Why the US Army electrifies this water

- Опубліковано 21 сер 2022
- The Chicago and Sanitary Ship Canal is the path that invasive carp would take to reach the Great Lakes. So to stop them, the US Army Corps of Engineers has installed an electric barrier. Although for obvious reasons, I didn't get to see it close up. [The interviewee is project manager Jeff Zuercher, whose name caption got missed out! Apologies, Jeff.]

I hope the carp don't figure out how to dig a tunnel past this. Those carpal tunnels can be wicked.

Baha classic! 😂
I've heard carp'll tunnel, but it can be prevented with a wrist-rest.
Booooooo
Don’t be koi, Max.
If you said "Guess why you can't kayak from the Gulf of Mexico to the great lakes." none of my guesses would be "because of a deadly electric fish barrier."
I mean you could still do it, youd just have to go the long way down the St.Lawrence river
How about finding a way to keep snakes from the Amazon from swimming to the Everglades?
@@rcschmidt668 😂
You’d wanna start at the Great Lakes. Otherwise your paddling up stream
The guy said it only stuns the fish so how would it kill a human
It's a constant battle. The Great Lakes are also constantly fighting other invasive species like Zebra Mussels. They're non-native and mess with all kinds of things. I believe they arrived in the ballast water tanks of large ships.
Zebra mussel has been plague for at least 30 years as far as I’ve known.
It's true. The zebra mussels have made their way all the way down to the lakes and waterways in and around Austin, Texas. The mussels collect around water intake pipes of the municipal drinking water supply, reducing intake flow. Their microscopic eggs make it past the initial filters have to be eliminated chemically (copper) and additional filtering stages are required remove the smell of decomposing mussels
They plug up our waterlines at work all the time. Coincidentally from the location featured in this very video albeit I believe it’s a mile or so upstream
I think we have bigger issues to worry about. Social justice for one, diversity and inclusion another.
@@fjb3544 did you know that it is possible to care about multiple issues at the same time?
I was the engineer on a boat that regularly passed through here while the barrier was being built and later while it was in 24/7 operation. The narrator is telling it like it is; we were not allowed on tow or on deck while transiting the barrier. I understand that a second barrier is to be built on the downstream of Brandon Road Lock in Joliet, as well.
They have highway style programmable warning signs above and below the barrier, my crew wanted to hack the signs so that the last line it displayed was "FISH FRY TONITE!" 🙂
is it really that interesting? 🤷
Making the signs say Fish Fry would be hilarious.
Did you read Captain Underpants growing up? This strikes me as very George and Harold.
I already had my USCG engineer's license before Captain Underpants came out!
Anyway, we had a lot of fun joking about it. :-)
@@domingorodriguez3077 yes it is, unlike you
One interesting thing not mentioned: the local paramedics have been given a 'no rescue' order. If you foolishly go into or near the electrified water and become injured, no one will come save you. The risks to the rescue personnel are too high.
so basicly this deters hopefully even more people because if you try it you will die and we wont save you.
they should have possibly also added the recording of your death will end up on liveleak
Woah that's insane

“US Army Electric Fish Barrier” is objectively incredibly funny and just seems like one of those web titles you’d see in Futurama as a headline for a news paper
I asked

We DO live in a Futurama'esque world.
Some random wanna-be dictator was elected president of the USA, made conspiracy theories widely accepted "facts" (over 50% of the US population believes his BS), violated dozens of laws, instigated an coup d'etat, broke national security (nuclear weapons documents at home, awesome)... and has real chances of being re-elected in two years.

I find it ironic how the little plant behind Tom is an Ailanthus altissima (chinese tree of heaven) - an invasive species that is an entirely different problem of its own and how it isnt bothered by the huge facility for preventing IAS spread its growing on.
Asian carp have ruined the fishing and water quality of so many lakes around where I live, I shudder thinking of how catastropic it would be if these fish get to the great lakes. Thanks Tom for helping to raise awareness about this huge issue!
when they found one carp in lake michigan they dumped 3 tons of poison into the part they found it in just to be sure.
the solution is simple: bears! lots and lots of bears! and then chimps to befriend the bears and groom them to remove any eggs in a symbiotic relationship! what could go wrong? nothing, I tell you!

