Invasive species are non-native organisms that disrupt ecosystems by outcompeting native species for resources, predating on them, or altering habitats, often introduced accidentally or intentionally by humans and causing significant biodiversity loss. Examples include cane toads in Australia (200 million individuals), Burmese pythons in Florida (90% wildlife decline), feral cats in Australia (1 million native birds killed daily), and brown tree snakes in Guam (7 of 18 native species extinct). These species demonstrate how human-introduced organisms can devastate entire ecosystems through predation, competition, and habitat destruction.

Reacting to The Invasive Animals Destroying the Planet By Good EnoughAdded:
Hello, hello everybody. Today we're checking out a video by Good Enough.
This is invasive animals destroying the planet.
>> Let's start with the animals that are collapsing ecosystems.
>> killing us?
If you count this as an animal, we are killing us.
Number eight, silver carp. Silver carp are some of the most destructive invasive fish that can infest any body >> kind of ugly. But I must admit, it's the only invasive animal on the list that is actually funny. We've all seen the videos Oh, I missed them.
Ah, these ones.
Yes.
They do?
>> [laughter] >> Ah, true. Yes.
Ah.
Brother.
Everything.
Oh.
How do you do it?
A sport?
With a gun? With an arrow? With what?
You just shoot fish with That is crazy.
I think Do they taste good?
Okay. for overall health.
>> Which is exactly The the Yeah, that's exactly what the Americans don't want >> reason Americans don't eat it.
>> Yeah.
>> Number seven. That joke just writes itself.
>> Invasive cane toads are some of the most destructive animals on the entire planet, and in many But but they look They're so ugly.
>> cases have single-handedly vast entire ecosystems. I thought is native to South and mainland Central America, but thanks to humans, they have been introduced to various parts of the world. Well, let us take a look at Australia.
>> Wait, how who who brings toads somewhere else? Toads are disgusting creatures.
Why you even touch or bring or get a toad?
>> Since it's perhaps the place that has been the most devastated. In 1935, 102 cane toads were released into the wild in hopes that they would eat the cane grub, a small larva that was decimating sugarcane crops. They ate it. must have just taken a look at their names and figured that the cane toad must eat the cane grub, since their names were practically a match.
>> Yeah. But as it turns out, the cane toad eats just about everything from birds, insects, reptiles, rodents, and even dog food. But the one thing they don't eat, you guessed it, are the cane grubs.
The one thing they were supposed to eat, they don't eat. in the scientists' faces. They wouldn't even prefer trash before the grubs, Why?
>> the scientists yet again how much of massive >> Why is the last thing they do that I like?
>> [laughter] >> they are. Today, there are around 200 million cane toads in Australia, and that number is only growing. Now, Bro, wasn't it Australia that had the rabbit situation where they invited rabbits to take care of something, and then the rabbits started the rabbiting and there was a a lot of rabbits, and they couldn't get rid of them?
>> take a look at the cane toad Oh my you might think, "Not bad. Solid forearms, great traps, and decent lats.
But makes the common mistake of ignoring half its body. What?
Not small legs.
It's not.
Crocodiles?
Wow.
Why don't you introduce them to the French, then?
Oh.
Is this the native Australian man? Is this how they look? Or maybe this is the native Australian woman, I don't know.
I never did.
Are they still alive?
I knew it.
Hey.
It's still don't kill in Australia.
Let's go.
Australia.
Bro.
Do not.
Oh my God. destroying the entire ecosystem of Australia by consuming the majority of the vegetation leaving very little for the native animals.
Australians tried their best to hunt as many of the animals as they could. But no matter how many they killed, it wouldn't come close to making a dent.
When they do enjoy life, that's a lot of babies. So instead, the Australian government turned to bio-weapons. In the 1950s, scientists released a rabbit-specific virus called myxoma virus, which wiped out a good chunk of the population. But eventually, the rabbits developed immunity to the virus.
