I know it's an ad, but is it not false marketing to claim that you can "offset" your carbon footprint? In principle - yes, if one plants enough trees they could potentially suck out the co2 you are emetting, but it requires that those trees grow what, 10-100 years before they have sucked enough carbon out, and then, when the tree dies, another tree should be planted to recapture the co2 which the first tree is re-emitting when rotting. But the reality is that the chance for both the first tree growing for many years, and the planting of the new tree are not guarenteed. MOST importantly, the green house gasses that we emit right now are extremely important, as they contribute to the world reaching certain tipping points, in 8-10 years. The trees being planted now will barely help against that. Of course its good to plant trees - and for many reasosn beyond just co2. But youre not offsetting your carbon footprint right now. Youre hoping that it will be offset in maybe 10, 20 or 30 years. And at that point, it might be too late. Going further than that, we actually need to reduce the amount of carbon emmesions already emitted. Claiming that by just planting some trees every month you can continue to live your life as you have always done with a high carbon footprint is directly misleading and borderline greenwashing.

"Personal carbon footprint" calculators really originated as an ad campaign by fossil fuel companies persuading people concerned about the environment to focus disproportionately on individual choices instead of the corporate actions which are the main drivers of climate change. To stop the ongoing damage we are doing to our climate, we need legislation (at LEAST corrective taxes, possibly more given how late to the issue we are now) restricting the corporate actions that primarily cause climate change, and governments committing themselves to pull support from these sectors and invest in cleaner infrastructure instead, not distraction programs to divert concerned citizens' political energy and money to individual actions that have only a very limited effect in comparison, while business models that involve industrial-scale environmental damage continue to propagate unchecked.
45 QUINTILLION nematodes. That is 'approximate' solely contributed to humans and not including animal population....imagine the number in the universe....like literally TRY to imagine the number that big. We are truly living in scale and are so much smaller than we perceive ourselves to be.
@@LaBronne >we are so much smaller than we perceive ourselves to be That would be a fair point if this was a video on the universes scale but it isn't, I think you're trying to hint at the fact our population is small but the fact that this many exist proves that we are way larger than we think. The smallest thing we know is so much more orders of magnitude smaller than us than the universe is larger, the numbers say we are actually the large things.
@@shill2920 You THINK that I meant we are bigger than we perceive ourselves to be....even though my words explicitly say "we are smaller..." 🤣 says a lot about your train of thought. If we compared your brain to a raisin, would that not be scaling because the sizes are too similar? any scaling ratio is a fair comparison.
Small correction from a C. Elegans researcher here: not sure where the “over a thousand eggs per day” came from? The standard estimate is 4-10 per hour (so 250 a day). It’s been pretty consistent with my experience as well. Not sure that I can post with links but WormBook has that and just about anything else on C.elegans basics you could want.
Can I just say - first, that it's awesome of you to offer up this correction because it's damn interesting in its way (also very cool that you research these!) Second - how great is it that there is something called WormBook, which makes me think of FaceBook for the nematode world... I'm sure that's not at all how it works or what it's for but it is nonetheless HIGHLY amusing!
@@alaeevolare5395 there are several brands that sell beneficial nematodes for pest control. A quick google search should have some pop up, and it can be possible to select based on needs, some can deal with slugs and snails for example or you can get a 'broad spectrum' mix that has several species that can tackle many common pests.
When I was studying worm compost micro-ecosystems, we had one ecosystem sample where a large Eisenia Fetida earthworm died of natural causes, and its body provided a sudden food influx into the ecosystem. The nematodes quickly gobbled it up, and exploded in population. Their numbers became high enough that they were able to start attacking and kill the other earthworms. This turned into a positive feedback loop where more nematodes -> more dead earthworms -> more nematodes. In just a couple of days, the nematodes killed all the earthworms, and collapsed the ecosystem. Their population quickly died off as well, because they ate through their entire food supply and no longer had a stable ecosystem to exist in. In just a couple days that sample went from very lively to completely dead. I should make a video on this some day. I still have the original footage of the nematode/earthworm battle. Great video as always Microcosmos team! I'm consistently impressed with the quality of James' footage. I'm super curious how you export your edited videos such that it gets the RUclips video compression algorithm to play nicely. I see many microscope RUclipsr's videos with significant compression artefacts, especially when there is motion. Edit: Thank you all for the overwhelming rally for this video. It has been made and uploaded!
I remember the first time I saw a nematode. It was during a plant cell biology lab and I was looking at some plant cells when this (relatively) gigantic worm squiggled into view in my microscope. I had so much fun looking at it moving about that my lab partner had to ask me to focus on the actual task at hand
If you guys ever run out of content, dont worry..... we will always be fascinated even if you do old content from scratch..... I think it is impossible to get bored watching the Microcosmos and listening to you explain many things

