Magpies (aussie bird) has started to learn how to hunt the cane toads, more and more they are seen killing the toad by pecking thru the skull then removing the poison glands before eating them
Adam Hilliard Good for the birds.
Adam Hillard, yes and no, the bird that you were thinking of are crows. Australian Geographic, Jan 18, has an article on it.
That is... Pretty intelligent to be honest...
Crows are super intelligent birds. They can even remember human faces for several years.
Kevin Benoit and it's even more impressive if you keep in mind that they lack a neocortex (like all birds), which does all the complicated higher brain functions like logik and such in mammals.
Some Australian Crows, aka Torresian Crows (Corvus orru), have figured out how to safely prey on Cane Toads. The birds rip the toads apart and eat only the non-toxic parts. This knowledge is spreading through the Crow population. You don't need to import more predators because the native ones are starting to take control.
Alyenbird - Ha! That's fantastic! I love crows, they're so fricken smart.
Alyenbird Fuckin YES CROWS
It'd only a matter of time before them crows figure out how to kill a human
I sometimes feel crows are the most underrated of all Avians..
Alyenbird They can do that! Sure, takes time, God given intellect to creatures also to survive + figure it out over a short period of time, it is human to screw it up, so the animals have to adjust, plant life, if humans would leave things where belong, animals can figure things put in a more civilized way, unlike humans are out to cause suffering, blood letting, killing for trophys, revenge, renown, or just like feeling superior over helpless animals or other humans.
"What happens when we're overrun by lizards?"
"No problem, we simply unleash wave after wave of Chinese needle snakes. That'll take care of the lizards."
"But aren't the snakes even worse?"
"Yes, but we're prepared for that. We've lined up a fabulous type of gorilla that thrives on snake meat."
"But then we're stuck with gorillas!"
"No, that's the beautiful part! When wintertime comes around the gorillas simple freeze to death!"
that scene pops into my head whenever i hear about stuff like this

Top Comment Hijack: Can we get a video about the bark beetle? It's destroying the rocky mountains.
Asian honeysuckle decimated the woods where I grew up. I had no idea what it was until I was an adult, so the last three years before I moved out I tirelessly pulled every bush and sapling of it I could find. I knew that eventually it would grow back from the surrounding area once I was gone, but by that third year I noticed more plant variety, and some new birds, toads and snakes in the woods. It was like a little haven for them I think.
FlintSparked Very well done ! Prayerfully it helped to continue the better ment of the forest.
make honeysuckle tea or just pop off the flowers whenever you see them, the flowers turn into more seeds and more plants
Two wrongs don't make a right, but three lefts do.

This reminds me of Yellowstone Park in the US. 100+ years ago someone decided that the wolves were killing too many deer, so to protect the deer population, the government let people hunt and kill the wolves. To extinction, of course, because the government is great at screwing things up. Then there were so many deer, that the local plant live was decimated. And with the plant life decimated, a great deal of erosion occurred, and a great many of the native species of animals were threatened. All because someone -- with the best of intentions, mind you -- decided that the deer needed us to intervene and protect them. Finally, after damn near a century of destruction, wolves were reintroduced and the park is finally getting back to normal.
Lesson? Leave things the hell alone!
That is always the case when the government is the one doing the importing of non domestic animals.
LMacNeill Very well worded + to the point!
However instead of reintroduceing the wolves the could have just let people hunt the deer more venison for humans and no wolves moving into the ranch lands
Didn't they introduce the wrong species of wolves though?
@@frankorner8797 but hunter want to get paid so yeah I don't think the government want to pay them a load of money to hunt deers
Invasive plants can also be ecological and economic disasters. They are frequently purposefully introduced to an area for agricultural or ornamental uses and subsequently naturalize and negatively impact the environment. They can be extremely difficult to eradicate.
LOVE OF PLANTS 🌻 Omg the Kudzu invasion of the southern U.S. is crazy!!
In Washington state where I live, scotch broom is a horribly invasive and aggressive plant. It's ugly, chokes out native plants, hard to get rid of and poisonous to livestock.