One of my favour parts of these videos is seeing the control systems for the processes. I work in industrial automation and very often have worked with things like the computers and instruments that are just a background element in the B-roll. I believe in one video it's stated that that really isnt' where Tom's interest lies, part of me enjoys that a bart of the videos that I am intersted in get no additional detail.
It's so exciting to see those systems isn't it?
Why do you enjoy that there is no additional detail about your interests in the video?
@@jessesleight9631 maybe it's knowing you're a mystery to everyone else
@@jessesleight9631 I think it's partly wondering about the solutions myself, how I would be trying to control the systems or what about them is important. Also partly it's kind of par for the course for controls work, even the people who work closest with us don't really understand what we do.
In just four months, this has become one of Tom's most popular videos. Good Job.
There's something magical about reading the words "US ARMY ELECTRIC FISH BARRIER" on a GUI, and also knowing that it's powerful enough for just standing near it to be at least mildly concerning for a human.
2:20 if anyone wanna missed it
A greater than 50% chance of cardiac arrest is more than "mildly concerning"
@@flyaround312 the cardiac arrest thing was when someone entered the water. The "mildly concerning" part was clearly not referring to that.
I hope whoever designed that GUI was giggling inside while writing that
When something has enough electricity in it to hum like that, it's also very ready to arc off into your car keys, your glasses, your bone fracture plates, or just you directly if you get close enough. Why more birds don't cook from landing on wires is beyond me.
For anyone interested, a similar barrier has been proposed for the Suez canal in Egypt, to prevent fish from the Indian Ocean come to the Mediterranean. This migration is apparently facilitated by rising sea temperatures, and invasive species are already making a dent on the fish of the great Med. Most of them are inedible too (or even toxic to humans) so this is also a potential economic disaster for millions of people.
@@mdrafiqul2898
You are so funny that I threw up…
@@mdrafiqul2898 The ocean being named after a country is still bizarre to me despite being indian.
reading the available literature, it appears that no electric barrier is ever 100% effective. But to be effective as a fish barrier, it would have to be 100% effective. Ergo, they are all boondoggles; wastes of the taxpayer's money. At best, electric barriers can DELAY the inevitable conflict by a few years tops.
@@apetogetherstrong4243 I never really thought about it, but that is weird. Even if it was named for the Subcontinent altogether rather than the country, that's still unique since all the other oceans aren't named after landmasses like that.
@@lukeothedukeo most oceans aren't small enough to be encircled by a single land mass. It's like if we called the gulf of Mexico the Mexican Ocean instead
I work at the refinery attached to this place and Its so cool to see someone I watch regularly on UA-cam film where I work and make a video about things that actually directly impact me.
Hey anyway I can get into that refinery I’m a photographer that’s been wanting to take photos in there for ages
This was really fascinating! Thanks!
So many interesting stuff everywhere. Just need to learn about it. :)
One of the safety rules I had to follow while filming was "don't touch two different metal things at the same time", just in case of any stray voltage. That's how powerful the barrier is.
Rules huh

It’s incredibly scary to think what would happen if these defenses fail. Been unsettled by this ever since I learned about the carp problem. And I’m not even from the US
good thing terrorist are stupid and don't go after fish infastutere.
right?!
People adapt and things change. This is just a huge waste of money to be honest. Too big to fail nonsense.
This is such a funny example for how seemingly small mistakes sometimes require literally giant solutions
Just stuns them. For a minute, I thought the Army Corps of Engineers had actually created the world’s largest fish fry .

