- Explore how the technology of gene drives could lead to the eradication of mosquitoes and what that could mean for our ecosystems.
--
Mosquitoes are responsible for more human deaths every year than any other animal, but very few of the 3,500 mosquito species actually transmit deadly diseases to humans. Scientists have been conducting experiments using engineered technologies called gene drives that could theoretically get rid of the most lethal mosquitoes. So, should we eradicate these pesky insects? Talya Hackett investigates.

We are already killing off far more important and special animals and destroying our world the only good thing they do is keep down certain pests like in the undeveloped countries!

Yooo nice pfp!

I have no ethical dilemma about this: yes
YES
AGREED
GOOD ANSWER
Agreed!!!
I vote yes too.
Mosquitoes cause so much suffering and death. It would be unethical to let people suffer while we have a solution.
We do not have a solution
Have we watched the same video?
We have watched through different eyes. We may have a weapon, but the solution is not present until all the risks are accounted for.
Its a good thing to see people are not taking rash decisions with the fragile equilibrium of our planet. I hope this tool becomes the solution you are hoping for, but all measures need to be taken for once, to be certain that 'good intentions' won't become 'grand disasters' for our planet.
I saw my uncle developing celebral malaria.. he died a week later... if there is a way to simply end these creatures they must just do so without hesitation 😭
@@joekrater3364 so if people hate sharks and someone says that is no excuse to commit genoice they should have been send to be bitten by sharks?
@@goldenhorse4823 Yes.
@@goldenhorse4823comparing sharks and mosquitoes like this is not logical. Mainly because sharks are only a problem if we are the ones invading their space. In most cases sharks aren't even a threat to humans. Whoever might hate sharks doesn't have to constantly deal with the threat of a shark attack. Mosquitoes on the other hand are invasive pests. Even if you don't bother with them, they will definitely bother you. Last time I checked, sharks don't cause diseases like Malaria or Dengue.
@@goldenhorse4823 a more accurate comparison would be with termites or ants
@@goldenhorse4823 sharks don't actively look for humans to go and eat, maybe if you asked a seal, he'd understand your comparison 😂

kill em all
yepp
my answer after 3000 years ......YES!!!!
I live in a tropical state, and mosquitoes are a big problem. you can have hundreds of them in your house at night, and hear a constant loud buzzing everywhere. I ask myself, there is no consequence bad enough to eradicating them other than possibly having more mosquitoes.
i think so too. it would affect only a couple of species, but eliminate several of the diseases with the highest body count in our modern world. genetically sterilising these species would probably also be a better option than hoping that medication becomes widely available and affordable.
especially since mosquito population will probably keep increasing and even spreading to colder areas due to climate change.
@@atlas956 Don't need to tell me twice. I caught some of their diseases before, and now I attract them like crazy. I actually have to stay fully covered at home and sleep under a mosquito net, it's terrible.
mosquitos is our natural enemies, they need to be burned 🔥
@@TheBosama Believe me, I don't stay here because I love the place too much lol
@@atlas956 issue is it won’t just affect a few species

This should be used on not only the deadly Mosquitoes. It should also be used on bed bugs, Ticks, and any other insect that poses a threat to humans due to their willingness to bite us and subsequently pass on deadly pathogens.
Their bites aren't gaurunteed to be fatal.
@@sachinraghavan4556
eating expired food isn’t guaranteed to be fatal. You still shouldn’t do it.
well bed bugs don’t actually carry diseases for humans, kinda why people haven’t been researching a way to exterminate them properly
What’s stopping people from turning it into something worse that kills all insects indiscriminately, not intentionally even, by accident? What should be the regulation on such a technology-who should make the call when this is used or not?
there are probably concerns regarding food chains for other animals
It's not much of a dilemma anymore. The damage we do trying to control mosquitos every year is insane, removing them from the food chain would be relatively harmless. Every study I've seen on this in the past 10 years has come to that same conclusion
If we kill them with gene drive we won't need to damage anything with pesticides.
Every human made disaster started with us thinking that "there's no harm"
It still is very much a dilemma! Ecosystems are insanely complex. Mosquitoes play very important roles both in aquatic and terrestrial ecosystems, erasing them could have have disastrous consequences. Making mosquitoes immune to mosquito-borne diseases without affecting their populations is a far more promising approach.
@@seb0rn739 more disastrous than using general insecticides against them, thereby killing other insects in the process, as is common now?
Not harmless. The human population would grow and there are already too many of us.
