how far fewer insects there are now in the world. I don't mean all of them: I was eated alive this morning when I walked through a swamp. But I love to ask older people (like myself) to estimate how many insects were splattered on the windshield after a longish car trip. They never get it right: NONE, as opposed to many 20 years ago.
It is important to name a rule to be named after a scientist who found a thing which is known to others because the Bergmann's law principle is stated in Vedas, written about 3000 -2000 years prior, which is not written by Bergmann unless he is a time traveller and Sanskrit scolar
Can you provide the exact quotation in Sanskrit. The name of the treatise with adhyaya and sloka number? Don’t send random website links of things written in English. I can understand Sanskrit. So kindly provide the original Sanskrit text with the name of the treatise
Vedas were great but their wisdom was lost. The law was rediscovered again by this scientist and hence known to the world. U may not agree but vedas failed to propagate thier knowledge well.
Not to mention, uh, "Western civilisation" being the one that brought the name into English, and although possible many science was found and stated much earlier in ancient times, it found it hard to survive (dark ages) or become widely known enough for it to be what most people see as the original, as both events of discovery are detached from each other - also living in a society which greatly values 'western achievement,' even if this knowledge was known ages beforehand. Also although common practice is to name it after a creator, this is not a rule, and also is named after things or people said discoverer admires, or some other big scientist, e.g. Avogadro's number was not discovered by Avogadro
@@bernardomercado261 I not against western civilization I am against taking the credit of things for discovering which already exists which is known to others, best example of this is discovery of America which is prior inhabited by millions of people before vasco de Gama came, by doing this you deprived the existence of naive American people, you barking and I don't want to be bitten by you
@@chandlerminh6230I had listen the translation of Vedas from someone I am not in contact this may sound excuse but this is a sad really, I do not want to sound racist but you are probably from South East Asian ancestory which is part of a ancient civilization of people beyond Indus rest you are intelligent enough you will get your answer
Its the same in Indonesia. As the biggest islands nation, our fish is also shrinking. But now... All the fish in the market are smaller than when I was a child.
If this is true for all animals this must also be true for Humans. We might not notice it yet but we mught see shorter humans when the climate warms over the next 1000 years
Last week I visited a rather hot town (it was 39° when I was there) and when walking around I scared a small bird that flew up to a power cord. To my surprise I saw that it was actually an eared pigeon, barely bigger than a sparrow. I looked around and all pigeons I saw in that town were that small
It's interesting that shrinkage happens in birds and reptiles during increased temps, yet, when dinosaurs walked the planet, (I was given the impression at least), it was quite hot on average planet-wide.🤔
great video, would be great to have the links to the cited papers in the video description as well, that would make it easier to look them up (they are freely available via Researchgate or the journal websites)
Evolution doesn’t go 'forward' it only selects traits that make an animal more likely to reproduce successfully. Evolution has no goal. But if it goes on long enough it could be evolution
Evolution isn't directional. It doesn't have any goal to go from say fish to mammal. This would be evolution, where the phenotypes of a population changes over time due to selection pressures.
Not literally forward. I mean, when animals undergone evolution it means that it develops a certain type of traits right? But, what if a chance(is there any?) that developing some kind of traits is the reason that leads a particular species to go extinct? Does it still evolution?
@@jbarquilla995 Traits developing in a species that leads to their Extinction is part of evolution. Some Species going extinct and others surviving is the natural selection pressure that leads to niches for new species. Not trying to say that what is currently happening is a good thing though, we are changing the environment quite quickly and things dying off leads to a marked decrease in genetic diversity. Which leads to environments that are less robust, and these changes are happening really quickly on evolutions timescale.
It's scary to think that this day in age and we still can't manage to put important topics like this first. I don't know where we're gonna be in the next 30 years, this is precisely why I don't want to bring kids into this world but adopt.. I don't know if that's just me but goodness, I will be thinking about this all night, sincerely scares me :'c
The only way people would realize global warming is happening is if their... something else starts shrinking in length and girth, then they'll care....
Agree! These big companies, like the one we are watching this video, used psychological tools to get you hook on watching and coming back for more and more..
It's not related to temperature, but CO2 concentration. More CO2, smaller animals. It has been like that for millions of years. CO2 was at a record low when dinosaurs were around.
I think that the reason behind the fact that martens, shrews and otters are getting bigger bodies is that Bergman rule doesn't apply to long-bodied animals and actually the temperature effect on them is inverted- the higher the temperature, the bigger the long-bodied and warm-blooded animal is. As an example- the biggest otter species lives in Amazon Forest and not in the boreal region
As the buildings gets taller, the animals in nature get smaller. Such a balance must always exist in nature to correct the imbalances done by human unawareness.
I read something about a major warming event 65 million years ago where Earth’s temperature skyrocketed and shrunk at least 99.9% of all species during the time into ashes and a few markings on the ground maybe we can cross examine these two events to find an answer to the current issue
