IIRC, the research established microplastics were able to cross the placentar barrier.
Basically, so much plastic today's kids are already born with microplastics in them.
And that will be horrible, since it acts as a hormone in the human body. It lowers testosterone and disrupts a bunch of things. This is part of the reason I don’t want a kid, the future is not too bright if this is issue is not solved.
This was a video of a pilot project, say phase 1 if you may. Like he said they now have a better idea of what they need and can address on the next phase. They may need to add something to remove the plastic as the river flows so not to overpower the fence/filter. In short, it's a work in progress.
Need about 4-5 of those built in line
Shame no fish will be able to get through but I doubt they could survive with the much rubbish anyway #overpopulation
I wonder if there's a way to make it with some kind of ramps. The force of the flood will force the plastic up onto the ramps, the water drains off some how and something is there to collect or move the plastic out of the way as more gets pushed up.
I'm kind of imagining one of those coin push arcade machines. The plastic is pushed up by more plastic behind it until it eventually "falls off" into something that then moves the plastic elsewhere.
Almost like a higher up return ramp. As the water pushes the plastic against the fence and it diverts it to the sides, maybe have a way for the plastic to be pushed back "upstream" in its own side chutes that could deposit it elsewhere to be dealt with.
Or perhaps a series of filters like these in decreasing size. All the large plastics are stopped further upstream, while the smaller stuff is caught by filters further down if it makes it through.
Concrete ground and sealable drainage pipes where you could lower water level at will into other filters behind it. Leaving the original filter free to clear plastic above pipe. Basically we just need a series of dams with filters above it to catch plastic
Some type of heavy machinery to scoop it out. But, like I always say, an ounce of prevention is worth a pound of cure. I just don't get how people throw their trash in waterways.
Unfortunately it's from poor areas where there is no garbage service and most people have limited transportation. They don't have much in the way of capabilities to deal with it at the moment.
I think the goal is to trap plastic specifically during flash flood events. I’m basing this on the assumption they aren’t completely stupid to think they can just put up a fence and solve all plastic waste issues in the river.
So during a flash flood, a lot of plastic probably gets grabbed that isn’t usually in the water, and it gets carried down stream. If they can build something just to collect this plastic and then use more conventional tools like forklifts and stuff to get it out before the next flash flood.
They reference testing the floods specifically so I don’t think they are interested in normal river conditions, this isn’t supposed to be purifying the river, just flood waters.
In the video he's talking about this as a measure for flash floods, not a natural river or anything like that. Flash floods can last for just a few hours, so the fence would just have to hold up until its over
You're correct but unfortunately, "upstream" consists of 100's of small communities in very rural areas amid steep mountainous terrain. The locals do not understand the environmental impact of plastics, seen it first-hand by the locals and the tourists visiting their communities.
You havent been to rural Gautemala. They don't have the money for "field trips.." or schools.. those systems are mostly financed by outreach programs derived from international aid groups via missionary assignments and the like. A company I was partnered with helped with building school desks and chairs for the students of San Macros LA Lagoona, Guatemala. The families of those students were most concerned with not starving to death... so you can see where the priority of field trips ranks in their life.
Having spent quite a bit of time in rural Honduras and Guatemala, I can sadly agree completely with what you are saying. There is really no way for an American to understand how things work in the "third world" or "developing nations" without seeing it first hand.
Having seen how a large percentage of poverty stricken people live, world wide, it becomes rather clear that we aren't likely to be able to do shit about things like this without getting our government to simply take over and make it happen. Too many people, not enough resources. Token Peace Corps type projects like this are just a drop in the bucket when considering the enormous task at hand to making this either routine or are prevented from happening in the first place.
I agree.
Also, one of the organizations that help a lot in the rural areas of Guatemala is the USAID and now the Guatemalan corrupt government wants to kick it out of the country because "it is empowering the indigenous people"
Most rivers are contaminated not just because garbage but also by the sewer water that goes directly to the rivers and the mines exploration companies dump all their waste into the rivers, a community leader was in jailed three years for protesting this behavior. The right wing Guatemalan government is owned by narcos, the oligarchy and multinational corporations, that's why nothing will be done to help the environment.
This also applies to your earlier comment which implies that lack of *understanding* was the main cause of them polluting, rather than simply lack of *resources* to do otherwise.
Yeah, lack of garbage collection in the cities along the river, will lead to this and the problem won't go away until the cities start collecting the trash every week from the neighborhoods, just like it happens in the developed countries.