Hello my name is Caio, I'm Brazilian and I dream of one day becoming a microbiologist. today will be the start for the exam results to see if i managed to get into college here in my country. Wish me luck, it means a lot.
Can you please ask the master of microscopes to order some "beneficial" nematodes (against fungus gnats) to show how the are sent (the media, if it's mainly eggs are larvae etc)? I think every plant keeper sooner or later faces fungus gnats, so many know of nematodes as a weapon out of the microcosmos and would love to see a video narrated from this perspective.
Yes! Fungus gnats fly through my window at night from the garden downstairs and harass me while I do schoolwork. Beneficial nematodes were what gave me peace and I’d love to see them in a video
I'd love to see that too. Along with gnats, beneficial nematodes got the sand fleas OUT of my lawn for good. Also did a number on one small plot I tried growing crops but assorted cutworms and other grubs would eat them. Nematodes to the rescue. Good guys for sure. At least as far as eating dirt pests.
Pro tip to anyone that wants to REALLY reduce their carbon footprint, write to the DOE and tell them that you support innovative nuclear reactors that inherently reprocess their waste on site. Nuclear is zero carbon.
look at any animal, and apart from a few appendages, and organs they are still essentially a worm. In on the one end, out the other. It's a very successful strategy.
Thank you so much........now I feel better about having named my son Nematode.......his twin sister Chlamydia, however, still requires some vindication.
Watching your videos back to back and just reminded of something. As an avid anime lover I remember a series called Mushi-shi. It describes "Mushi" are some of the primitive life forms, mostly invisible to naked eye and often can be seen as supernatural because of their nature which are very very different from humans. These videos look like these organisms are Mushi.
In horticulture we not only fight nematodes as creatures causing harm to our plants but also use them (different species of course) to figtht other troublesome organisms like insect larvea
Hi, I'm really curious as to how a nematode gets "stuck" inside an amoeba in the first place. Is the amoeba attempting to phagocytose the nematode? If yes, is it while the nematode is still alive? (As none of the stuck nematodes were moving) Also, the carbon footprint is a pretty evil tool by megacorporations to shift blame away from themselves and onto the public. I do not claim to know much about Wren, but the aforementioned megacorporations are responsible for the bulk of all pollution. Businesses offering carbon offsets like Wren may make you and I feel good about our contributions to the planet, but in the grand scheme of things, said contributions are a drop in the ocean. Excellent video, as always!
It's not an amoeba, but rather the uninhabited silicate shell (test) of a testate amoeba, perhaps a Euglypha tuberculata or similar. It seems that both clips are of the same nematode, judging by the stuff stuck to the shell. Poor little guy probably got stuck trying to find food in there and wedged itself in when trying to get out.
A raid boss in WoW's Pandaria expansion called Elegon looks very similar. It's blue and transparent. Fair assumption that the name was taken from C elegans
Do you know what would be nice? A complete anatomical explanation of the creatures presented in the videos, so we can understand all the visual information that comes with the amplified images. I am very curious about the metabolism of such little creatures.
Too cool! I’ve used these little doods to make mature ant hills move house ! I felt bad but it’s better than Raid. Using nature to fight nature makes more sense.thanks, team xo

Dr. Cobb's full quote on the dominance of Nematodes is both haunting and beautiful, which is difficult to do within a scientific paper, doubly so when its about a lowly microscopic worm. 'In short, if all the matter in the universe except the nematodes were swept away, our world would still be dimly recognizable, and if, as disembodied spirits, we could then investigate it, we should find its mountains, hills, vales, rivers, lakes, and oceans represented by a film of nematodes. The location of towns would be decipherable since, for every massing of human beings, there would be a corresponding massing of certain nematodes. Trees would still stand in ghostly rows representing our streets and highways. The location of the various plants and animals would still be decipherable, and, had we sufficient knowledge, in many cases even their species could be determined by an examination of their erstwhile nematode parasites...'
aahhhh the DIC microscope makes them SO PRETTY!! (tho i like the brightfield colors as well) I've been waiting to binge watch eps. cause i'm missing using my microscope sooo muuuuch! I'm sure there are microbes in Msla right now, but it's cold and i'm not going hunting just yet :D i love getting to watch several new eps in a row :)
Thanks for another of your excellent presentations, but I wish you had said a little more about the positive aspects of the nematode. Their ability to destroy or deplete invasive insect populations by eating their eggs, their fondness for eating dangerous bacteria and their relationships with plant roots that assist the plants in multiple ways.
in mijn bibliotheek vele mooie sweties van vele van deze ook voor mij enorm interessante nieuwe dieren die hoewel ze klein zijn veel nieuwe ontdekkingen op natuurkundig gebied zullen bewerkstelligen èn omdat het klimaat steeds weer opnieuw wijzigt zal het erg interessant zijn te kijken hoe ze zich verdedigen tegen al dit soort veranderingen .. veel plezier ermee ..