There's a reason Tom's boat is surrounded in netting.
And that is just at canoe speed. When going at speed in an average personal craft, it can be lethal 🤷♂️🤯
That'd be enough to put me off wanting to canoe there again in the future...
I think stories like this are such good examples of unintended consequences. Both the problem and it’s possible solutions come from long lists of potentially spiraling unintended consequences
One possible extreme measure not yet taken is a full on dry span with conveyors, dragging barges out of the water, over a mesh barrier and through pressure jets, into the other side
I remember when they were setting this up. that was a scary few years. A lot of people thought it was too late. At one point they found a carp in the lake, so they literally poisoned a several mile stretch of the lake, killing everything so they could examine all the fish corpses. I dont remember if they found more. But these barriers couldnt go up fast enough.
Ironically the lake is now being killed by clams. The water has never been cleaner, but they're apparently causing problems for other species
As for closing the canal. It might be the right choice, but it will never happen. Chicago doesnt exist without the canal. I honestly believe they might go as far as poisoning the entire river before they closed the canal. It's that important to so many industries across multiple states.
Clams are far easier to deal with than massive jumping Carps, so that is a close victoy.
@@TuWear in a normal stretch of water this would be true. There is no fixing the great lakes. They're simply too massive. If an invasive species gets in, we aren't what will make them leave. Even with magnitudes unrealistic effort, there is nothing we could do
zebra mussels are (getting) in(to) the great lakes too, aren’t they?
@@m0rg4n1sm yes they are!
@@TuWear how do they get rid of the clams?
There is no rescue plan only a recovery plan. Is what I was told if we fell into the water as a sub contractor on this project. There's so much electricity pumped into the ground that the nearby railroad track crossing would open randomly. Coolest project I've ever been on.
Wow that’s crazy about the railroad track
so how does this crossing then operate? And if someone fell in, well maybe briefly switch the thing off?

SImilar thing happened here in Australia in the 1930's, Sugar Cane farmers had problems with cane beetles, they decided to import the cane toad to deal with them. Unfortunately the toads were not interested in eating the beetles, and now we have plague proportions of cane toads that have decimated the native wildlife of the areas that they have invaded.

Very interesting segment. I had no idea electric barrier existed.
Thank you Tom! Always so interesting and well presented. Sad how many times human-kind's best intentions have resulted in catastrophe (spitting atoms, an' all that).
The problem with the Asian Carp and the Great Lakes is that they arent just in the Illinois River. They are also making their way upstream from the east into Lake Erie, which presently lie unprotected...
From what I've heard, they're already a problem in Lake Erie.
They've been in Lake Erie for a long time.
Yup, already been in here. Most fisherman know if they catch one, they kill it on the spot.
I like fish, so many I should take up fishing as a hoby.
Grass carp are all over Lake Erie. They are trying to eliminating them by targeting their spawning grounds in the Sandusky and Maumee rivers. But they have nothing remotely like the insane concentration you see in this video in the Illinois.
As a person who lives 5 miles away from this I did not know this was in fact electrified. Thanks Scott!
I mean, if you went there, there would be signs and stuff.
@@SushiVolcano If you went there, I'd imagine it would be quite shocking.
I live in Lemont IL and I’ve been along the canal bank. There is a sign that says “NO HUMAN BODY CONTACT OF ANY KIND ALLOWED”

Go dip your toes and tell us what it's like.
Dude I didn't know you were in Peoria. I live here. That's awesome. Hope you had a good time.
My dad worked in Chicago and helped reverse the water flow. He helped dig and build tunnels.
I used to be a tour guide on the Chicago river and we would talk about these fish. The lakes also have a zebra mussel problem.

@@jfrog1979 Why? He doesn't even know he's President.
I've actually gone hiking many times right by the Illinois and Michigan canal, sometimes starting in Romeoville, Illinois. I never knew about invasive carp or the electrification of the canal, but I will say I did consider tresspassing and swimming in the canal for fun with the ships. I'll definitely be rethinking that idea. Great video.
I would never wanna swim in this canal lmao. The water is so nasty
Swimming with ships is a bad idea whether the water is electrocuted or not
Trespassing and swimming with ships are unwise decisions regardless of any other factors.
Trespassing and swimming with ships can be a very enjoyable, safe experience. Try it after dark, you'll have a great time

Being native to the area surely means you have a higher-than-average resistance to electricity. You could probably swim around in there all day an not feel a thing :O
I actually worked on this job site before. If you drop a tool on the ground you have to pick it upin a specific way to avoid being shocked by excess current.
What specific way? I'm curious
Is it picked up like from the tip to bottom instead of all at once in the center?
Making sure you're touching only ONE metallic object?
That's shocking.

Do you know if they investigated a bubble curtain at all?
@@geopolitix7770 That was actually the last test we did in October. The Corp used 3" pipes with .187" holes ever 2" placed perpendicular to the river flow at the head and tail of the lock.
There was talk of using some thing similar to a fish tank aerator, the little stone thing on the end, but at the rate in which air would be supplied to make an effect there was a significant loss in bouncy, heading into the double digits and there was major concern when the lock is closed it would increase exponentially and causing damage to infrastructure.