So again, in the 1980s, scientists released a new targeted virus. This time, it would be rabbits manual thing. They just get stronger.
which only took 48 hours to kill and would end up eradicating 90% of the rabbit population in many areas. But once again, the rabbits began to develop immunity. Today, this game of catch-up continues and there are still over 200 million rabbits in Australia happily destroying everything they touch.
Rodents. Why does it always have to be rats? Probably the most obvious pick on the list and easily the most annoying are rats and mice. These disgusting little pests have been following humans around the world for at least 15,000 years. But who can blame them? After all, humans leave behind the best loot.
Now in the majority of cities and towns, rats and mice are just a nuisance. But of course, in places like New York, they're just roommates.
The place where rats and mice have caused the most destruction is actually on islands. For example, islands like Hawaii, Galapagos Islands, and New Zealand have seen a massive decline in their wildlife and forests since rats and mice arrived. New Zealand alone has lost 40 to 50% of their bird species and many more are currently facing the threat of extinction. This is because rats consume the majority of the native animals foods like insects, seeds, and fruits. But of course, they also eat the animals Yo, the way he pictures these animals.
I would like to look into his mind.
>> themselves. And when animals finally build up the courage to eat the mice or rats for a change, it quickly backfires since lots of them getting sick from a deadly disease skyrockets. Now, even though many animals eat rodents, they reproduce at such high rates that it makes it impossible to eradicate them completely. Number four, Burmese python.
The Burmese python, one of the largest snakes in the world, only behind the terrifying anaconda and reticulated python, >> Anaconda. native to Southeast Asia, this snake would make its way into Florida in the 1980s thanks to exotic animal collectors. You see, originally these exotic owners only saw a snake that only required a baby mouse or two to survive. But eventually, the snake would grow larger and larger requiring a bigger and more expensive meal like a rat or bird. And eventually, a Chipotle burrito. So realizing that they're slowly going broke and losing hope that someone would someday say, "Cool snake." they come to the logical conclusion of simply Throw it in the wild. releasing the snake >> Yeah.
That's what they do.
everyone else's. Today, there are tens of thousands of Burmese pythons in the Florida Everglades consuming just about anything that moves from birds and mammals to alligators >> Wait. Wait. How big do these things get, bro?
>> crocodiles. And in some parts >> They consume crocodile? Everglades, animals have declined by over 90% after the snake arrived.
Today, many people in Florida hunt these snakes as a full-time job, earning as much as $150 for every 8-ft snake they catch. The difficult part of this >> Wait, that does not seem worth How many snakes can catch a day? are some of the best at hide-and-seek, since they love to hide in dense vegetation, underground, in the water, and even in the trees. Oh, yeah.
When you least expect it, these snakes could find and tag you.
>> Huh.
Since it's not uncommon No. way through plumbing systems and into toilets. Even though Florida memes are funny, we have to give credit where credit is due.
Florida can hang their alligator skin hat knowing that they are currently in first place for having the most amount of invasive animals on the planet.
Number three, wild pigs. This is the only animal that I've encountered first hand. And trust me they are as mean and disgusting as they look. They're scary.
threatened to charge at me up close.
>> Okay, I don't want to have that. Look at my insane physique, it of course cowarded out by not chasing me.
Nice. Wild pigs are native to Eurasia and parts of North Africa, but were brought over to the US, Australia, and Europe as a food source. But you will never guess what happened next. They escaped. And in the wild, their numbers [laughter] quickly exploded. One interesting thing to note is that it took humans thousands of years to domesticate Okay.
wild pigs into the smooth and gentle pink giants we see on farms today. But if that same pig managed to escape into the wild >> Yeah, it goes back.
it would revert back to its original form and look like this. Which is wild.
>> me sick just looking at it.
>> Yeah.
A wild pig can grow as large as 150 lb.
And before you say, "What about Hogzilla? He was much larger." But that was nothing more than a cheap and disgusting perspective trick that hunters like to abuse, making the animal look much larger. Of course, I only do this when holding a fish. After all, how else would I convince my friends that I know what I'm doing? Now, let's talk about why these animals are so I hate fishing. So boring. For one, pigs are omnivores and opportunistic They eat everything.
feeders. So, they will eat pretty much anything, Yes. leaving nothing behind for native >> They don't care.