LOVE OF PLANTS 🌻
Yeah, just look at kudzu and pythons wreaking havoc in the southeastern U.S.
My (very large) backyard is plagued with lead trees, thousands of seeds, regrows from stumps and the roots send up new shoots. Must go kill some again tomorrow.
Potato Durp This made me laugh because my landlord is trying to eradicate a giant patch of the stuff...and has it in their head that throwing carpet over it all is gonna help.
You can imagine how well that's worked.
You should have mentioned about invasive plant species as well. Kudzu is a HUGE problem in the southern United States.
Personally, my most hated introduction was the idiot who decided he wanted every bird mentioned by Shakespear to be living in central park. Now we have Starlings out competing blue birds for food and English sparrows out competing purple finches for both food and nesting sites.
Technically humanity is a invasive species we have no predators and we don’t serve the planet at all.
Xiaomu K that’s were your wrong ether a specific species works to benefit another one like a symbiotic relationship, pollinating flowers our controlling the population of another species. Face it humans are garbage and have no actual value to the planet as a whole if you get offended by that than o well.
robert rainford what Xiaomu K means is that everything is just doing what it does to survive. Yes they are benefiting to their ecosystem but they don’t know that.
Chris Fielding you are right they don’t know that and they pretty much are doing what they need to for survival but they are doing it the way nature intended we’re there are serving a second function besides that. Human being don’t serve any purpose to the earth anymore and fit the category of a invasive species.
@@rob20ist Don't worry about it. Humans barely survived the twentieth century.
Trying to eradicate a species from a small island is different from trying to eradicate it from a continent .
thats quitter talk
Let's bring in something else, what could possibly go wrong?
@Naki Ryan only if you aim high😀
Populations grow exponentially, the larger the land mass the harder it will be to eradicate a species, exponentially. Also this island was not inhabited by humans, they didn't need to hunt in anyone's backyard or under the deck or in the attic
@@sleepy_boi7552 for example if you create a disease specially for a rabbit like In the video other predator will adapt to hunt another species and will hurt the ecosystem.
What special kind of idiot would introduce a poisonous, toxin shooting frog (that can blind you) to control beetles when you could use yee.... ANY OTHER ANIMAL. This one doesn’t even make sense.
That1Valentian they are those beetles originally, catching them wasn't a problem since they are ginormous, carrying them was easy because they eat anything and... Sugar cane, cane frog, makes sense
Shockwave Shockwave your comment doesn’t make sense. Can you please edit it?
Shockwave Shockwave You do realise that the “cane toad” was only called that after it was used in Australia. Another more common and older name is the marine toad. Honestly, if you’re going to inform someone, do your research.
Boglenight
What was he saying?
That1Valentian I could only work out half of it, but that half had me face palming so hard I almost broke through my skull.
Aren’t we technically an invasive specie? We traveled to tons of places we weren’t supposed to and destroyed a lot of the ecosystem where we go.
No
Yes, we as humans are, humans started in Australia, and spread all around the world, and then we slowly break down the ecosystem, and we have the power to blow the earth to hell, so all of those makes us the real symbol of invasive speicies.
We are far worse then any of the other creatures.
@@zakscrazyworld1239 Humans (or at least Homo Sapiens) started in Africa
No, unlike cats and rabbits we are not blinded by our instincts to hunt or eat everything until there is nothing left, we have an ability to see the bigger picture that they do not have. Think of feral cats as you would the Borg from Star Trek, they are driven by the need to kill and multiply, and they will do just that even if it means killing off everything and then starving to death, they cannot reason and cannot be reasoned with and must be controlled aggressively.
He didn't even mention the funniest part; the cane toad was brought in to kill sugar beetles, but the beetles actually tended to live a foot or more up on the sugarcane plants, and the toads just couldn't reach them at all. So they spread out and started eating everything except what they were introduced to eat. They were able to eat some of the larvae (grubs) of the beetle which dwelled in the soil, but nowhere near enough to actually help.
Some crows in Australia have actually learnt to eat cane roads by flipping them and avoiding the poison glands, they have also been seen learning this from each other
Sometimes you just gotta get the infinity gaunlet
Aren't rabbits Australia's poster child of invasive species?