That electric grid in the water is terrifying and I'm sure effective. I say terrifying because I had a friend years ago killed by being electrocuted in water. Faulty wiring on the boat dock, he dropped something in the water, went in to get it, horrible way to go. I wasn't there but I still get emotional thinking about that whole mess.
I’m sorry about your friend, I hope that in time, you can heal. ❤️
Sorry for your loss🙏

not an electrical grid
I'm an electrician. All my bosses and most of my friends are gone, I've seen many men die. This is 6 volts. Your buddy was killed with as low as 120 volts, or 208, 240 volts maybe as high as 277/480 volts. All are lethal. We try really hard to make sure what happened to your friend doesn't happen, but it's a matter of budget and will. The owners or operators don't usually understand the risks, become complacent, fail to test and maintain, and people die or get severely burnt or disfigured. 50,000 electrical fires in the US each year, 135 a day, not including electrocutions.
I appreciate Tom’s professionalism. Cruising UA-cam watching funny things is nice, but every now and then these informational ones done very well are a nice refresh.
I agree!
Get reported
Maybe they should add a locks system where barges stop in the middle and they pulse the water in that middle zone with extra voltage a few times to make sure even smaller fish are knocked out. The locks could also double as a maintenance system, allowing them to block off the waterway entirely when the electric barrier needs to be serviced.
And you don't think they considered that?
@@StanSwan Maybe they have considered it.
i live in Ontario and we have carp in our lakes already, specifically in georgian bay which is connected to lake huron.

@@toxicvillain ?
As an engineer, being able to actually explain what we do to people outside of our profession is a skill that not a lot of us have.
A barge conveyor that lifts the barges out of the water for few yards would seem to be one option. It would work in the same way that a River Rapids Car Lift works. It wouldn't slow down barges, but might not work for other sorts of watercraft.
A carp could probably survive that much time out of the water
I remember lake ontario having a lot of big carp near the pickering power plant in the 80's, I would assume they are still there today
Finally someone of decent size commented on this. Believe it or not, my father got knocked out from an Asian carp jumping out of the water on the Illinois around the time this started. The things can get huge (by Midwestern standards).

Nice! We've got invasive carp here in Australia as well; it's on a smaller scale, because our rivers are smaller and more isolated from one another, but it's still bad. There's a control & eradication program running, and as a by-product of that you can get carp-derived plant fertiliser for quite cheap. That part is nice, at least.

I am really comfy knowing all that stands between me and these things is... Chicago.
I think the idea of adding miniature "locks" makes a lot of sense. Bring the barge in, shut the door, shock the crap out of anything in the water with EXTREME voltages, the open the other door and send it on it's way. If power goes out, the door is still there. A few strategic high pressure pipes/gates will keep things out of the lock area when not open and maintain water flow.
Good idea, and give cathodic protection to the metal pipework
Those barges can't afford to stop for a do-nothing lock, let alone a bunch of them. Your idea makes zero sense.
It would be too slow for trade. In the world, USA especially, time is money.
Locks like that are in the great lakes, sure to hight changes Lake too Lake.
Wouldn't be too much of an issue to add the electrification.
@@oaktadopbok665 Many canals use locks, the Panama Canal for instance, and the Grand canal in china. The amount of time spent in these places is not much more than at a regular checkpoint.
It would slow things down a little bit, but not that much, especially if they set up multiple locks to deal with multiple barges at a time (which probably isn't even needed for this particular canal)