As a mosquito magnet during summer in Buenos Aires I can firmly say my empathy for mosquitoes is absolutely exhausted and I see it as a small sacrifice if getting rid of mosquitoes means the extinction of nine tenths of fauna on earth. In fact while writing this comment I was bitten by a mosquito
😂😂😂
Loooooool ikr
I was bitten by one while reading this comment. And so, i concur

I concur, you guys can blame me. I'm sick of these pest.
YES!!! Dengue is so serious. Nearly lost my mom to it and there’s no treatment. Prevention is nearly impossible because you keep your house without still water, but your neighbors don’t. You get infected anyway
If you live in a nation where the population can't cooperate then you don't have a government who can implement an effective strategy either anyway.
@@SevenTheMisgiven yes. It’s a very complex issue. People don’t do their part. It’s awful.
@@SevenTheMisgiven so basically no Nation on Earth?
@@ldawg7117 Where I am from I can come up with a lot of examples. Scandinavia, Japan, Korea.
@@SevenTheMisgiven but those countries don’t have most mosquito-borne diseases, do they? Dengue, Zika and Chikungunya which is transmitted by the Aedes aegypti live only on the tropics from what I know. Unless they’ve evolved somehow to live in colder climates, which I think they will do someday and with climate change.
I'm in Florida this program was implemented few years back. I can tell you one thing mosquito's are 99% gone. It used to be unbearable to go outdoors without being swarmed today I see none at all.

I live in NW Florida and my house gets apocalyptic numbers of mosquitos. Our summer months are when we have to lock ourselves in our house or rush out the door through the swarm to get to the car and leave. We don’t get to do anything outside at our house.
Need to be implemented imeediately. Have had malaria loads of times in my childhood till my family moved on to a new location where the mosquitos were less but are still there till day. Unable to sleep at night sometimes due to all that buzzing going on around my ears
I live in west Africa. To not have to fight malaria and swallow anti malaria tabs multiple times every year would be so awesome😭
What infuriates me most about this ethical dilemma is the thought that the people most affected by mosquitoes not having the final say in the matter. Let the widows that have endured restless nights due to the hands of these vermin have a voice, not some naysayer from the northern-hemisphere preaching fairytale
Put high quality mosquito traps one per acre, and dont have standing non moving water.

@@seb0rn739 We already killed some animal species, so why not mosquitos too?
¯\_(ツ)_/¯
Remember that Mao Tse tung once implemented a program to eradicate sparrows population because he believed that sparrows are pests that only eat crop grains. Once the sparrows were eradicated, the locusts population suddenly boomed and destroyed the harvests, contributing the cause of Chinese great famine of 1958 . Who knows how eradicating mosquitos would backfire in some way or other?
@@imadearadea3417 while I understand where you're coming from, MZD's order to eradicate sparrows was an uneducated decision, it was included in the "remove four pests campaign" which mosquitoes, rats, flies are also included, but only sparrows were severely affected. Sparrows don't make ppl sick and kill ppl like mosquitoes do. And birds have been a pest since dawn of agriculture, but I doubt normal ppl would go "hmmmm, let's make a species extinct because they make our work hard but they don't actually transfer diseases"
During that era, ppl were also encouraged to sell iron to the government, there are cases where ppl melted their perfectly good pot to sell and ended up less than what they've provided. The iron produce were also terrible so it's not surprising that a lot of decisions back then were not well thought of
For mosquitoes tho, they caused too much harm to human's health, and they are proposing only to eradicate the species that carry diseases. I'm from Malaysia and dengue is something that we actively worry about if it's too warm and there's too much rain (all the time). My father and sister both had it before and they both ended up in hospital, thank God for them it wasn't lethal, but there are many who are not as lucky. Since they're still testing and are actively thinking about the could be consequences, it's a good sign and hope that there's a outcome that has more positives than negatives
These don't seem like ethical problems as much as rhey are merely strategic evaluations. The video does not question whether the end goal should be pursued, but rather discusses the merits of a particular technique in achieving that goal as well as the risks involved.
As much as I hate mosquitoes, history has shown us that every time we mess with something like this to “fix” something, we tend to make it worse. In the USA we intentionally introduced starlings, Himalayan blackberries, and kudzu, and now there’s nothing we can do to stop them.
My only concern before and after this video is. Why haven't we done this already ?
It's because of the pathetic state of the academic world who likes to overthink and overreact. There is NO DOWNSIDES to the population collapse of all mosquitoes. It's not like there are animals in which their diet is exclusively mosquitoes
The answer?