Matthys Fourie...rabbits, cane toads and emus. Australia has had a lot of invasive species issues.
Emu's are native to Australia. We have massive problems with non-native species; pigs, deer, water buffalo, camels, donkeys, horses, cats, several species of birds not to mention dozens of plant species, and its anyone's guess as to how many species of fungi and soil dwelling organisms are out there and what kind of damage they're doing.
Drop Bear...my apologies. I heard about the emu war and assumed they were yet another Australian Invasive case study.
No, that was a case of "ignorant governments caving into pressure from farmers". Emus are native and very successful. Farmers don't like giant birds strolling around their land.
It's same reason stuff like the Tasmanian Tiger is extinct. Farmers thought they were a threat to their sheep...so had them all shot.
@@blackstar19gammaburst85 There is always one.
That's how we got the stupid Lionfish in the Atlantic some clown threw their pet Lionfish into the ocean and boom we have our current problem
Sharky says her friends the reef sharkies are training to eat them...
Kudzu in the southern U.S. Burmese Pythons in the Florida Everglades. The Brown Tree Snake on Guam.
Is that the one that was eating all the birds?
Yes. BTW, the last I heard, the government is trying to kill all the brown tree snakes with Tylenol.
Don’t forget lionfish in Florida
Meanwhile Pythons are taking over Florida.
Quaglium Quagnarr , can pythons swim? 'Cos Florida's gonna disappear below the waves...
Massimo O'Kissed - The sinkholes will swallow up Florida.
Massimo O'Kissed Yes they can. Almost all snakes can swim.
Massimo O'Kissed Long before it sinks because of climate change it’ll sink under the combined weight of all the non-natives. It’s not just pythons, it about a hundred different animals like the iguana, cayman, fire ants, boas, and the list goes one forever. It’s rare to see a native critter in FL and the further south you are the more difficult it becomes. We have 4 species of crocs/gators and cayman living in the everglades. That’s two too many.
Teach a Python to drink Java and you will see plus-plus results.
The most invasive species are memes , they have literally filled up all of my phone's memory jungle
No your phone's memory is the invasive species.
Long live memes.
This is true...I've sacrificed many an app in the name of memes.

Excellent video! Thank you for raising awareness on this vital issue.
I live on Guam, which is out of control with invasive species. The local people like keeping dogs as pets but they almost never have a fence nor stop their breeding capabilities. So, if one neighbor has 4 dogs and another neighbor has 4 dogs, too, then those dogs will easily turn into 40 dogs within the year. The island is about 35 miles by 16 (I think) and there are a couple thousand dogs per square mile. To add to this dog problem, some people who can’t fly out on a plane with their pets just release them. The Guam government passed a stupid law a while back saying that if you get a dog fixed, then you have to keep it. Guam is so screwed up rn and the government won’t allow anyone to shoot the dogs in case they have an owner. Btw, the wild dogs suffer, too. They all have really bad mange, starve, and are ridden with disease/parasites. Rant over; have a nice day
ToothlessTamer Industries Elite govs all are idiots. Care not about citizens or animals, just stupid laws. Spay, neuter best thing for cats + dog population control. Humane Societies are no good, only independant refuges + santuaries reall help. Need a group backed by animal loving rich person could help much.
Wow, that neutering law is the dumbest, most damaging animal law I've ever heard of...
What does the Guam government get from passing that law, huh? Very confusing.
Welp, people are gonna have to either neuter the males secretly (not females because they need hospitalisation and care over days; meaning you can't hide the fact that you neutered it), or start hiring doggy hitmen to cull the dogs in secret.