From what i know carp is just an invasive species, which is why people can overfish them, but at the same time they build lakes and breed carp in there specifically for fishing
Wow, I never knew it was that serious and close to the great lakes
As a habitat ecologist, I HATE those 20th century American planners for their arrogance and hubris. They introduced countless invasive species as “solutions” to solve simple problems they were too lazy to deal with responsibly. So many amazing ecosystems across America have been utterly and irrevocably destroyed because of invasive species introduced by 20th century planners. My local ecosystem here on the Texas coast is Gulf Coast Tall Grass Prairie. There used to be 6.5 million acres of it here in Texas. Now over 99.9% of that habitat is lost, thanks in no small part to invasive species such as the Chinese tallow tree and various South American grasses.
Kudzu and ice plant also spring to mind.
the native americans probably strongly agree with you, those invasive species ruined the place.
USA!!!!! USA!!!!! USA!!!! USA!!!!
Well they took the fastest and cheapest method, im not sure if they could even really know what would happen to the ecosystem 100ish years later. But hey it’s politicians who most of the time worry more about the next elections than about the future of the country so who knows if they would even care if they would have known it back then.
Uncaring hobbyists introduced crayfish into our stocked and controlled fish ponds and now it's at the point where you can just stand on the side of the pond and haul out dozens and dozens of them. It's at the point where there's no rules about how many you can capture, just so long as you kill them on sight. You could sit on the shore with a hammer and just mush them up and fish n wildlife would just ask if they could bring you some water or coffee. It's revolting how shitty some people can be
I work on the Illinois River pushing barges, for the same company that owns the towboat in this video. I am actually sitting just a few miles from the electric barrier right now. We have to lay grounding wires between the barges and the boat pushing them. The voltage is enough that a loose connection can cause an arc strong enough to weld the wire to the deck fittings. A connection with an inadequate wire such as car jumper cables can actually melt the wire.
Daaaaang!
Beat time to do your welding repairs on the boat then, free electricity 😁
If only one could use it…
But seriously: Wouldn’t it do any damage o on-board electronics?
Dont let any magic carp get onboard
@@demil3618 good question, but no. The hull and bulkheads of work boats is made out of 1/4" to 1/2" steel. All electronics and personnel are protected from electrical currents while inside. Any electronics on the exterior of the boat such as the radar and radio antennae are appropriately grounded. Smaller pleasure craft are not as adversely affected because they are not exposed to as much of the current due to their size, so it is safe for families to pass through the fish barrier, so long as they remain in the passenger portions of their vessels and do not make physical contact with the hull.
@@mark7362 the carp are rarely seen above Ottawa, but they are dealt with by the work boat crews with varying degrees of ruthlessness. Some guys simply kick them back in the water or blast them off the decks with a fire hose. Some use a sledgehammer to knock them off. I've seen one guy use a fire axe after a carp jumped out of the water and stole his cigarette out of his hand.
When they said the the switching equipment was dangerous, they where understating it. The gray boxes at 2:41 are capacitors. Those kind are so large, that touching their two metal posts would not electrocute you, It would make your muscles contract so violently, that your body, EVEN YOUR SPINE would be all over the room.

"We came here generations ago from waters far away, brought in by the land giants..."
There's koi that got lose into lake Michigan when the barrier failed. This happened a couple of years ago. We have Japanese carp running around the lake. Plus idiots went down to the lake and dumped the tropical fish in or flushed them.

As a Peorian, these carp are fun to watch when eating at the Steak and Shake in East Peoria, but I’ve heard stories of people being knocked unconscious from them. A few personal boats that go fishing in the Illinois have to have cages around their boats so that you don’t get knocked out yourself.

I assume they must have standby diesel generators, but you are right - there are always vulnerabilities. I wonder how long the barrier could be down for without creating irreversible damage. A week? A day? An hour? Scary thought.
Probably have back up generators.
It's so sad the damage that invasive species can cause because they were introduced as a quick fix to a problem. I'm sure that most Aussies know about Cane toads, but they were introduced to deal with cane beetles. Unfortunately their toxins kill a lot of native animals and they now can be found all over eastern Australia. Humans can make such a huge impact with small decisions.
I remember the Simpsons episode, but never looked into what it was really about
There's tons of stories of Australia completely screwing up their wildlife. The U.S. has sent over 20k people to Antarctica and they've harmed nothing.
@@raphaelrodriguez2774 I don't think they sell them in Walmart, I think dandelions are sold by packets of seed on the market stalls of Istanbul.
I wouldn't bother trying that again until November because the rat traps won't be in force yet.
Thank you though for your help, it really is appreciated still to this day, I'll never forget you.
Just another example of a long list of government failures...
The Australians have experience also with rabbits.
Amazing! Educated experts make decisions that are catastrophic.
"There is no way for the carp to get past this point." That's a good one dude!