It's really hard to deliberately kill one specific species that is so wide spread
@@MetronaJ And it gets even harder knowing that life finds a way. One miscalculation could lead to a new generation of surviving mega bugs.
It could go off in an unexpected way.
Whole ecosystems could get destroyed.
It might make everything worse
Its not an easy decision, once you kill a species , it will never come back.
I understand the concerns on the food web, but if we can eradicate mosquitoes with only impacting 2 or 3 species, we should take that risk in my opinion but obviously experts can reach a better risk-assessed position.
Yeah. I mean there's the "immune to the pathogens that cause the diseases" option.
@@rvat2003 I know but mosquitoes are just too annoying 😅
But what if impacting those 2 or 3 species have huge consequences on the environment? Then it may not be worth the risk
@pices is correct here. Ecosystems are systems in which almost all pieces are in some way connected. Impacting one species may at first only impact those few species that directly rely on them, but then those that rely on those few will be indirectly impacted, then any that relied on those ones will be, and so on. That can in some cases potentially continue until the existing ecosystem collapses, which is why it's crucial to asses the impact of a species before taking action that might affect it's population.
It's often very hard to impact just a few species, so when there are other options (like immunity rather than elimination) those are generally the safest thing to pursue. It's also important to consider that humans, especially those in non-industrialized areas, also rely on the ecosystems they live in to at least some degree. So destabilizing them can have consequences on us as well.
Not worth the risk. The food chain and ecosystem are actually extremely vulnerable and removing even one species could have dire consequences. It’s better to remove the disease from the mosquitos rather than the mosquitos.
I have a friend from school that encircled his property with bat-houses.
Going over there in summer used to be like donating blood, but now I barely get stuck.
Shame that it wouldn't be so effective with ticks. In my region they carry a variety of life ending diseases. Makes you paranoid every time you have to check for them after visiting a forrest since they are so incredibly small. At least it easy to avoid them completely.
The sterile insect technique is already being applied in the continent! In Ecuador it is for Aedes Aegypti, vector of dengue and yellow fever. Cuba, Argentina, etc are on it too since 2020.
Dengue almost killed me for 10 days lol 105 fever in 110 degree weather . how fun was vacation for me
bug nets and essential oil repellent work, and have always worked. There is no reason to try and modify or kill billions of organisms that are a pilar of the foodchain for THOUSANDS of other species.
From what I heard, mosquito populations quickly bounced back after a quick population drop?
@@thewingedhussar4188 In Singapore, yes.
GOOD
i hope that one day i'll be able to regale my grandchildren with tales of these "things" we used to have back in my day called "mosquitoes"....and they'll be like "mosq-WHAT?"
"Toes of mosqui kids" 😆
Are those little creatures that you can find in a mosque? Why are they called that?
Nothing has caused me more suffering in this world than mosquitoes, i will always say yes
Around 2-5% of people who have ever lived died to malaria. Environmental effects from eradicating mosquitos would happen but studies are pointing towards them not being catastrophic. I would say it is very much worth it
My level of agreement with eradicating deadly mosquitoes after watching the video has gone up to 200%, thank you very much Ted-Ed 😂
Ethical dilemma series is something else: a multidisciplinary, intersection, crisscross and whatnot of various subjects beautifully wrapped into a single video.
You perfectly described it
@@_.nastou._ thank you!
Does the potential consequences make this more of an ethical issue? Mouthwash and hand sanitizers kill microbes so what isn't an ethical dilemma...
mosquitoes ≠ ethics. just slap it on sight
Theres no dilemma here. 150 different species go extinct per year, and Theres no apocalypse consequence happening.
If you really want be cautious(still dont see why but ok), then target only Malaria/Dengue and let the other species fill the void.
Stop having fear and Lets save people!
I have a severe case of skeeter syndrome, which means that when a mosquito bites me, I have a strong, long-lasting allergic reaction that causes the affected limb to swell significantly. Additionally, certain blood types attract mosquitoes more, and I have one of those types. As a result, it is torture for me to go outside in the evening when mosquitoes are around.
My initial reaction would be: yes.
Deciding whether or not to get rid of mosquitoes is a tough question. I assume there would be enough alternative food sources for them, but I wonder if altering mosquito perhaps affects the saliva that could unintentionally create problems for other creatures. It's a complex issue.
I recently read an artice about those mutaded mosquitos in the wild. Apparently researchers have already released some of those mutant mosquitos. However according to that article the mosquitos know when a member of their spicies has mutated and will actively avoid them in their quest to mate.