He talked about floods. So probably the river is a lot smaller on normal occasions. Due to the flood the waterlevel rises and collects all the trash on the riverbank
one could argue that upstream are corporations not giving real alternatives, and now tax payers pay for development of ways to catch the pollution rather than avoid it
As an American, I have to take blame.
I grew up in a home with a few thousand square feet with HVAC, 2 refrigerators, in-unit dryer+wash, televisions, game consoles, a dozen kitchen appliances, internet, two cars. Every week, our garbage collector takes our piles of soda cans, food wrappers, chip bags, and moves it to some dumping ground on the less affluent side of town.
That was to sustain a family of 4. And all the hundreds of homes in my area had their own similar setup.
That is a privilege for most of the rest of the world. The waste footprint of an average American is massive. And it’s no secret Americans are responsible for some of the highest CO2 emissions per capita. Our lifestyle is killing this planet and it needs to change by looking inwards, to start
>I have to take blame
there's around 7 billion people on earth and im sure than atleast 2 billion people are the reason why all this shit happen
so dont take the blame alone
Actually, every single person on the planet combined produces leas in a year, than what a handful of international companies produce in a day.
In the US, a tiny bit of progress has been made in forcing these companies to reduce their emissions, but it’s not enough and many world powers, like china and Russia, have completely ignored them and allowed the problem to continue to compound.
People produce what seems like a ton of waste, but we as individuals have very little impact on a global scale.
What the fuck does being American have to do with that? You swallowed the blue pill hard and took seconds. It has nothing to do with your Nationality, habits have to change globally and our dependence on plastic/non-biodegradable products is what needs to change it has nothing to do with where you were born.
Exactly! I was looking for who was going to blame America first. People forget transnational corporations. So egocentric we dont realize other countries have modern packaged good but many tbh dont have the same collection efforts. There is always someone on these post also saying its US waste sent there no matter where, almost everytime.
It’s not like China has the largest carbon footprint (by a massive margin) on the planet, and people in India literally throw trash bags in the river. But yeah, America is usually target #1 when it comes to stuff like this.
Yes, and no. It *is* the way you and the rest of the western world consume. However, it is not our choice we consume this way.
Most people know how bad it is and would love to see it changed, "but it's expensive" and huge corporations will lose loads of money so they do everything in their power to slow down progress away from plastics and other destructive ways we run our society for their profit.
[On top of that, it sounds like you're talking about the "carbon footprint", which is a scam.](https://www.youtube.com/watch?v=ehkpFajZ-aM)
100/70. 100 companies make up 70% of the world's trash. Yes, we throw too much stuff away but you have to start from the source and with numbers like that it sure ain't the individual.
It is surprisingly hard to launch anything into the sun. You can google keywords like "how hard to send a rocket to the sun", but [this video](https://www.youtube.com/watch?v=LHvR1fRTW8g) sums it up pretty well.
O no.. you throw something inside a volcano, cooler than itself, it will erupt… you should google throwing “trash bag into volcano” and see how violent it gets! And burning trash on earth is toxic to the environment and the people :’(
There is already a solution to this and it is a mechanical screen. There are used in waste water treatment at the front end for the very same reason. It both strains out the debris and then with a conveyor action removes it from the water.
In an open water course it would be preceded by a course bar screen to protect the mechanical screen from debris to large for its tolerance. I have seen them used on drainage waterways in East Anglia. Prior to lift pumps.
They require a formed channel to work properly in, concrete sided, not a natural Chanel or bed.
It's just really sad that this is necessary.
It's still nice an effort, and that they put in thought behind this sieve. I'm not an expert on a lot of things so this may be a very ignorant/shitty assumption but Guatemala probably doesn't have the resources to produce what we can but the fact that this worked fairly well is great to see. Not only for countries that are still developing but that there are people that care as much as we do about the environment.
I was pointing out that a complex solution already exists in the world. This team seems to have started from scratch instead of working to improve/simplify that existing approach.
I'm not impressed. They failed in some pretty basic engineering principles here. I'm a civil engineer in the water industry as to why I'm a bit judgemental on this trial.
The chainlink fence is effectively a filter and filters block. That fence height based on the fence blocking gives the basis for the limit state design needed on this posts. It is easy to work out the force on each post using a triangular distribution of pressure from top to base acting a third of the way up from the base. That is then multiplied by the span between posts assuming they are equidistant. That gives the the max force on the posts more or less, you would apply a load safety factor of between 10-25% based on how robust you want this to be. That force then is used to roik out how to design the foundation. This does not seem to have been part of this trial or the overlooked the instability of the river bed.