I live in Miami, one of the biggest hub of introduced and/or invasive species. Arguably some do more damage than others but there are probably a hundred different animals that call my city home. I’ll just share the ones I know about. Geckos, anoles, curly tailed lizards, monitors, iguanas, cayman, nile crocs, pigeons, some species of finch, mallards, muscovy, a few species of turtle including the side neck, fire ants, cats, dogs, boas, pythons, swans, egyptian geese, grey geese, chickens, peacocks, cane toads, not to mention lots of invasive flora as well. Some of these are escapes (especially after hurricanes) from the local animal parks including the zoo, animal breeding facilities and people abandoning animals everywhere. All of these I have seen with my own eyes except the croc and cayman but there was extensive reporting about them and honestly I’m too chicken to go into the Everglades. Every day I see less native wildlife near where I live and instead, every few months I see a new animal that wasn’t there before. The curly tailed lizard showed up about 3 yrs ago, the egyptian geese have been around here for just over a year, 8 months ago the biggest damn geese you’ve ever seen in your life made their home behind my apartment building and about 5 months ago chinese chickens (hens and roosters) started to call my neighborhood home. SMH. What can you do with a place so overrun with non-natives? It seems too late to save Florida’s native populations.
MissLilyputt There's a marine animal as well, I think it's called a "lion fish"? Someone help me out here, what's that thing called?
lionfish.
Any ecosystem: exists
Humans: Allow us to introduce ourselves
Cane toads (or Sapo Cururu here in Brazil) doesn't spray venom. He only releases venom if attacked (for example something biting on it or grabing it) because it needs the attacker to squease it so the venom leaves the venom glands
Wow. So well researched and presented.
I remember seeing mongooses in Jamaica. That's when I first found out about how wide spread they are. Great piece.
"Life, uh, finds a way..."
-Dr. Ian Malcolm
3:34 similar stuff happened in Galapagos island where goats started multiplying and started to stamp on baby tortoises though it was involuntarily it caused lots of issue in it's population and so they eradicated every freaking goat there is.
But one creature which was native to Australia ppl couldn't eradicate, and they're known as emu
Well put - Thanks!
for the cane toad problem, just declare war on em and hope you win this time
I think I remember seeing in another video tday (TierZoo's Australia video, specifically) that some birds have actually started learning how to hunt cane toads, by attacking them in areas beside where the poison glands are. Another cause for hope there, and evidence that while affecting the environment should be minimized as much as possible, nature is a lot more resilient than some environmentalists give it credit for. Reminds me something I saw that said that great white sharks actually DO have one natural predator now, Orcas which was rtemarkable because the way they hunted sharks was incredibly tactical (involving stunning them first) AND because it revealed that as they decompose they release a chemical that tells all others of the danger, causing a reaction so great it can even override their inverted 'trance'. It's being researched for use as a shark repellant.
Mass killing Cane Toads is also a pain.
I have a pond in my backyard. No animals live in it.
Last Summer, I found A LOT of Cane Toad Tadpoles in there.
Thousands of black bulbs, casually swimming around until they can get legs and hop away.
As a pet owner who's had two dogs die in the past from eating toads, my immediate reaction was to kill them all.
I got bleach, a tarp, and some pegs.
Poured bleach in, laid a tarp over so no other animals got affected, filled it in with dirt a week later.
Come Autumn it was the biggest mistake ever.
Without any natural predators around, the Spider population boomed.
I was constantly walking into webs.
Very good video. Congrats.
This may be an unpopular opinion but very carefully done I feel that invasive species are a case where genetically engineered viruses might be useful. We may not be able to quite do it yet but we are close to being able to modify and or engineer viruses to target specific populations with specific effects. Might sound scary and with the potential for great harm but it’s actually probably less dangerous than introducing yet another species to eradicate one.
Locut0s they are trying to do so with rabbits in Australia.
as long as it doesn't end up being an invasive virus ;)
In addition to that, they could already have the cure ready in case the virus spreads to the native area of the species..
How would you make absolutely sure the virus would not jump hosts though?
The whole "shoot ever cat on sight" & "in less than a decade the rabbit population grew again" is so freakin hilarious
Excellent video! Just want to add a little more important but often overlooked information.
Invasive species aren't exclusively animal species; they can be plants and fungi too. Some good examples include prickly pear in southern Australia and the Chytrid fungus which causes disease in many (but not all) species of frogs and is currently wrecking an awful lot of havoc bevause of a disease it carries. It's spores are also very easily spread, and humans travelling all over the world help it to get to different places. The frog population in Panama makes an excellent case study on that one).