Eventually, they won't find anyone 🙂
As someone who lives in tropical..
Y E S
Make them all species extinct I don’t care anymore 😩😭😭😭😭
A world without mosquitoes would be heaven on Earth, let's be real. Those summer nights without having to worry about them and constantly swatting around would be so much more relaxing.
However, they are a big source of food for bats, fish, reptiles/amphibians, etc.
Ideally, there would be some way to have them stop targeting humans all together rather than wiping them out, but I doubt there's any way to modify their genes properly for something that specific.
As long as we could find a way to fill in the gap that comes from their loss to keep other animals fed, then I say wipe'm out, lol
Other mosquitoes would fill the niche.
So trueee
I do believe that experiments were done with genetically modified mosquitoes that do not feed on human blood.
Ecosystems are insanely complex. Mosquitoes play very important roles both in aquatic and terrestrial ecosystems, erasing them could have have disastrous consequences. Making mosquitoes immune to mosquito-borne diseases without affecting their populations is a far more promising approach.
They aren't the only source of food for these creatures. The world will move on. People are really out here believing that the world is dependent on mosquitoes when really it's the other way round.
My biggest concern would be the wider ecological impactof removing the mosquitoes however if it's only a particular breed then I imagine the population level of less harmful needs will increase and replace their numbers rather than there suddenly being a gap in the food chain.
i think as long as we keep questioning things like this, we can do stuff like this while not becoming unethical
but if we don't choose an answer, we wouldn't get anywhere, even in the past, we wouldn't have cars, a/c, some medicines, many many things
this video is framed around getting rid of mosquitoes as a complex ethical question, but the only concrete questions brought up are food web related questions that effectively boil down to logistical concerns. I don't really see asking questions about second and third order effects of a course of action to be ethics questions at all. the real ethical questions come after the consequences have been established and the question then becomes a comparison between action versus inaction and the consequences of both options weighed against one another.
I thought food web related questions = potentially affecting livelihood / continued existence of animals, plants etc. As well as possibility of giving rise to other harmful species. Not just human logistical concerns?
@@TheDreamLeaf I might have phrased it confusingly, but I don't mean human logistical concerns. I mean the "logistics" of the food web and how it operates as it stands. But my point still stands: questions of "if we do X, will Y happen?" is not an ethical question, it's trying to find out what the consequences of an action will be. the ethical questions come later, when the future consequences are known (for the most part) and the question becomes "if we do X, Y will happen. if we don't, Z will happen. should we do X?"
@@burnin8able Ahhhh. Totally get you now, and I agree
as if there's no other insects to feed its predators.... what a redundant argument, they're playing with our minds.
@@greendsnow I know you don't want to hear this, but that right there is some SEVERE armchair scientist behavior. feeling out the intricacies of a decision this impactful is hugely important work. I was pointing out how we haven't gotten far enough into the research for the questions being asked to qualify as ethics questions specifically. the questions being asked are not lesser as a result, just of a different nature.
This is for sure going to happen we should start planning for any consequences.
Oh I'm sure some fools will try it eventually and end up in an even worse situation. just like every other time humans have messed with nature like this.
Mosquitoes are pollinators, which could impact food supply
@@Zavult Humans have never before messed with nature _like this._ This is a completely different level. Way more precise, way more quickly, way more deliberate, but also way more conscious than ever before. We're doing our homework this time. But that doesn't prevent the feat from being deliberate eradication.
@@lonestarr1490 and what if it's deliberate annihilation? As a Nigerian f em all
@@lonestarr1490 every generation since thee industrial revolution thought they were smarter then there forefathers. they thought they had done their homework too and could manipulate nature with out consequence. we all know where that line of thinking has gotten us! The fact that they are even considering it is proof they are infected with the same inherited idiocy!
I’ve thought of this since I was a kid. And after 30 years of pondering and thinking hard, I say - YES!!
If there were a way to get the whole planet to work together for one purpose, that purpose would definitely be to defeat the mosquito.
As someone who just recovered from malaria, I just want to know how permanent it is 😅
Short answer: Yes.
Long answer: Yes, but actually yes.
Well, the quotation in the beginning is hilarious yet insightful.