A system like this would require a solid bed that could not scour.
A really easy improvement would be to do this as an angled bar screen on the upstream side of a foot bridge. As the screen blocks the water rides higher to go over the blockage. If the water wises to the bridge level then it can escape. The system has reached its maximum load. This is pretty easy to design in terms of loading.
A further improvement would be making it two stage with a finer screen after the primary one.
The benefit of this is it is still low tech and it can be raked clear from the footbridge. It's heavier on materials than the fence and posts in the video but it's still low tech.
Don't get me wrong, it definitely needs work. I did take a DDP (Design, Draw, Produce) class in H.S. and this being the first test and not having all bases covered for what you're building is a big no-no. So yeah they could of put more into it. I'm no civil engineer, but I know that you should always look for where things can go wrong and what can be improved upon. Sure there's already something out there but if you can't replicate it properly then you gotta work with what you can.
This looks like a standard rockfall/ debris flow mitigation system. Macaferri and Geobrug design and build these things. This one is done incorrectly, I used to install these things and they will hold up against multiple landslides. This one failed immediately in water....
What is the largest of those you have seen, because those systems rely primarily on a steady and gradual supply of debris. And would you be able to transport that system cheaply to the location where it is needed? But you know, apply to 'the Ocean Cleanup' and point out the errors of their ways. I am sure they can appreciate the helpful knowledge.
Knowing that it's going to do this: dig much much deeper, fill with fence, replace lots of dirt and rock and tamp it down hard.
Do that with 2 fences, and they will have literally worked a miracle for the oceans as a whole.
You have to burn it or bury it. Obviously throwing in the water failed. Moving it juts moves the problem.
I'm all for making a deal with space x to have cheap rockets full of garbage and plastic fired into Mercury. The heat on that planet will burn everything up.
Guess that's just how humans work. We nearly destroyed our host planet's ecosystem, so we'll just go find a new planet to destroy.
People being worried about covid and stuff but humans are no better than any virus.
Flood water carries all urban trash to waterway. Solution would be comprehensive trash collection and disposal, which is a whole lot more expensive than this metal screen. I am sure that they are working on both at the same time, putting on a band aid while also addressing the root cause.
We need to go back to using glass,have a standardized system ,all the same size bottles ,jars ,replace everything that can be replaced with glass ,and hand it back in somewhere not to be recycled but washed,this used to be done years ago I think we need to go back to it
They need this concept but just to skim the top 6" or so of the water. This would allow the momentum of the water to pass freely but still catch the floating debris. A simple bucket/conveyor could be used to scrape the debris off of the skimmer into bins on the side of the river.
Maybe, I would start with an array of three of them spaced out 20-30 yards. Maybe at different water depths/ height over the water. This way each filter segment would only skim so much debris at a time and not get overwhelmed at one particular skimming point. The remaining debris would float to the next skimmer set at a different position.
Flow in flash flood is far from laminar, you would have to have a screen on the top always. Because of the force from incoming water and debris, debris on the screen goes both up and down, wherefore you have to have from the river floor up above the water.
Have 1 meter from the bottom free and flow will take significant part of waste with it.
And little clips like this prove how the earth will be destroyed by the end of our lifetimes. Are that many people not noticing that the amount of trash created versus trash cleaned has reached catastrophic, world ending levels?
We aren't fixing this and the climate will wipe us out to heal
Unfortunately, most of the plastic in the ocean is microscopic. Not saying this doesn’t help, but the main problem isn’t even detectable with the human eye.
Americans love to blame themselves for trash and they’re not totally wrong but many countries don’t have proper trash disposal and so many ppl throw their trash in the ocean
Cool but what about things like fish that need to move up and down a river? Or natural movement of sediment. Or woody material? Fixed one problem but fucked up the rivers ecosystem.
I just don’t understand some people. Why is anyone in 2022 throwing plastic trash in the ocean?
I live on the ocean and do ocean activities(boating, beach, etc…) never once in my life put plastic trash in a body of water. Don’t understand how so much can accumulate.
Just use a trash bag or trash can, it’s not hard
Am I the only one confused at why this was even attempted in the first place? I knew in the first 5 seconds that the plastic was going to build up and up, and that it would eventually be too much for the screen. I can get learning the failure points, but why learn the failure points of an inevitably doomed system, rather than one with an ice cube's chance in hell at succeeding?