The fish is like "heelloooooo"
12 years ago one of my Biology professors left mid-semester to take a position in Oklahoma to work on solutions to the carp invasion... while I continued in school I was surrounded by students and professors all studying and moving either up or down the river to work on it. Here we are. Interesting.
That’s really cool
do you like hamhocks or neckbones with your collard greens 🤔
@@sisigpapi super cool 😎
@@examtime2180 last ti.e we build an acme 5x24 series time transducing capacitor with built-in temporal displacements and AMD dimensional warp generator modules containing the grc79 induction motor...we have seen electrifying moments
@@examtime2180 lots of atomic weight in there waters...Xtra dimensional, isotopic matters...3 phase carp
Very interesting! thank you 😀
Seems like a risky proposition as it needs to be 100% effective at stopping carps. They will sure have redundancy but if that thing fails even for one hour, that's the end of it. I would definitely install a conventional barrier upper in the river.
This is one of those times where I think the over-engineered solution they've come up is STILL NOT ENOUGH. Given the risks and the weaknesses.
You have to keep in mind that this barrier was planned and created 100 year ago.
It isn't enough
@@xenitefufu1109 no. The river direction was reversed long ago to keep pollution out of the Great Lakes. The fish barrier is much more recent.
You can never over engineer for something that is irreversible.
Anyone got a spare trawler net?
The Great Lakes have already taken a beating from invasive species. In fact, the sport fishing industry on the Lakes developed in part as an effort to restore the ecosystem after previous invasions destroyed the commercial fisheries. The book "The Death and Life of the Great Lakes" by Dan Egan covers it very well.
and some people don’t know Carp are already in the Great Lakes. this definitely helps the influx, but they’re here already.
So fishing sport is helping the restore ecosystem?
And why not make it legal for everyone to fish theme and discard theme as they wish ?
@@predatorrt5632 Its a different kind of carp, but you are right.
Zebra mussels have invaded the Great Lakes and caused a ton of damage.
What a huge logistical nightmare just because some people brought some carp into the river.
has noone thought of just adding grated gates with grates that're too small to let fish through, but large enough that water can continue to flow along the canal
and every time a boat or barge comes through they just move the gate just enough for the watercraft to get through
that would be a reliable backup measure in case the electrical bits fail and would be simple to install, given it is literally just a thin metal door with holes in it
I worked for the illinois department of natural resources in 2009-2012 when the carp problem was at a fever pitch. Charters and recreational boating was at an all time low because the carp would jump into boats and injure passengers
Fish jumping into you boat is a problem? Isn't that catching lunch without even trying?
@@zapfanzapfan the carp taste bad tho
@@zapfanzapfan carp is gross plus i dont think a concussion or whiplash is worth a fish dinner
@@ThimbleFox350 Really? I haven't eaten any. Does it have any caviar?
@@zapfanzapfan Nah, just Grey Poupon and ham.
I love the bit about having to shut down the barrier. "We're trying to protect the ecosystem, so we dumped a ton of toxins into this river."
they know more than you
The scary part is that killing everything in the canal, while bad, has far less ecological impact then carp getting into the Great Lakes system would.
Also, "We really messed up the ecosystem and really, really want to fix it, but not actually enough to affect profits by using the easiest, most effective, and ecologically sound means."
@@joelsmith3473 Which would be what exactly?
@@amshermansen Closing the canal, they mentioned that in the video
its amazing how such a big project with tens of millions invested could be ruined by a single person if someone decides to throw a few carp in the river upstream
That's what happened in NZ, we had one rogue 'eco terrorist' who bred and released exotic fish all around the north island before he was caught. Quite interesting, but the damage he caused was massive
How could this portion of the slave system be ruined?
No, it would happen in our lifetime. They have no predators and release hundreds of eggs at a time, so there's noting killing them. That's what happened with the zebra mussels.
The opening info talked about how floods can potentially send them everywhere. So what happens if the electrical barrier fails due to a massive flood?
"They can weigh more than 30 kilos, and they are easily startled."
Story of my life.
This reminds me a little of the buffelgrass problem facing Arizona these days. It was bought from Africa to the area in the 1970s as a drought resistant grass for cattle and for erosion control. This grass seemed ideally suited to the area as it can go for 8 months in searing heat and rebound with a little water. Fire can't destroy it as buffelgrass roots rebound quickly in charred soil. No one considered how its introduction might effect other plants and animals.
Because part of buffelgrass' annual process is to become dormant and dry out, the areas where it is introduced become tinderboxes. When fires occur, it kills the other plants in animals in the area, leaving the buffelgrass to grow even stronger the following year. Fast forward to today and buffelgrass is everywhere. Its introduction is now effecting Arizona's iconic saguaro cactus. The only way to get rid of buffelgrass is to pull it up by its roots and volunteers have been going into the desert and doing just that for decades. This has slowed the spread but unfortunately there's no way to eradicate it completely.
We have kudzu in the South. Originally brought in for erosion control. You can see it literally completely covering whole stretched of woodlands.
Lion fish in the Gulf of Mexico and the Caribbean Sea. Pythons in Florida. Both Asian species, that got brought over as pets, and escaped, and exploded, in recent years.
It's simple! Just introduce another species that eats the buffelgrass! Don't look into _that_ species' environment impact. If the next thing becomes a problem, we'll just introduce another to take care of it. Easy! No consequences whatsoever.