I hoped the video talked more about the effects of getting rid of mosquitos.
depends on what eats mosquitoes and what other food sources they have
mosquitoes are not a main source of food for any animal
@@joannexdd5628 There are quite a few birds, spiders, bats and fish that have mosquitoes as a main food source. (not the only food source though that I'm aware of)
@@erik2602 give me the names of these species then
@@joannexdd5628 Many mosquitoes are polinators
@@joannexdd5628 if they contributed nothing to the ecosystem they wouldn't be there in the first place. It would be a waste for organisms to not adapt to eat mosquitoes when they aren't even poisonous, and they have to eat, taking blood is only for their offspring but they are pollinators, its possible there are even plants that rely exclusively on mosquitoes to pollinate them. Additionally, don't forget they have a larval stage, its not just birds and other insects that eat them, they can be critical sources of food for fish. You shouldnt be giving out infomation like "mosquitoes are not a main source of food for any animal" when you don't even know this. You know theres a mosquito fish(litterally called mosquito fish) that eats mosquito larvae?
With their high birthrate, I fear that mosquitoes might adopt or even develop resistance to any eradication method. Never underestimate the power of evolution.
they still die from being slapped and electrocuted
No, unless a mutation reaccures to prevent male only offspring it wont go away. To explain why, it's how people still have fingers and how blue eyes/gingers/Albinoism etc spread and remained in the gene pool.
Unlikely
R u saying life finds away
for a second I thought u meant mosquitoes might literally start adopting children xD
I feel that it would make more sense to modify mosquitoes to be less likely to bite humans.
One time I had a really bad day, come midnight I'm trying to sleep but can't because of Mosquitoes buzzing and biting me which lead to itching. This went on for around 2 hours until I had a breakdown and literally cried myself to sleep since then I've always hated Mosquitoes.
This wouldn't target every species of mosquitoes, just a particular one that spreads malaria
The animations in TED-Ed videos are always top notch, but this one especially! Simple, yet intricate and beautiful!
This seems like an open-shut case to me.
The end goal isn't to destroy all mosquitos, but to eliminate those species that carry dangerous diseases. For every species that feeds on humans, there's 10+ that don't. This means that the species driven extinct by this are entirely replaceable, and even if they weren't, something tells me that the ecosystem would be fine. If the ecosystem collapses from just the loss of a small amount of mosquito species and we extend that logic to other species then we should be well past the point of no return already, given how amphibians are doing.
This is entirely ignoring that the reason we're doing this is not just because mosquitoes are annoying. A million people die each year from mosquito borne illnesses. If it were on the level of sharks, where 10-20 people die each year, then I could at least understand the logic, however callous it may be, but I get the feeling people don't entirely understand the meaning of that number.
1 MILLION.
This is not a freak incident we're talking about here, like with most animal-related deaths. This is a serious, widespread issue that routinely kills a million people, and seriously injures or disfigures far more. It is infuriating to see people pass off that number of deaths like it doesn't matter, and then start yammering on about how bird species number #2467 might suffer minor issues with adjusting to a slightly reduced palate. We have an opportunity to save millions of lives with this, and seeing people squander it because some troglodytes heard the word "genetically modified" and went "Unga bunga me no likey" makes me want to commit violence.
"Yeah, but they were so preoccupied with whether or not they could that they didn't stop to think if they should!"
One thing I’ve learned is that nature will fill the gaps. It will not destroy the ecosystem. It just may fix itself in a way that isn’t beneficial or even bad for humans
The many forms make nature resilient but just because this resilience exists doesn't mean that we should get rid of the mosquitos. It's just human arrogance. Our ancestors would look back on our barbarity and weep, that we demanded what is just for humanity qua what is unjust for non-humanity. We should be guardians of all life including the mosquito.
Ah! As I get older I notice how shittier and shittier scientists and the sciences get.
We extincted so many animals already (intentional or not) and I don't see the world falling apart from it, and these scientists draw the line at mosquito... Like "ayo, wiping species of mosquito out. That eff up!" LOL
Dont care
@@ShirokumaSama I was about to make this same point
Nature is not a conscious thing
I live in an area infested with Eastern equine encephalitis and when I was smaller I witnessed a horse from the nearby stable dying within days of getting bit. Unbelievably scary, especially when there is no easy way to be cured if a human is bitten
In places where intensive mosquito control techniques were used, we found that mosquitoes do perform pollination, but when they are gone, pollination is largely unaffected (because other insects or mechanisms fill the small gaps left). They are also replaceable in the food chain.
So the ecological downside to genocide of all biting mosquitoes is zero, or close to it.
The question of whether the gene drive would cross species to other mosquitoes, the mosquito genocides which have been done chemically or mechanically also found that elimination of the entire class of insect didn't have a huge impact. There are generally lots of competing organisms for the small space mosquitoes exist in, so if the entire class was gone, other species would fill in, and no long term effect would be felt.