Another thing to note is that often our domestic pets and livestock are non-native (this depends on where you are in the world) and can do an awful lot of damage to the local wildlife. Feral cats (and domestic cats left to roam, too) in Australia kill very high levels of native fauna every day. Cattle, horses, camel, sheep, goats, pigs and deer are also non-native to Australia and the clearing of land for them to roam is equally problematic as it removes vital habitat, and their hooves can ruin the delicate ecosystem and brumbies (wild horses in Australia) spread weeds.
To make things more complicated; animals and plants can be endemic to a particular country but can cause problems if put into another region in the country to which they are not indigenous. A good example is sweet pittosporum, a type of tree that was spread around Australia as a plant for gardens. This particular tree does well in certain habitats but when in woodlands it dominates and takes over, taking most of the water and shading the smaller plants on the ground that otherwise would get more sun. It should be noted, though, that this isn't always the case. For example, a species of fish in the galaxiidae family in Australia was threatened by invasive species of fish such as trout that were eating it, so a group of ecologists moved the species from he mainland to a lake on the island of Tasmania where it is normally not found so it's population can increase with relatively no consequence on the local wildlife. We can move animals around but it requires a lot of caution.
Invasive species cause a lot of headaches for conservationists and it's rarely an easy task to manage them, not to mention doing so ethically. A lot of the time invasive species are demonised too, which isn't exactly fair because it's yours truly - humankind - who caused the problem in the first place. The animal, plant or fungus doesn't know it's disrupting the ecosystem, each organism is just doing what it evolved to do. At the end of the day it was some naive humans mistake that an awful lot of organisms have to suffer for.
In Brazil the european wild boar was introduced in southern farm areas to serve as game for rich landowners and cattle keepers. It ended up breeding with domestic pigs and now huge packs of crop-destroying, livestock-killing half-boars swarm these areas.
So was it the cane toad that Homer licked on that one episode?
Edit: the part about unwanted pets being dumped is really sad. Today my friend, my mom and I rescued 2 kittens from the dumpster. They didn't even opened their eyes yet. Who does that?
So, I shouldn't base my concept of conservationism on the children's story about the old lady who swallowed a fly? Hmmmm... I dunno. Seems like a good idea to me. 🤔
As a kid in Miami we’d get pet snakes from the fair. When they got too big for the aquarium we would let them loose outside. Now it is natural to find boa constrictors everywhere in the wild.
Reminds me of what was done with the feral hogs on the Channel Islands. The Island Grey Fox would not eat the hogs because they had never seen them before and thus the hogs ran rampant and eventually the National Park Service hired hunters to come on and shoot every hog. Also if because of fire control a species of tree that normally lives in mountain and hill crags and is highly flammable moves down into valley below because the risk of burning is significantly lower is that species invasive. They do harm the local environment because any fire now has much more timber to burn and thus is much worse than historical fires. For the life of me though I can't remember the name of that tree.
"cane toad" that's an odd name, i'd have called them chazzwazzers

My dad's favourote tidbit of info about my mum is that her grandfather helped introduce cane toads to Australia. He enjoyed telling people that whenever he got the chance, just to gently annoy my mother.
I have been told house geckos are invasive especies in Central America but they actually help with insects, always wanted to know if it's true
GECKO M hardly control insect population, and are themselves a nuisance
but house gecko do convert household insect into poop droplet, it is an annoyance to have poops in furniture and dishes but if your house is sealed then they'll rid your house of flying insect eventually.
My mom told me to never get near one they’re dangerous.
xponen_ flying insects usually leave house or die within a day, but lizards jumping around here and there is irritating
not at all dangerous.
Dogs, Man's best friend, ALWAYS ♥
and apparently rabbits' worst nightmare.
borRIING cAN CONFIRM, I have a chihuahua who's favorite thing to do is to go into rabbit holes and drag out rabbit pup carcasses every spring.
Cats: tiny tigers who live in your house.