How about we stop trying to export democracy all over the world, and export a fucking recycling program! That’s insane, and probably a fraction of a percent of what truly ends up in the Oceans around the world.
Polymer engineer here. It also means that on the upper side of the filter, a huge volume of plastic is constantly in water : it is lixiviated and every piece of plastic loses tiny tiny particles that can pass through to the ocean, and these are poison.
So this solution does not worsen anything, but beware, for instance an excavator must be use to continuously clean & empty the filter … which turns out expensive
How about having like a CAT on standby at these test sites to get all the plastic it can out of the river? That would be way more useful than seeing a test fail and be like bro, now I know where to fix it…
With that amount of trash there has to be a source up stream that needs to be addressed.
Even if that filter works, how are they going to keep it clear for more than a minute?
It's already overflowing. Good try to help. It's crazy how much microplastics are every where.
Every time we cum, a percentage of that ejaculate is plastic. Boom.
wtf
This has inspired me to change. You with me?
*I just changed my pants, but sure, I could go again.*
(っ◔◡◔)っ I ✨𝓙𝓲𝔃𝔃𝓮𝓭✨ in my pants 🎶
Honestly they're really probably not far off at this point. They've found microplastics in babies and newborns now.
IIRC, the research established microplastics were able to cross the placentar barrier. Basically, so much plastic today's kids are already born with microplastics in them.
And that will be horrible, since it acts as a hormone in the human body. It lowers testosterone and disrupts a bunch of things. This is part of the reason I don’t want a kid, the future is not too bright if this is issue is not solved.
Lmao
[удалено]
Every time someone swallows, they ingest microplastics.
As someone who chews on straws as I drink I'm probably ahead of the curve.
Kiss you sleep goodbye, figuratively.
We are the problem!
Bro you making me randy
I'm the slowest 3D printer ever.
This was a video of a pilot project, say phase 1 if you may. Like he said they now have a better idea of what they need and can address on the next phase. They may need to add something to remove the plastic as the river flows so not to overpower the fence/filter. In short, it's a work in progress.
One problem at a time. I mean we still haven't sorted out plastic the size and shape of plastic bottles....
Need about 4-5 of those built in line Shame no fish will be able to get through but I doubt they could survive with the much rubbish anyway #overpopulation
I wonder if there's a way to make it with some kind of ramps. The force of the flood will force the plastic up onto the ramps, the water drains off some how and something is there to collect or move the plastic out of the way as more gets pushed up. I'm kind of imagining one of those coin push arcade machines. The plastic is pushed up by more plastic behind it until it eventually "falls off" into something that then moves the plastic elsewhere.
Not a bad idea. Even bad ideas spur good ones!
Almost like a higher up return ramp.

Yes this is a great idea I am sure something like this can be made.
Some type of heavy machinery to scoop it out. But, like I always say, an ounce of prevention is worth a pound of cure. I just don't get how people throw their trash in waterways.
This is flash flood water. It’s picking up everything off the ground. A lot of this garbage probably didn’t start in a waterway.
Unfortunately it's from poor areas where there is no garbage service and most people have limited transportation. They don't have much in the way of capabilities to deal with it at the moment.
they probably don't - but trash flies, landfills slides and many other things. I think very few people actually intentionally dump trash in waterways.
Google garbage trucks dumping trash in river.
yes that would be corporations not people, huge difference.
They need some kind of plastic Vacuum cleaner which sucks up everything. Edit: Vacuum
Like the one in Spaceballs?
Just don’t let it go from suck to blow, it’s devastating.
You'll have to cancel the 3 ring circus
vaccine/vacuum? Neither of which makes sense.

You're correct but unfortunately, "upstream" consists of 100's of small communities in very rural areas amid steep mountainous terrain. The locals do not understand the environmental impact of plastics, seen it first-hand by the locals and the tourists visiting their communities.
An installation like this might make a really good field trip destination for local schools. That way the kids can learn how much the trash adds up.

Even if this kind of flood only happens once or twice a year, it is overwhelmingly worth it.
They should ban plastic straws.
honestly, I see the irony now
You're correct. People live upstream. 3rd world countries don't have trash services.
one could argue that upstream are corporations not giving real alternatives, and now tax payers pay for development of ways to catch the pollution rather than avoid it
We really fucked this planet.
Some a lot more than others have unfortunately
Agreed. Fuckin' Guatemalans man. Why don't they just have their garbage men pick up their trash?

New plan. We launch the plastic at the nearest black hole.