The downsides are relatively small, and it would save many lives.
My aunts husband got paralyzed by dengue fever. He is a fairly old man around 50 and my aunt said he cried every morning. Maybe this will prevent other things like this from happening again.
We can at least remove them from areas where they are invasive like Hawaii. Also I don’t think that there is a huge risk of accidentally wiping them out if done carefully since they have short lifespans, quick reproductive cycles and don’t typically travel large distances
They are invasive all over the world ...except some parts of africa wwhere they spread globally
If that is true and they aren’t naturally apart of that ecosystem I really don’t feel bad about exterminating them.
@@jfhucka1 only 7-8 species bite humans out of 1000's , all of those 7-8 mosquito species are invasive species, thir removal will benefit native mosquito species
@@jfhucka1 yes all 7-8 disease vector mosquitoes are all invasive species, all over the world. Most spread from few regions in africa throughout the world. Infact they outcompete native mosquitoes and thrive only in areas of human habitation...there are approx 2500 species and only 7-8 of them are invasive species and human disease vectors
I am confused as to why this is such a heated question when, if this were in a more developed part of the world (change the script and say those are Americans dying from these diseases) then there would be no hesitation to solve this problem ASAP, especially when the only argument is it *might* disrupt the ecosystem by removing a species of deadly mosquito from the food web (assuming we went with the population collapse strategy)
well due to climate change and whatnot, mosquito diseases are spreading further outside the tropics and deeper into temperate land, like USA and Australia have seen more outbreaks of tropical diseases. give it time haha
I love how the idea we came up with to get rid of mosquitoes is basically the same thing that happened to the Krogan in Mass Effect
How is this even a point of contention? No more mosquitoes
My heart says absolutely, but they are so prevalent in nature and have been for millions of years that they are a part of our ecosystem so idk.
there'es literally a thousand other mosquitoes to fill their empty niche. From a fairly educated guess I don't think it's gonna be a big deal, ANNND Even if there are ecological consequences we can always re-introduce them if we have to. Unlike Cane Frogs, Rats, and other invasive species this is legitimately a pandora's box that we can put the lid back on if we have to.
Their prevalence in "nature" is near human settlements, like pigeons, rats and stray cats/dogs. They've been "imported" from their ancestral habitats along human migrations and trade routes, evolving with us. Without their former natural pressures to keep their populations to a minimum, they rapidily dominate warm urban and suburban areas. Killing A. aegypti to extinction wouldn't distabilize natural ecosystems.
just slap them. no need to impose ideologies on this evolutionary failure
This should be implemented worldwide
Brazil is right now facing yet another crisis of diseases transmitted by Aedes Egypti. It has already become epidemic. And with the global warming and record number of floods, those mosquitoes are just thriving.
To me, this is a moral issue. Millions of fellow human beings are killed or crippled by catching malaria. We should always prioritize human lives over all other forms of life. It would be very difficult for someone to go to the places ravished by malaria and say that their lives are less important than their killers. (Or those who carry their killers)
Given that, I do agree that we should research the consequences of a mosquito gene drive. Getting rid of malaria wouldn't be very useful if it causes an environmental collapse that would hurt those who we are trying to help.
This "dilemma" has been going on for years. I have no faith that we will ever do this
People are already doing that for years though
I hope not.
The most important thing is that we're having conversations about who should be having conversations about it.
You should learn CRISPER gene editing and do it yourself, there’s no laws on it.
look at singapore, we have this and it’s mosquito free in the city area
I had to deal with the pain for years on my right ear when a mosquito went inside. So unforgivable.
It's tempting to say "I only have this choice because I'm not affected. I don't personally know people who have died from these illnesses. Anyone who did would pull the trigger immediately." But only asking people who have seen those deaths would be appealing to emotion, and emotion is not how to make good long term choices. Could there be "butterfly effect" results? Could something worse fill the void left by mosquitos? I'd say the likelihood is small and that the benefits of eradication are worth it, since the current rate of suffering is so high. But I'm no kind of an expert and would hope that this kind of decision is made by people with more knowledge than I. Indeed, it shouldn't be subject to a democratic vote, but I'm also not sure I'd trust either a random mad scientist or politician.