Except for when dogs become feral too because they were abandoned, or just because some country people just let them roam around so they save the walk time. And then some go killing around and they blame wolves. That happens where i live.
True, but did you know that dogs are lasted as one of the world's most invasive species? They have been ranked in third place as the most damaging with cats in second and eats in first.
In the southern US, we have problems with two species of fire ants introduced in the early twentieth century, The nutria, a large rat-like rodent, became a nuisance almost immediately upon introduction. Africanized honeybees are a life hazard in some regions, The walking catfish, the snakehead fish, the boa constrictor, hundreds of species that seemed innocuous at the time have become environmental disasters, and I have only mentioned the animals.

For some reason, this has got me thinking up an idea for a movie plot.
Imagine hundreds of millions of years ago, alien lifeforms introduced humans to the planet Earth. Fast travel to modern day, and now they’re basically destroying the entire planet. So the aliens hatch up an eradication plan just like how we did with the Macquarie Islands, except it’s basically aliens hunting down humans because humans are terribly destructive. The twist is that the aliens hold no animosity towards the humans whatsoever; it’s just a conservation effort to them that their hunters are getting paid for from Galactic Federation funding.. or something.
You missed the most important story of invasive species control in Australia, i.e. the use of myxomatosis, followed by its vector, followed by RHDV and its vector. These pathogens are the core of the rabbit control program in Australia. I actually study the potential of using viruses to help manage the most invasive fish species in the world, common carp. Unfortunately, the failures of ill-planned one-off approaches have led to a very negative light being cast on scientists attempting to develop innovative strategies for control of invasive species. Biological methods like the propagation of disease (similar to the meat ant strategy you explained) is a method that carries a lot of criticism but that I am hopeful for. Using species or even pathogen already present in the system can be called "conservation/augmentative" biological control.
Maybe I'm an idiot for suggesting using gene drives to fight or eliminate invasive fast breeding animals.
unknown bc
well it got rid of the toads...
...but now we have a zombie problem...
unknown bc - I live in Australia and have lived in toad infested areas for a good part of my life. Over the years there have been a number of programs to try and control toad populations, some more successful than others. Currently there is a program (not sure what progress has been made) to control the toads through genetics. A Google search will provide results.
I literally have/had(?) an eldery cousin (like he was my grandmothers cousin..not sure what you call that) I once visited who was literally working for our national scientific group on this very thing. So it's been looked into but it's not a quick fix.
When you realize the humans are the invasive species
Wild rabbits, cats, cane toads and carp are huge problems in Aus. There are also heaps of invasive plant species like olive trees and blueberry bushes that are wreaking all kinds of havoc on the land. Hopefully we are able to do something to fix this issue before it gets any worse
5:08 thanks for the warning. I was about to facepalm really hard xD
Scishow is invasive of my time LOL. But it is worth watching.
What if the meat ants become invasive species in the areas they are encouraged to make colonies?
DysnomiaFilms they're native. They just haven't made a colony in that feild yet.
Ammy Marsh Native to the country but even within the same state you need to be careful about introducing species to an area they weren't before
Gotta admire species that persist despite human habitat destruction
That one about the island is an invasive species nightmare.
Apparently these explorers and colonists have never heard the nursery rhyme "there was an old lady who swallowed a fly" smh...
Humans talking about invasive species...
Get outta here ya depressive misanthrope
C L you probably think we were brought here from mars by reptoid aliens
C L says the human
Ig you have a point
Clearly this "thing" is one of the underground lizard people that were native to America. However when humans came in (I'm talking about Native Americans not the other invaders.) Mark Zucc is another lizard person who is secretly using facebook to brainwash humans into a state where they are unable to put down their phones so the lizard people can drive humans out of America and take back their home. And you can trust me on this, I have now done almost 10 years of research, studying these creatures and I warn you Americans to be ready for their violent revolution.

Humans are the most invasive of all
This comment but 100%
My favorite pets, house cats, are an invasive species here in North America. Bird lovers are always agitating to get them banned. Say what you want, though; I’m not giving up my pets.