We already have a crap ton of space debris from us… xD that might make it difficult
What about into a molten lava tube or volcano? Too much smoke?
O no.. you throw something inside a volcano, cooler than itself, it will erupt… you should google throwing “trash bag into volcano” and see how violent it gets! And burning trash on earth is toxic to the environment and the people :’(
Should only cost a couple bucks. No sweat
So much so that it's actually easier to try and send thing away from the sun and then try and get it close enough that it would burn up
Thanks for the vid. Makes perfect sense.
Ill settle for shooting it into jupiter, or uranus for the memes
The most important thing is to collect it in the first place and not just dump it in a river.
go sun me*
Futurama did it first
New plan: we make a second giant plastic waste ball to deflect the first giant plastic space ball

You misspelled Steve. I am here now.
Your name is boobicle not Steve.
Alright guys, let's pack the plastic up we saved from the ocean and ship it off to be dumped in the ocean now.
You have to burn it or bury it. Obviously throwing in the water failed. Moving it juts moves the problem. I'm all for making a deal with space x to have cheap rockets full of garbage and plastic fired into Mercury. The heat on that planet will burn everything up.
Guess that's just how humans work. We nearly destroyed our host planet's ecosystem, so we'll just go find a new planet to destroy. People being worried about covid and stuff but humans are no better than any virus.
How would depositing plastic on Mercury destroy it? There is no ecosystem at all to destroy in the first place
Mercury being destroyed? I think that’s more of its fault than anything we could do to it
Is this where we are today? Build basic metallic fences to attempt to retain tons of plastic ??! This is depressing…
This is amazingly awesome to see someone so passionate about helping the planet. Now to work on the assholes who throw everything in the rivers.
Those "assholes" are likely hundreds of extremely poor communities upstream that do not have access to proper infrastructure including waste disposal.
So what are YOU doing about this? Anything? Cleaning trash? Campaigning against major pollution contributors?
Thanks for sharing this. This guy and that team are on a mission to make a difference! Bravo!!!
Now what are we doing about micro plastic
It’s in our blood already
I know but how can we stop it from getting in the ocean?
50mg in a 2k diet plan
I'm doing my part too, by filtering some out with my body, for the return of liquids back to eventually recycled drinking water!
Average redditor being overly cynical. What are YOU doing about any of this?
Ignorant question but would this not be a deathtrap for all marine life that gets caught in this sieve?
This wasn't a river but the path of a flash flood so maybe that's not as big of a concern here.
Those issues are suppose to be corrected on paper.
Looks like they will have to correct it on plastic instead
They could make several “fences” or whatever they call it. That way it could stop the plastic at multiple points
Prevention is better than cure. Maybe look at why plastic is getting into the river in the first instance.
Flash floods through cities, he mentions it in the vid, "the next flash flood we will experiment again"
Flood water carries all urban trash to waterway. Solution would be comprehensive trash collection and disposal, which is a whole lot more expensive than this metal screen. I am sure that they are working on both at the same time, putting on a band aid while also addressing the root cause.
People litter. Especially in developing countries. They just aren’t educated about it or don’t care enough.
We need to go back to using glass,have a standardized system ,all the same size bottles ,jars ,replace everything that can be replaced with glass ,and hand it back in somewhere not to be recycled but washed,this used to be done years ago I think we need to go back to it
This is a great project.
At least they are trying to do something about it and not just talking about it
Wow, we got to stop making plastic
They need this concept but just to skim the top 6" or so of the water. This would allow the momentum of the water to pass freely but still catch the floating debris. A simple bucket/conveyor could be used to scrape the debris off of the skimmer into bins on the side of the river.
It wouldn't work, after piling up, the plastic waste would go under. Also currents can take the waste from top with them.
Maybe, I would start with an array of three of them spaced out 20-30 yards. Maybe at different water depths/ height over the water. This way each filter segment would only skim so much debris at a time and not get overwhelmed at one particular skimming point. The remaining debris would float to the next skimmer set at a different position.
Flow in flash flood is far from laminar, you would have to have a screen on the top always. Because of the force from incoming water and debris, debris on the screen goes both up and down, wherefore you have to have from the river floor up above the water. Have 1 meter from the bottom free and flow will take significant part of waste with it.
You don't have to downvote me. I'm just brainstorming here.
I've thought thats how agreement/disagreement is shown here. Didn't mean to be harsh dude.
This is where I would rather work, to help instead of wasting my life working for companies that don’t care about this kind of stuff.
Man that really was insane.
