Massive vines that blanket the southern United States, climbing high as they uproot trees and swallow buildings. A ravenous snake that is capable of devouring an alligator. Rabbit populations that eat themselves into starvation. These aren’t horror movie concepts - they’re real stories. But how could such situations exist in nature? Jennifer Klos gives the facts on invasive species.
Lesson by Jennifer Klos, animation by Globizco.
"Rabbits introduced to Australia because one man liked to hunt them"
well obviously he wasn't very fucking good at it...
he wasn't brilliant either 😒
noone can stop them. the cute fuckers breed so fast. once they get going you gotta make it legal for everyone to kill them on sight to cull them.
Hey you can't blame him. If I also lived in the 1800's and loved hunting rabbits I wouldn't think of the consequences either when I let 2 dozens of rabbits out in the wild.
your stupid
you're*(oh the irony)
Guess that one man wasn't a good hunter.
Or Rabbits really really can multiply
xD
It's because the rabbit outnumber him. 😂😂😂😂
@@UjwalRam rabbits multiply pretty quick
Yep
That tiger is finding that snake skin really tough to bite through.
That's actually realistic. Snakes are just pure muscle with bones and hard scales. Even tigers have trouble eating them.
@@Bullboy_Adventures snake dont have bone
@@khaipinaulak485 snake do have bones

First of all, the animation and art in this episode is absolutely beautiful.
Second of all, I never expected to hear the line "in Australia, the lack of predators..."
Poisonous animals, despite obviously dangerous, aren't necessarily predators.
😭 deadass, all those scary animals, and none of them could reduce the rabbit population
@@jorgeantoniocab49 Australia popularly has more venomous animals then poisonous. Perenties for example.
@@jorgeantoniocab49 Aren't dingos also predators that hunt rabbits?
@@olegsurchi7411 I think it refers to having different reproductive cycles. Dingos might eat some, but rabbits will always outnumber them.
Yup, we're definitely invasive. Except we are different in the way we actively change our environments to suit our needs which allows us to be literately be almost everywhere. We disrupt ecosystems much more affectively than any other species.
Like beavers and other successful species, we modify the environment to allow ourselves to thrive.
@@KaidaCresto stop the pretentiously self hate , there's people making worth the time being alive , also considering that then what is a healthy ecosystem ? A way to kill off the excess amount so it doesn't get out of balance , how bout a higher race killing humanity so it doesn't thrive , you live by eating and some point you die , end of story
@@julian.a9542 i can like barely understand the surface of what you just said. So going based upon the idea you just presented, the earth is already overpopulated anyway. If anything, those higher beings would be needed at some point in the future if the population of humanity continues to grow as it is now. Otherwise, we would be lacking in food sources and die off anyway.
Definition of invasive speccies
Have no predators humans:- yes
Have large population:- definitely yes
Disrupt ecosystems:- ofcourse yes
We invade, and we accidentally bring things that like to invade

On a Ed puzzle
This was a beautiful animation
A fun storie from my country, Hungary:
Acacia was brought in in masses to stop soil erosion and it ended up swarming everywhere. Now it went back to a kind of normal state and it became a huge benefit for honey production.
I did a paper on invasive species in my undergrad. I went in all gunho about to write an essay on how bad it is and what we should do to get rid of them. All the research I did (from peer reviewed articles) made me end up realizing that once a species is established as invasive, it's impossible to get rid of them. The best we can do is mitigate the damage they do until they naturalize. In a few thousand years, they'll turn into a new species from their parent one. That's how nature works and made me LOVE it more.
In a thousand years only species left will be insects, fishes, humans and the animals we eat.
Dang, what a plot twist at the end.
Plot twist,?
When I read the title I thought he would start with Human...
He just took some time to get to it.
Nothing and no one can be as invasive as human beings.
May be we landed from another planet to destroy planet earth.
So, its a fight between us.
Our children will wait and see, whether they will be destroyed or earth 👽👽 🌍
Do you know what a plot twist is?
Haha haha why is this funny for me
we're being invasive by making organisms invade other ecosystems
i saw the ending coming from miles away, when you started to talk about : destroying ecosystems. Well , we are an invasive species, no doubt
Guys blame evolution and monkeys
Even if we are an invasive species who cares? If some species can’t adapt its their problem not ours.
@@AnterresGaming Did you even watch the video? 🙄
Robert MacKinnon yeah of course I ll instantly die. There is no such thing as other spices to fill in their ecological role
@@AnterresGaming no, there isnt, species dont just appear out of nowhere, they evolve in a long and tedious process. Humans do way to many things way to fast in order for ecosystems to adapt accordingly or for other species to take their place, (which only makes sense in predator prey situations, when one gets kicked out, but even then they dont take the place of the other)
I really like the artwork of this video
Here in Brazil, some species of plants seem to be native, but they are not.
The ballast sand from Portuguese wooden ships was removed in tame bays, for hull repairs or replacement with payload. Along with this sand, seeds of plants usually came from India, China, Maluku Islands, etc. For most Brazilians, they are native plants.
Who else is here because of online schooling during coronavirus?