In the last 10 years mosquitoes in Greece have gotten thrice as large and survive all year round, even if it has 2 weeks of cold and snow outside and neither the stringers insecticides nor repels affect them in the slightest anymore. If you make their population crash this much I'm afraid what kind of semi indestructible monstrosity will emerge from the remaining 1%
0:20 that animation was trippy
i did my biology project in this subject 2 years ago and i got the conclusion whe should totally try gene drive to kill harmful mosquitoes. i got a seven. One of my teachers wanted to give a ten and congratulated and even offered to write me a recomendation letter when i decided to enter university. The other one, a older ladie with 3 degrees, gave a 6 and told me my work was really good and it showed how much effort and care i put into it, and that she would never reprove a student for such work, but she also said that my conclusion is wrong and that "sometimes mankind focus more in how to make arms than in how to use them properly". i have to say, the last teachers is one of my favourite teachers of all time
with 3 degrees she doesnpt know that only 7-8 disease causing mosquitoes are there out of 1000's of species...and all 7-8 species are invasive species, introduced globally by human activity...removing invasive species is healing nature
In Australia, we have had some bad incidents with biological control, the most infamous being the introduction of the cane toad as biological control. I’m glad the consequences are being evaluated.
Absolutely yes. Don't overthink it. This is a good plan.
Yes , just yes . No dilemma here.
mosquitoes ≠ moral dilemma. slap them, it’s justice
The question shouldn't be "Should we"
It should be *"How can we"*
The question absolutely is "should we?" Ecosystems are insanely complex. Mosquitoes play very important roles both in aquatic and terrestrial ecosystems, erasing them could have have disastrous consequences. Making mosquitoes immune to mosquito-borne diseases without affecting their populations is a far more promising approach.
@@seb0rn739 Yes, we should
@@seb0rn739
Immunity does not mean they can't transmit viruses.
Plus, they're already basically immune.
@@cymtastique They are not immune. They are themselves not affected by the viruses but that doesn't mean they are immune in an immunological sense. The viruses evade the misquitoes immune systems. When I say that we should make mosquitoes immune to these viruses, I mean that we should find a way to make their immune systems act against them.
That's a very complex question whether we wanna get rid or not? Mosquitoes are actually good for our ecosystems, but the think is we haven't learn how to control or make use of them in a right way or we are making them useless with our actions that which depends on humans whether to get rid or make careful assessment of the potential risk & benifits before destroying them completely.👍
I’ve been recommended this video exactly at the moment a mosquito bit me
Yes
Jesus loves you all and is coming back soon!
Believe in His death and resurrection and repent of your sins and be saved!
Remember that He died and rose up again for you to be in heaven with Him!
Have an amazing day ❤️❤

Does Jesus come to beings who believe in other Religions?
The mosquitoes aren't too deadly themselves
It's just the parasite
But they sure are frustating and irritating to live with
@@debangan almost 98% of mosquito species don't even mess with humans yet due to the actions of a few species, they all suffer the blame despite playing vital roles in different eco systems.
@@u-will-begin-2-cough-in-3-days You and I, we both know that when people say, "KILL ALL THE MOSQUITOS!", they're only refering to those 2% which do, in fact, mess with humans. For the common layman these are the mosquitos, thus nobody really advocates for eradicating every species a scientist might label as "mosquito".
@@lonestarr1490 I very much doubt that apart from you, me and many others like ourselves anyone else around the world annoyed by mosquitoes know this particular fact. Even I came to know this a few months ago. This wrong perception is especially due to the fact that humans are mostly surrounded by mosquitoes that DO harm them.
The parasite is too small an enemy to combat. The mosquito has the misfortune of being large enough to actually fight.
Love how almost the entire comment section has no dilemma
I have no empathy for mosquitoes themselves, I am a mosquito magnet, but I do empathize with the animals that eat them and need them to survive, mosquitoes are good as food because they are so abundant. Maybe we should just try to remove whatever poison or allergen that causes the itchiness and swelling
Isn't there a possibility that the malaria virus, if ecologically pressured by a collapse in its host's population, could find a new host that is potentially even a more dangerous transmitter of the disease?
i don‘t think evolutionary adaptation happens that quickly… if malaria could spread to other species as main hosts, it very likely would already be doing so. and besides, it would be hard to imagine a species more suit for spreading diseases across dozens of species than mosquitos.
Well malaria wouldn't evolve that quickly if its vector population crashes, as it won't be able to spread in the 1st place. Also it's a protozoa, not a virus.
does not work like that
As a few others have said, no it doesn't work like that. Still a good/reasonable question, though.