If they cover that I really hope they cover the much more complicated ecological relationship between H. Pylori and hominids as it has revealed that the the relationship is not actually one of a pure pathology since there is also evidence they perform important ecological roles within the gut microflora which play a role in regulating metabolism and particularly the immune system. In effect H. Pylori appears to really be an essential comensual organism which when out of balance can turn pathogenic. Prior to the use of antibiotics *all humans* and our ancestors before that had H. Pylori and had coevolved with them for millions of years the microbes passed from parent to child. Then some guy comes along desperate to prove they have a role in pathology, which they do under certain circumstances, and gets the medical community to treat them as pathogens resulting in a large uptick in the rate of autoimmune disorders and allergies among "cured" populations. "Contrary, there are numerous reports suggesting that H. pylori is an evolutionary "friend" of humans, rather than a "foe," because it can protect the host against gastroesophageal and inflammatory bowel diseases as well as certain allergies such as asthma (Blaser, 2010;Jessurun, 2021)" In effect there is growing evidence that the harm of wiping out H. pylori is significantly greater than the risk of it turning pathogenic. Worse as naturally H. pylori was passed from parent to child resulting in a coevolutionary dependence, thus once you wipe out a familial strain its gone which turns out to be significant as all ethnic communities H. pylori strains are/were genetically unique. The absence of native H. pylori strains then leaves a vacant niche in the gut microbiota which can be colonized by usually much more virulent strains so In effect we have selected for invasive antibiotic resistant strains much more likely to cause pathology than indigenous strains. H. pylori "treatment" is thus a modern medical disaster which is only getting worse and since the journal articles on this field of biology are locked behind paywalls public awareness of the situation remains poor.

You can go ahead and call this nematode propaganda, but at least when the nematodes were in charge the trains ran on time!
Correction... you said nematodes are measured in MILImeters... you meant to say micrometers. (at around 01:00)
another example of why you shouldn't click on journey to micro while you're eating
Is the voice Hank green??
Nightmares can be considered art as well depending on your frame of reference.
I bought nematodes to kill my fungus gnats. I don't have fungus gnats anymore.
Love them.
Certain nematodes do a fine job on larvae of Japanese Beatles.
The music is a lot quieter than usual.
I just joined the patreon because i want my 57B nematodes
Ever heard of Nano-oil? Could you look at it under a microscope and see if you can see the carbon bearings?
Oh... nematodes
3:20 ...DRAMATIC PAUSE! 👍🏻
Speaking of scientists infecting themselves, helicobacter would be fascinating to see in one of these videos. No idea how you'd get them though...
If they cover that I really hope they cover the much more complicated ecological relationship between H. Pylori and hominids as it has revealed that the the relationship is not actually one of a pure pathology since there is also evidence they perform important ecological roles within the gut microflora which play a role in regulating metabolism and particularly the immune system. In effect H. Pylori appears to really be an essential comensual organism which when out of balance can turn pathogenic. Prior to the use of antibiotics *all humans* and our ancestors before that had H. Pylori and had coevolved with them for millions of years the microbes passed from parent to child. Then some guy comes along desperate to prove they have a role in pathology, which they do under certain circumstances, and gets the medical community to treat them as pathogens resulting in a large uptick in the rate of autoimmune disorders and allergies among "cured" populations.
"Contrary, there are numerous reports suggesting that H. pylori is an evolutionary "friend" of humans, rather than a "foe," because it can protect the host against gastroesophageal and inflammatory bowel diseases as well as certain allergies such as asthma (Blaser, 2010;Jessurun, 2021)"
In effect there is growing evidence that the harm of wiping out H. pylori is significantly greater than the risk of it turning pathogenic. Worse as naturally H. pylori was passed from parent to child resulting in a coevolutionary dependence, thus once you wipe out a familial strain its gone which turns out to be significant as all ethnic communities H. pylori strains are/were genetically unique.
The absence of native H. pylori strains then leaves a vacant niche in the gut microbiota which can be colonized by usually much more virulent strains so In effect we have selected for invasive antibiotic resistant strains much more likely to cause pathology than indigenous strains. H. pylori "treatment" is thus a modern medical disaster which is only getting worse and since the journal articles on this field of biology are locked behind paywalls public awareness of the situation remains poor.