That's why they're pigs. is rooting, where they dig into the ground to consume the plant's roots, which destroys the soil and kills native plants, preventing them from growing again. Another terrible habit that pigs have is wallowing, where they roll around in the mud next to a water source, contaminating the water with bacteria, diseases, and parasites, which affects the native wildlife that drink the water. Now, here in America, farmers and landowners are sick of these pigs and are fighting back the only way we know how, which is by shooting them with high-caliber machine guns from helicopters. After all, >> [laughter] >> God damn it, America.
Now, >> I don't know if that's badass or stupid, so I'm going to put it in the American category of both. Lucky them. Yes. It looks awesome.
Oh my god.
We came. The brown tree snake is a mildly venomous snake native to Australia, Indonesia, and Papua New Guinea. But, during the 1940s, the US military accidentally brought the snake to Guam, most How? shipping containers or in cargo. Today, there are around 2 million of these snakes on the island, or around 3,000 snakes per square mile, making it almost impossible not to run into them. Here on the island, picking up common items like tree branches, logs, and cords are all a frightening game of roulette.
The brown tree snake is the only species of snake on the entire island, which hasn't allowed enough time for the native animals to adapt accordingly, leading to seven out of 18 native birds and animals to become extinct, permanently changing Guam's ecosystem.
But, not only are these snakes eating all the native animals on the island, they are also constantly causing power outages since they love to climb on transformers and electrical lines, causing them to short circuit.
Today, US authorities are fighting back by using helicopters to drop thousands of dead mice onto the trees for the snakes to eat. Free meal comes with a deadly amount of painkillers, which are put inside the mice, causing the snakes to die soon after eating them. But, only time will tell if this proves to be an effective way of controlling the snake population. What the Okay, how do you come up with this? Let's have dead mice poisoned and helicopters combined. Throw dead mice that are poisoned from a helicop- What? before all the native birds and animals are completely wiped out. Who thought of that? feral cats. Who would have thought these cute and cuddly animals would be capable of so much death and destruction? Everybody.
They They are monsters. Just because they're cute don't mean they're monsters.
>> Well, Look at women. anyone who lives with one could have told you that. Yes, the deadliest and most destructive invasive animal in the world was right next to us the entire time. And in all honesty, we should have seen this one coming since all the signs were there.
To see just how much of an impact cats can have on an ecosystem, or in this case, an entire continent, we just have to take a look at Australia in the 18th century.
Australia, are you guys okay? Are you okay? Cats arrived in Australia on ships to help manage the rat and mouse populations. But, over time, cats got sick of being around humans and figured that starting a new life in the Australian Outback was a way better option.
>> Wait.
Cats hate Australians?
Damn, Australians, y'all must suck.
>> And in no time, the feral cat population exploded. Today, there are anywhere from two to 10 million cats in the wild and are directly linked to the extinction of many native species and the endangerment of hundreds more. And since cats have no natural predators and many options for food, that number is only growing. It's estimated that 1 million native birds and reptiles are killed every single day by feral cats and well over a billion animals every single year, making them the deadliest invasive Crazy kill count.
So, in an attempt to lower the feral cat population, authorities are deploying poison baits in areas with high concentration of cats. [music] And in certain areas, hunters are paid to trap and kill the animal, being paid $10 per cat scalp.
What?
Okay, that but I don't Now, another tactic that is being implemented is simply giving up, creating a 27-mile cat-free zone by enclosing it with an electric fence to protect native animals. Essentially, You think you can stop cats from going somewhere? You're dumber than a toad.
>> them with a little safe haven.
>> You cannot stop cats.
>> security prison.
>> [laughter] >> You cannot stop cats. If cat wants to go somewhere, cat goes there, okay? Anyway, um let me know what y'all think about this video. I know I have some people from Australia. What's up, bro? What What are you guys doing? What is happening over there?
Huh?
Damn.
Uh anyway, like or subscribe. There's a playlist with similar videos and I'll see y'all next time. Bye, everybody.