(Mine do stay indoors, though.)
Gary Cooper It really sucks that cats have become an invasive species. If they were just indoor cats everything would be cool...I used to have a cat in my neighborhood that would hunt native birds, mice, voles, and rabbits, and then come sit next to me on the porch...
Nobody Knows Not at 400 years. It still takes at least a couple of thousand for a mammal like a cat to truly become part of an ecosystem. Since they aren't controlled well by other species and wipe out the majority of native species, plus they are non native, they are classified as an invasive species. Just letting you know I'm not saying I don't like cats, I just wish that they weren't so much of an issue.
Wojr B predators usually dont need to be controlled. Their population only grows with their prey. But when it is not its original place it does not always find the balance. For example foxes and cats in Australia.
yes, and added to that a domestic animal lika a cat will NEVER find any semblance of balance since people protect them - after all, pet owners typically don't agree to their pets dying because of natural selection, haha.
A birder myself, I agree that outdoor cats should have NEVER been a thing (except on farms, where mice are in abundance) and I think they should be banned in favor of people taking their cats for walks on leashes. This is taboo for some reason, but it's inhumane to trap a cat indoor their whole life. Look into cat leashes!
If you live in Southeastern Pennsylvania there’s a good chance you’re familiar with the Spotted Lanternfly. Native to places like Cambodia & Thailand, five years ago the species began appearing in Berks County and this summer has spread as far as Philadelphia and Harrisburg. They can everywhere at times.
No not really I've never heard of them
This excatly what happened recently in Sidoarjo, Indonesia. Someone has released the Arapaima fish, which is, invasive species to nearby river and it cause problem with the ecosystem. It's pain in the ass to have such an invasive species that could destroy the ecosystem.
or maybe.. we are the invasive species.
the number 1 invasive species: human.
Well, unless you want to start eradicating humans there’s not much you can do.
Nuclear winter?
dippst
We are all different. Which causes many problems but is also a good in many ways.
We fear those who are different because we are afraid of the unknown. We hate those who are different because we are afraid and we believe they may hurt us. We want to destroy what we fear because we dont know them and we are afraid of them.
Ignorance (lacking knowledge of a particular subject) causes Fear.
Fear causes Hate.
Hate causes War.
War causes more hate and fear...
I agree, you ARE super annoying.
Jerms Mason, we aren't, we just have a Marxist roach problem in the U.S. right now. They pop up once in a while and make genocide noises, don't worry, they'll go away soon.
Best host on scishow!
The story about Macquarie island had me falling off my chair. It just kept getting worse... I'm glad they solved the issue.
Aren't we the no.1 invasive species
DOOMZDAY no we migrate in a weird way
609tw1ss anims I guess we're still the wierd guys in the planet
Start with People
You first.
3dgy
We just kinda migrated everywhere during the last ice age, so we're not technically "invasive"
Yes! I agree!
only people in Africa and Middle East should be left. wow, we were supposed to be in those places now look at it, it's just not a happy place.. we were an invasive species to America and now look at it!
5:08 perfect speech to make someone face palm too hard when playing a video game
I was shocked to encounter a large praying mantis in Canada in an area with relatively harsh winters. Turns out there are native tiny ones but this big guy was a tropical import brought in to control bugs. But of course they spread out rather than just staying put in the fields... and this one is even outside where they said they had spread to.. But as far as I know they're still rare. I'm just amazed they can survive in a climate so different from home
Arent we invasive species?
I dont think so. During the time we "invaded" the planet, we were pretty much just migrating naturally as far as I know. Besides it was several thousand years ago, and long enough for us to adapt biologically to our new envirorment and become part of it. We still damage the envirorment a lot though, but then again we are also the only animal that can actually deliberatedly limit the damage to the envirorment, limit our own reproduction and even have a great potential to fix the damage already caused (like eg cleaning up the trash from the ocean).
zakosist i mean. We're more suscessful at wrecking the ecosystem then any what we call invasive specie.