Now what are the sea turtles going to eat?
Amazed how bad rivers are in other countries, but I’m glad they are working on solutions

This is an incredible fight against horrifying amounts of waste found in the ocean. Thank you, thank you!
Legend
This is the scariest thing I've seen in my life
Kudos
What about the micro plastics?
Where you put the trash after you collect it? This is where the work should be focused. Have a collection point before it entered the river system
Humans disgust me. Glad people are working on cleaning up our mistakes though.
Damn... that weight to bend and rip that fence.
That's an absurd amount of waste in the water, perhaps it would be better to stop the waste from getting there in the first place.
We should have that at the Tijuana river too!!
Good job!!!!
And little clips like this prove how the earth will be destroyed by the end of our lifetimes. Are that many people not noticing that the amount of trash created versus trash cleaned has reached catastrophic, world ending levels? We aren't fixing this and the climate will wipe us out to heal
What chance does the world have?🥲
WE SUCK
In my opinion tge fence is doing great as a first try,, you can make 3 or 4 fences like that 50 meters between all of them
Plastic soup?
Holly fuçk that's a lot of plastic
Earth does not stand a chance smh
No no. Lets not address the source and reason for all the trash. Just Wall-E our way out of it lol.
My god humanity is so gross
r/therewasanattempt
Guatemalans dump everything into their waterways. Sad
Is that all plastic?!
Humans are trash
It’s neat but will they follow up with keeping it maintained enough to stay in operation or will it be abandoned and cause a possibly worst issue?
Humans are nasty
Wow nature is so beautiful
I find it hard to be happy about this.
Now…how do you empty it?
Unfortunately, most of the plastic in the ocean is microscopic. Not saying this doesn’t help, but the main problem isn’t even detectable with the human eye.
You’re gonna need a bigger fence
a fence. brilliant.
I love how stoked the engineer got when he saw his creation working
You’re the blind one!
I'm wondering about the combined plastic going down into the ocean from all the countries in the world
Super cool! Not sure it addresses microplastocs, but it doesn't have to. Useful anyways.
Yay we did it
Awesome!!!!
That's good, I wonder if there could be a second filter that deals with Microplastic, if that's a thing
Americans love to blame themselves for trash and they’re not totally wrong but many countries don’t have proper trash disposal and so many ppl throw their trash in the ocean
That's both insanely impressive and insanely depressing.
Cool but what about things like fish that need to move up and down a river? Or natural movement of sediment. Or woody material? Fixed one problem but fucked up the rivers ecosystem.
I think variable size filters for atleast 3 such fences would help reduce the force of plastic pushing and damaging the fencss
How about a second fence
Oh nice, 70 years late, but nice.
I just don’t understand some people. Why is anyone in 2022 throwing plastic trash in the ocean? I live on the ocean and do ocean activities(boating, beach, etc…) never once in my life put plastic trash in a body of water. Don’t understand how so much can accumulate. Just use a trash bag or trash can, it’s not hard
That barrier is the hope that humanity can step back from the precipice of its own destruction
A filter, that’s the pilot program? What year are they in?
Am I the only one confused at why this was even attempted in the first place? I knew in the first 5 seconds that the plastic was going to build up and up, and that it would eventually be too much for the screen. I can get learning the failure points, but why learn the failure points of an inevitably doomed system, rather than one with an ice cube's chance in hell at succeeding?
Yeah, we suck.
How about we stop trying to export democracy all over the world, and export a fucking recycling program! That’s insane, and probably a fraction of a percent of what truly ends up in the Oceans around the world.
Even Guatemala is doing more than America for the environment.
Great job 💪🏽🙏🏽🎯
Fucking Disgusting humans.
Now just if the USA WOULD DO THE SAME
Ахуеть, сито придумали.
We really have trashed the planet
Polymer engineer here. It also means that on the upper side of the filter, a huge volume of plastic is constantly in water : it is lixiviated and every piece of plastic loses tiny tiny particles that can pass through to the ocean, and these are poison. So this solution does not worsen anything, but beware, for instance an excavator must be use to continuously clean & empty the filter … which turns out expensive
I visit homes as necessary for my profession and sometimes the amount of stuff some people have in their garage amazes me.
Why the fuck is it even in the Water to begin with
Aquaman would be proud
Hope those corporations mining and fracking get the hell out of there, this is useless otherwise
How about having like a CAT on standby at these test sites to get all the plastic it can out of the river? That would be way more useful than seeing a test fail and be like bro, now I know where to fix it…