@Cat Queen 999: Rabbits are notoriously good at reproduction. They need their predators. They are propably what Star Trek Tribbles are based on:

We are the invasive species
@Vince FTW: It appears we are self-regulating to restore some level of balance. That old theory of the "Population Explosion" belongs into the realm of legends now:

Dingos, Venomous Snakes
+Crono
Yeah,your right but dongos I agree,but venomous snakes are not natural predator of those new rabbits
+Crono Dingoes are virtually extinct. They also are not fast enough to catch Rabbits who are extremely fast when they want to be.
Ted : "are we an invasive species ?"
that's.. pretty deep bruh
It's true tho
Invasive species in a nutshell:
Species from other parts of the world that were somehow introduced to a new part they aren't native to, with no natural predators, they breed and take over the area due to the lack of predators.
We are an invesive species. We are nature. We do the same as those rabbits, using up all the resources until many people will die and then do it again and again.
"I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species and I realized that you're not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet. You're a plague and we are the cure." -- Agent Smith
+masterimbecile Oh my god! The men in black are on to us!
Yeah, I've come and gone in this roller coaster of moral and ethics about how bad it is to be a human, about how much we hurt the environment, and the idea that we should feel bad about it... But the truth is, we are either the result of natural evolution, or the design of a great actuator. No matter what you believe, both scenarios mean that we are not in control of our development as a specie, all we can do, is to be aware of the situations that arise around us as a result of our interaction with the ecosystem, and if we truly want to get a hold of the reins to our evolutionary process, we need to stop making us feel bad about ourselves, and accept who we are and what we have done as humans.
Yes, the answer is yes
Lack of predators in australia...
+Nico Schnitman ...That will hunt and eat those rabbits. Most animals don't care to eat some species because they either dislike the taste, or haven't evolved to eat them. That's why most predators don't eat everything that can fit into their mouths. There are exceptions, though.
+Poison Flame rabbits are big they don't fit most of Australian predators mouths.
That's part of my point. Thanks for making it clearer for some. Rabbits can grow pretty big.
It's our fault, too. Predators like the marsupial lion, Tasmanian tiger, and the giant, carnivorous birds all are gone because of us, so nothing can find ways to solve the problem.
They still have dingoes, phytons, crocodiles and monitor lizards. Not to mention the most venomous spiders and snakes(if the rabbits managed to piss them off).

Hmmm, guess I commented too late.
+TED-Ed LOL, you erased the manatee, which, it turns out, is a pretty tough critter if people don't run them over with boats... and possibly if they don't eat them? I assume they're good eating and people hunted them... but, anyway, lol, they didn't disappear they showed how tough they were when people became aware of their plight, similar to bald eagles but only stronger, IIRC.
I have commented on the last video after I watched this one. But my name hasn't appeared yet
And the answer to your question is yes
Fantastic illustration and animation on this one.
This is my favorite channel ever! The animation is beautiful and the lessons are definitely worth sharing! I just enjoy learning new things and this channel explains concepts so thoroughly. The narrator's voice is soothing and is actually interesting to listen to (unlike my history teacher's🙄)! Like I said before, this channel is a wonderful domain on CZcams and it is an inspiration to my ears and mind.
I agree!
ughhhh!! REALLY!!! I just did a project on invasive species and searched to see if Ted-ed or Ted talks had anything about it, and there was nothing but now they do this video AFTER I'm done!!😒😲😲😡
Conclusion : do everything in the last minute
Now you've learn your lesson: procrastinate.
+GGSLM Just like my life quote: Just do it! l a t e r
Mm so dont do anythi ng until de last hour den u LEARNED UR LESSON dont u know u r supposed to PROCRASTINATE!!
lmao sad life xD
First of all The animation and art in this episode absolutely beautiful, second of all I thought Australia had lots of predators, you learn something new every day.🤔🤨😶🌫
Never in my life would I think "Australia" and "lack of predators" would be in the same sentence.
Most Australia’s large predator species are extinct.
my science teacher just posted this on google classroom because WE’RE GOING ONLINE NOW-