We first need an in-depth report of the consequences of the collapse of the population. Since everything is interconnected in a food web, removing something from it might just lead to a crash. On the other hand, scientists should research much more on a perfected cure to the disease, and the biggest ethical question should be answered with this: Should medical services-especially for diseases like malaria- be provided completely free of cost?
No we don't
the ecosystem isn't that delicate, if a species dies out, it often gets replaced by another species
@@elidoz7449 Hopefully we are the species that dies out.
Do u study this?
Species dies by itself. "Evolutivon!"
Species dies by Humans; "Unnatural Apocalipse! What about the consequences?"
When I was a kid in the LA area we never worried about mosquitos but those invasive Chinese mosquitoes are vicious and spreading fast
I love the idea, but unintended consequences could be terrifying.
"Life finds a way"
Life finds a way, just like it did for the dodo eh? We exterminate what could have been a potentially amazing domesticated food source but yet won't kill a literal living plague?
Here in Minnesota, we get bad outbreaks of mosquitoes(we have a lot of lakes and rain).
However, in the past few years, we have been getting less rain which led to less mosquitoes.
Mosquitoes lay there eggs in water, so with the changing climate might mean less mosquitos in certain areas.
ades ageypti mosquito eggs can survive without water also

as someone who's been serving as a mosquito buffet for most of his life - f yes. I've literally been making jokes about this for years oml
There gonna leave most mosquitos alone, just the ones that transmit desease. so your still going to get bitten.
This won't stop you from getting bit
"When i become priminister of the world first task on day 1 is killing all mosquitos" that kind of thing? I feel like that too
@@Ashkanman i mean sure but it would negate the risks of getting diseases like dengue, which i have personally suffered from - although mine wasn't the most serious case in the world
I live in India but I actually live in Kashmir which is a cold area so there are few mosquitoes in summer and no mosquitoes in winter and it's quite pleasant like this, I dread living in a place where mosquitoes are all year around since I'm not even used to them
It's weird to consider how casually we can consider genociding an entire species....
I'm in.
My question is that if mosquitoes were completely eradicated, is there something WORSE that could replace them like, I dunno, other bugs replacing the role of what mosquitoes do but it's doing ten times more harm to humans as a whole?
Not quickly. Evolution is slow. And if we see something else starting to be a problem, we can zap it with another gene drive.
The ethical dilemma arises from how much we _don't_ yet know about the sciences...would this gene drive give birth to another kind of sickness which could spread to humans? Hard to say at this stage.
I feel that no matter how many studies are carried out about the side effects, we'll never truly know whether it's worth it or not.
Best to lay all other options on the table...open and creative thinking is needed.
Personally my idea is to see how the environment can be changed to discourage mosquitoes to populate poor and clustered communities. Whether it be through natural insecticide plants or particular natural scents or urban design. Something a little less intrusive....
So much to learn!
How would this would impact ecological notions if these organisms were to be removed from the economy's that they inhabit?
What would the consequences be and would it be benefital to remove them at all - opening a possibile niche for some other organism to fill instead.
I'm not sure if that niche would be filled (if this scenario was implemented) or how quickly it would be filled by another organism.
This is just my rambling thought which I wanted to share. Please feel free to comment your pwn opinion underneath, I would love to hear :)
i was lost for a bit because of how captivating the animation was
As someone from Louisiana: Yes. Damn the consequences.
From Houston. We'll figure out the consequences later
The emotional detachment of this video could only come from someone who isn't directly effected by Malaria. Issues of ethicacy and the environment get thrown out the window when thousands are dying around you.
Perhaps. Can also be argued that an unbiased view could only be taken by someone who is _not_ directly affected by malaria
It's called being a "bio-ethicist". To justify their own existence, bio-ethicists must make ethics complicated enough to require bio-ethicists to understand. A simple "yes" that is the correct answer in this case is too easy. "More research needed on this difficult question" is what gets the funding.
Related stupidities by bio-ethicists. Stopping covid human challenge trials. All the people calling curing blindness a "cultural genocide of blind culture". Anyone saying "death gives meaning to life" or coming up with bizarre contrived ideas on how tech that reversed aging would lead to growing inequality and reduced social mobility, or whatever it is this week.
Absolutely yes and there's no reason in the world why it should be otherwise
What did the narrator say exactly say when she said, "For example what would you do if you found out that a criminal had poisoned a product yousel". I was not able to understand the ending of this sentence no matter how many times I replay it.
Me before and after watching the video : yes 👍
Woah this is good its actually like a research that's why i love ted ed❤️
I’m willing to take any risk or unforeseen consequences!