You may be right about that. But that doesnt mean we shouldnt try to get rid of other invasive species, they still do damage. And humans have a very great potential for improving in many ways and can understand that. We keep trying to make new solutions and inventions, that at a certain point might actually reverse the damage
zakosist Then based on what moral high ground can we judge which speices deserve eradication, when the same moral principle cannot apply to ourselves(or more like unwilling ), we should atleast put more effort in neutralizing the threat instead of going for straight up genocide.
As I see it, there are more problems with killing humans than most other animals, mainly because we have a much higher intelligence, thus higher awareness. It does matter that we are capable of complex thoughts about the future, life and death etc. Most animals can feel fear and have instincts to survive, but its still at a more primitive level (maybe except a very few species like chimpanzees). I think animals should have a minimum of protection from both extinction and suffering we may inflict on them, but not at the same level as humans. And you cant ignore we have political power and personal rights. It would be a big political problem to decide who do and dont deserve those rights, which could become motif for riots or wars. Plus the only way to neutralize the threat in most cases with invasive species is actually to get rid of them. You cannot tell them to change their ways. With humans there are lots of alternative solutions to live more envirorment friendly, and even more that we have potential to develope. What if we ended up killing the person that could actually solve a major envirorment problem?
Because whenever they’re actually dieing humans that don’t know what their talking about are like... OMG WHY ARE YOU KILLING THESE TOTALLY INNOCENT ANIMALS THAT BELONG HERE?
How are they not innocent?
More videos about invasive species eradication efforts please
Background music, that's what this show needs
in one place in england they had a huge rabbit problem so what they did was they started capturing rabbits, sterilizing them, and releasing them, and they would compete with fertile members to reproduce, thus preventing a whole new litter of rabbits being born, for however many mating cycles they lived for, and it actually worked well.
Moose are an invasive species in the area around my hometown, the difference they have from those on this list is that they have successfully integrated into the ecosystem with the brown bears happily hunting them.
Some of the most common plants and insects here in Maryland are invasive. Garlic mustard, wineberries, trees-of-heaven, ground ivy, common ivy, oriental bittersweet, and lesser celandine are just a few plants that come to mind. Obviously the most annoying invasive insect here is the Asian tiger mosquito. But there definitely are a lot more species of invasive insects that are detrimental to crops in Maryland.
the cane toad, in trinidad we call them 'crappo' the local vernacular for crappaud, which i think is french for toad.
GREAT IN FORMATIONS ..... THANKS FOR THAT ....!
I always wondered why we can't spay some stray and then send the toms out to take out the Rabbits, Bureaucratic notwithstanding.
yes and no cat can live a good 20 year if they are lucky
I have the cane toads on my property here in Australia, so I can tell that you have exaggerated a bit, they are actually slow, stupid and don't spray poison, just don't try licking their backs unless you want to get high, which some dogs actually do. We personally don't kill them because they kill the snakes that would otherwise be a threat to us (and we are not allowed to kill native snakes), so they are sort of like a troupe of poisonous kamikaze toads that form a defensive line between our home and everything else in Australia that would like to kill us. :-) Oh and the crows have learned to flip the toads over on their backs and slit open their guts to get at their livers without touching the poison glands on their backs. As or the cat, yeah now they are a huge problem, and in fact some of them are growing huge, so large that they will attack domestic cats and their owners. www.gympietimes.com.au/news/gympie-truckie-mauled-in-feral-cat-attack/3433735/#/0
i havent seen michael for years, clicked this video, and was surprised to see him hahaha
"Rikki Tikki Tavi" used to be one of my favorits movies and a lot of people dont know about it ❤
Just Australia? Cane toads, mosquito fish, water hyacinths, apple snails, carp, tilapia, etc. were introduced ON PURPOSE in pretty much all other Indo-Pacific islands as well. In the Philippines for example, those organisms are the MOST commonly encountered animal and plant life. Most of the native species have long been wiped out or pushed to near extinction.
This is why in Florida where we have those cane toads we often throw big rocks at them or we hit them with golf clubs
Yeah how nice! Just harm animals for merely existing.
Tasmania really hit that whole island scenario out of the park. Forward thinking if I’ve ever seen it lol