Same
do we have the same teacher
i’m allergic to cats idk 😂😂
Same
Amazing animation and interesting subject to talk about. Bravo!
Beautiful animation though.
We technically are but we've been in our current places for so long, and molded the environment to shape our needs that we're more like those really rich and obnoxious neighbors who think that they own the neighborhood
I have a feeling that most of these problems could be solved by simply returning all the species that once existed in their native ecosystems. The Everglades has very few panthers, which I think could adapt quickly to kill a large slow snake, much like the tigers in Asia. Australia has also had a removal of many of it’s native carnivores. The smaller carnivores e.g. quolls, have been reduced by foxes and cats. But dingoes are unaffected by these small carnivores and could actually help reduce their numbers. If we reintroduced dingoes they would eat foxes, cats, rabbits, etc. We could then reintroduced quolls that would add more pressure on the rabbits. I don’t think complete removal of invasive is realistic, but we can help fit them into the environments they invade.
The animation in this video looks so damn good.
Nice, this must be about the fourth time someone praises the animation in this video. Kudos to all that came before and all that will continue the struggle🍻
The art in this is beautiful.
The animation here was beautiful.
ted ed is the literal best channel for school and for if you're curious and want to learn about things, not even gonna cap.
It’s sad that we are a invasive species. 😰😥😓😭😢
the ending was just amazing
Wow, love the art design.
"Are we an invasive species!" - I could see that coming from the start of the video. Haha
The last line is an eye-opener .
Are all species invasive? Yes! In fact invasiveness is a life most appreciated feature! Without that we wouldn't know nature as it is!
"Are we a invasive species?" Yes, the answer is yes.
Not all humans are invasive. Native Americans, Africans, and Australia aborigines aren't invasive. Don't blame it on all humans. There's a certain race or individuals who might be invasive.
+FussionBomb no but humans as a whole are invasive. Some individuals might not be but our civilization thrives at the expense of our environment
the "noble savage" is wrong and an ill-informed idea. Europeans are not evil, and yes your comments are racist.
humans are not considered invasive because we are not an ecological threat to our self
Well we do hunt animals to extinction, wear animal skin for fashion sometimes, make nuclear weapons, pollute the environment,etc.
So I think it’s a FACT that we’re an invasive species.
Dude the art in this is so good
Very Informative, Thank you!
I always enjoy your videos. Gotta say I enjoyed this a bit more.
Here's one that's hard to swallow, house cats are considered invasive species in Australia because they decimate the bird population.
There is one diference between humans and other invasive species,
Humans cannot and will never adapt to the places they've inhabited, instead we will keep adapting the places to fit our whims, when non-technologic invasive species will eventually settle and be an active part of the new ecosystem they have contributed to create.. Basically, drastic change but in the end, the species will end up working together..
We never work WITH other species, we use them and it never benefits them in any way (on the long term).
Wrong, we know humans have been evolving for A very long time. It doesn't happen overnight buddy.
Robert MacKinnon when did I say it happened overnight? Humans have been using tools for 2,5 million years and have started killing big animals with weapons 2million years ago..
And in all that time, instead of adapting to the environments and creating more diversity working with other species like pretty much any other species would have done, we’ve just made war to the rest of the world, amongst ourselves, amongst other species of hominids that we be driven to extinction and most importantly against life itself..
There isn't a single species in the history of life who's been doing so much damage to biodiversity and for such a long time, usually invasive species remains invasive for between a hundred years to a few thousands, it never last several million years..
As always, TED Ed makes awesome 😎 videos! 👍👍👍👍👍
Cool, I learnt this while taking the SBA.
Not only THE invasive but the caller to the others
We tend to the Earth. It is our choice to be either destructive or a keystone species.
+Red_Jacket yes finally! ughhhhhh humans are not mere animals...
Teresa Wolfe That is what makes us sentient. Choice.
Love the question at the end
this is a very nicely illustrated video 😊
That hit me... Are we an invasive species!!!!
And because that's true...yes we are.
The last sentence was GOLDEN.
I love the topic of inasive species please make more videos on Invasive species.
excellent video 👍👍👍
Indeed we are an invasive specie

hey Ted ED, ya'll think you can do a video on the communication of wolfs ( like how they can chose leaders but his or her strength or intelligence, or how some hold their heads high and others tremble before their elders) , there is so little known about them, so if others find out about it, then maybe they will think of a question with more than an awnser
the ending is mind blowing.....
Wow we mess jack up don't we.
+She Dragon is correct.

