- Plant pathologist Rachel Warmington argues that we should not overlook fungi, explaining the many ways they can improve our lives, from life saving drugs to getting rid of plastics.
Rachel is the plant pathologist at Cornwall’s award-winning Eden Project, where she is responsible for detection and control of plant diseases, as well as keeping an eye on soil health. She completed a PhD at Warwick University, working on a fungal pathogen that affects more than 400 plant species, for which she was awarded the Marsh Horticultural Science Award in 2013. 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
There are some guys making mushroom surfboards. If they break they don't dump a bunch of styrofoam into the ocean.
Post a link so I can check them out please
That was beautiful. Thank you. Yes, all metazoa is more closely related to Fungi than plants because we are both heterotrophs. It's incredible to see the evolutionary bifurcation of heterotrophic eukaryotes. The way each branch has come to create locomotion always amazes me.
Great message,well spoken, amazing sweet words.... Thank you.
Survival in life requires having a balance of all things.
Thanks Sherlock
great video, I like it and all, thank you TEDx talks
Fungi and bacteria will rock in future
...as they rocked the past.
I like it and all, thank you TEDx talks!!!
How do we know that exactly 93% of fungi species are not known, when we don't know the exact number of fungi species?
We don't know it with 100% certainty, but we can do a very good estimation using a technique called "rarefaction curve". Let me explain. Imagine you and your team of scientist just arrived at a forest that has never been explored and you want to know how many species of fungi live there. The first year you start searching you'll find a lot of species that had not previously been reported, since you are the first ones doing the reporting. The second year you'll find some more new species but you'll also find the same species you already reported. As you keep exploring the forest over the years, your team will start noticing that with each passing year, you'll encounter less and less species that you have never reported before. So you make a plot with "years*number of scientists" on the X axis and "number of species found" on the Y axis. This curve is called a rarefaction curve. What you'll see on your rarefaction curve is that first it grows fast, and then it starts at a certain level. Basically, it's a logarithmic curve that tends towards a certain value on the Y axis (asymptote) but never quite reaches it. Using a regression and some basic calculus, you can make a good estimation of how many species you'll end up finding if you kept exploring for infinite years (assuming no foreign species moves into the forest).
Now, let's say your team used only direct observation as your method of identification, and a new team decides to repeat your exploration using better tools (i.e., metagenomic analysis of soil). Their rarefaction curve will start growing faster, and they might even find species you never saw, but in the end they'll also end with a logarithmic curve with an asymptote in the Y axis.
Now imagine that different teams keep looking for new species using different methods and now you have many rarefaction curves. You'll see that when the curves are extended to infinite years of searching, they'll all end up around a similar value. That value is the predicted maximum number of species. So, if the rarefaction curves say that there should be approximately 100 species in the forest, and you have found 90, you can say that you have found about 90% of the species in the forest. To do the same on a global scale, we take all the rarefaction curves made for all known ecosystems, and we adjust for the percentage of the Earth surface that each ecosystem occupies, we can make a rarefaction curve for the whole planet and thus have a good estimation of how many unknown species are to discover.
@@iluan_ thank you, you now have made me want to learn more about these in maths now
@@iluan_ that was actually very interesting. Thanks for explaining!
I thought of my toe fungus
Thats the parasitic fungi
They secrete enzymes that break the skin in which they digest. Thats why you experience scales, open wounds between your toes etc..
Thank you !
We need more people spreading the word of fungi of all types. Our future depends on it.
As Beauveria bassiana(fungi) is being cultured with sorghum grains and then separately used as as a biopesticides is incredible.
*Being defeated is often a temporary condition. Giving up is what makes it permanent. ;)*
What does this have to do with fungi?
Doesn't make you feel all warm inside, knowing that not a single person in that audience or watching online is going to do anything about this... Life is good.
very important!
Es muy interesantes los artículos y los vídeos , quería pedirles un favor , si es posible subtitular en español los vídeos por favor , muchas gracias .
Permaculture has done a lot to make people understand how vital fungi are. Thank you for this talk.
Great video I like talk about food and all
It is very interesting articles and videos, I wanted to ask you a favor, if it is possible to subtitle in Spanish the videos please, thank you very much.
If you're interested in fungi look up Paul Stamets on TEDx or JRE
Perfectly balanced , like how it should be.
Fungi are cool. Thank.
Parece mesmo excelente este video! Pena que nao tem legenda
Daqui a pouco chega ;)
It's like they're the Earth's microbiome digestive system
Great
The more I watch these the more I find out about how little I know about the world and what society is up to apart from what the media promotes.
Perfect Title thats what i said after watching...Don't forget the Fungi!
Kk your picture shows beautiful fill lips. Results from the fungi?
only one of them is mine but thank you lol 💋
How to forget the fungi when we have mushrooms, toadstools and athlete’s foot?
I hypothesize fungi hold the key to growing new skin tissues!
@ G. Keith Walker,
Hypothecate = Pledge (money) by law to a specific purpose.
Hypothecize = Put (something) forward as a hypothesis.
Methinks that perchance you are confusing these two similar words???
@@budg7525 spell checker wrecker changed it however thsnk you for your input. Now to the point of my comment, no words?
@@gkeith64.
None!! Except to say that you appear to have impressive facial fungi yourself.
Is that your own innovation??? LOL!
Parabéns
People are taught to speak slowly in front of an audience, and I'm here impatiently speeding it up to 1.5x
Its because of the fungi.
2x speed here.
I do this with everybyoutube video lol
@Shaharaj Shihab fair enough
@Shaharaj Shihab You have made a good point, I admit that talking slowly is necessary, especially when english is not everybody's first language. That's why I did not say 'she has to speak faster' but I'm glad I have the option to speed it up for myself on CZcams.
Is still in use the kingdom classification? I thought that dominion one was more accurate ...
If I could have my time over again, perhaps I would study fungi instead of physics.
Welcome Rachel sweetheart love u take care...
fungi great informations
I had athletes foot real bad ... just doing my part.
Parasitic fungi
いつになったらこれが理解にできるようになるかなぁ〜
Magic mushrooms approve
En español por favor :(
I'm a fun guy!
She must have hung out with some FUNgi
👏🏻👏🏻
Big Chungus approves of this video
You’ve heard of elf on the shelf now get ready for
This just seems like random fact after random fact.
🤗🤗🤗🤗
😍
👍👌
He was a FUNGI!
Big Chungus
No
Ladies love me because I'm a fungi.
Great !!!!!!!!!!!@@@@@@@@
This video is sicko mode
I thought of mushrooms....I'm not a scientist I'm sure most of us are not. So your talking to a very few of us. So on that I'm out. Thanks. 👍
*Early squad*
🙄
한국어지원이된다면좋으련만...
*early squad*
I thought it's about the fungi that grows on my foot and around my balls...
Trump, Nova Scotia rocks!
Second
First
I’m just here because I liked the thumbnail. She looked like she had some voluptuous fungi. ;-)
Yes a very attractive healthy woman. LMAO
Ooooooh the fungi!
I cant believe i wasted 12 minutes and 38 seconds on this video. What was the point?
so much opportunity to virtue signal