I truly hope the s works I live on the great lakes here in Canada and if they get through it will ruin us. Thanks for this report.
Just to help out with English to English translation: Likes = Lakes. So live a lake up above.
Hi Tom Scott, We have something similar but different in the Netherlands. There is a sluise or lock between a saltwater and freshwater that is supposed to stay separated. They originally pumped the salt water out of the bottom and pumped freshwater back in before opening the lock, but now they use bubble walls too keep the water separated. It looks really cool, and can be another interesting place video.
@erik zaal; Well, I guess it would keep water seperated, but not impenetrable, right?...
Unforutnately those aren't perfect (of course) either; the freshwaters are getting more and more saline which is a huge problem for many species. I wonder what they will do to prevent this from getting out of hand!
Fish retreat from bubble curtains
Loved listening to the engineer who works at the fish barrier, he really knows his stuff and explained it well.
learned more from tom than i did from 12 years in school
Well done Scott. Good info without any crap music.
Another Tom Scott production on a subject I did not know existed, that I am delighted to have spent 10 minutes of my life - thanks Tom
I be making entertaining videos as well🤠
Yes, time spent watching Tom's videos never go to waste.
I did some school projects (for my major in college) on this and other invasive species. It’s very interesting, but there are still some evidence of asian carp in the lakes already, mainly due to temporary barrier outages
That makes me sad. That barrier is not enough, we need much more.
@@runstarhomer2754 yes. Close it
They have been in the great lakes for years. Here on the Canadian side its against the law to release an asian carp if you catch one, You have to eliminate it. The damage is done, Only getting worse. Its what happens when you play mother nature and make rivers and canals joining 2 separate ecosystems.
@Mark Michon that would take insane expenses and it'll probably not work anyway. The population could restart from a couple fish. That is not possible to account for. No matter your resources. Even if you get the entire chinese rural population to do it.
@Mark Michon I'm just saying, best efficient way to do it is introduce a predator. Engineer an ecosystem. Not exterminate life needlessly
And they said magicarp was harmless
wow human intervention who would imagine that
I work on a river boat and pass through there on occasion pushing barges. When we pass through, we have to run a steel wire from our boat to the barge that we're faced up to because there is a layer of rubber between the boat and the barges. This is to provide continuity of the electricity. When we pass through the arch that is behind Scott in several of the shots, you can see the electricity arcing between the boat and the arch.
What happens if you don’t provide continuity of the electricity?
@@abnormal_asian5320 probably fish can get through
@@abnormal_asian5320 A potential can build between the two structures. You, as a human, have a chance to be the electrical conductor in that scenario. Good luck!
@@PiperDougherty the WIRE is the conductor-it connects the steel of the boat to the steel of the barges. It is a braided cable over an inch in diameter. Also, we stay inside the vessel during passage through the electrified area.
The purpose of bonding the vessel to the barges(to my understanding) is to prevent a pocket between the bow of my vessel and the stern of the barges that would allow the fish to pass through the zone unscathed.