Keep up the amazing work ;)
I live in the amazon forest region and I hate when people bring plants from other states, I keep imagining the worst thing happening.
How many times do people look at nature and think negatively while the person themself caused the situation?!
4:26 YES.
4:18 To cite Agent Smith from the documentary The Matrix: *I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species. I realized that you're not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed. The only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet. You are a plague, and we are the cure.*
+2nd3rd1st smith was taking several poetic liberties there,
Every mammal on this planet instinctively develops a natural equilibrium with the surrounding- as the australian rabbit demonstrate this is no true all animal reproduce until limiting factor reduces that growth.
You move to an area and you multiply and multiply until every natural resource is consumed. The only way you can survive is to spread to another area. - show me a place where humans have consume every natural resource and then move , there is none humans stay in one place and then modified to be more fitting for there life Africa has had humans since human where a thing and still has humans same for Europe. you know the only people that act like that nomads that is why it is okay to kill nomadic people like gypsys . /s(only applies to that last sentence)
+marlonyo I didn't write that 17 year old movie, hombre. Argue with the Wachowskis. ^^
2nd3rd1st no by using the quote you are tying yourself to it. the wachowski did not write the comment they did not brought the quote in this context you did own up to it .
Best closing statement
That ending twist though......

A great video. Thanks.
Thanks for coming to my TED Talk
i was actually thinking of commenting that question at the end
That last line: "Are we an invasive species?" *WELL NOW I HAVE TO QUESTION EVERY SINGLE THING I DO!!!!!*
Super Awesome!! I learned a lot! Thanks
1:50, that pause felt like being told "let that sink in"
Are we an invasive species? my answer: yes, we are. The question then becomes: is our invasiveness a bad thing? That's a debated where science and philosophy cross each other. My philosophical view is that a species will do anything to ensure its survival short-term or long-term, short-term being immediate threat to one's life (fight or flight) which all animals know very well, and long-term being to plan ahead to ensure survival, be it reproduction or changing patterns in behavior to prevent or enact something to benefit oneself andor its species. In terms of human survival, all we're doing by invading ecosystems and effectively establishing our own (cities), is ensuring our survival. I believe our ultimate goal is to reach space and thrive there. This planet will die one way or another, and humans need to eventually supercede this Earth to ensure our survival. Maybe a radical idea, but a relevant one.
+Joshua Guillemette Its the same as always; eat or be eaten:
And I prefer Eat;
Radically disrupting the balance of the entire Earth ecosystem is not in the long term interests of humanity, but we are, nonetheless, engaging in just that activity. Yes, we must eventually leave Earth to ensure our survival, but we won't have the tech to do this until well after our environmental problems at home become extremely dangerous.
+Joshua Guillemette But are we really ensuring our own survival? I think not completely. A big portion of human activity is harmful for our environment, other species and ultimately us. Sure, Earth would no longer be existent one way or the other someday, but we are certainly shortening its lifespan.
I would say invasive species even humans are a double edged sword.humans destroy and kill off man species while also helping others on propose or unintentionally.we've also set some new possible species to evolve in motion.
+Kingdomonoob l agree. If I believe correctly, the meteorite that wiped out the dinosaurs actually destroyed more ecosystems and caused mass extinctions on a scale so massive, it will make our own mass extinction currently own the earth seem like a natural occurrence.
Though I think this was just a theory.All I know is that the mass extinction of dinosaurs also destroyed many other ecosystems as well.
someone show this video to Johnny Depp
Lol.
why ?
Cause of the dogs his wife brought in.
lol similar attitude between the 2 isn't it! Anyway, all is good, Australia got our moneys worth out of that viral quarantine advertising campaign :D (kinda ironic when you think about it, for a government to to run a VIRAL campaign on QUARANTINE lol)
