There is a easy solution. Turn 80% of the sea in protected Areas where all extracting of natural resources is banned and the ban is enforced. Protected Areas are selected by habitat, spawning ground and travel routes of fishes.

[@em-yz6rl]

This would cause the price of fish to rise and end up creating a huge black market. But if we spend enough fighting that black market, eventually fish will cost so much that the average person will stop buying it. Over time this would change cultural attitudes towards fish as being a luxury item, and keep consumption at relatively low levels, until new fish-producing technologies are created or the ocean recovers and fish become cheap again. Or at least, that's how it would play out in countries where corruption isn't very common. We might instead end up buying cheap fish exported from China where they're paying off the regulators to fish in protected areas.

[@MasterRoshi69]

@@em-yz6rl You're pretty much right on the money on this. Most regulations turn into black markets. Especially true about the China part.

[@nunikoh]

Can you please talk more about the impact of mass fishing in the ocean and the impact of it on marine life?

[@thecommabandit]

Very disappointing to see SciShow talk about blockchain technology like this. Crypto evangelists love to talk about how blockchains are unhackable but ignore the fact that almost all fraud happens because an authorised user deliberately inputs false information into the system, i.e. a fishing boat lying about their catch. This is a problem that blockchains not only don't solve but also can't fix once it's been discovered, since the false data is immutably recorded on the ledger. Other than that, a great video.

[@spambot7110]

Not to mention their brief mention of it being "energy intensive" is uh bit of an understatement. Immutability isn't necessarily a problem, you just add a type of log entry that represents a correction to a previous entry. The original entry remains untouched, and then you not only fix your data, but preserve a record of the original error and when it was corrected, which could be useful for accountability purposes. That being said, there's plenty of ways to do immutable ledgers that don't boil the planet (if you've ever used git that's a perfect example), so this is in no way a defense of blockchain technology.

[@jfolz]

I like that most of comments are "just don't eat fish". When it's something that you don't care about the solution is really obvious. I actually found some "fish fingers" made from scorzonera (black salsify) that I like better than ones made from actual fish. They also make way less of a mess when you fry them.

[@huldu]

You can't blame people for living in their protective bubbles. A huge part of the human population DEPEND on fish as a food source.

I thought the fish scales would function as the QR code, though that would only work if you buy whole fosh and if the scales are unique enough on each fish.

[@jamesconnop4029]

Nice idea - but fish lose and regenerate scales all the time, so it's hard to find 2 scales on the same fish that tell the same story. Also, since all marketable fish stocks are social (i.e. harvestable) animals by definition, you'd have a whole crapload of fish in the same cohort with identical scale signatures.

The word “sustainable” has become so green washed, corporatized. True ethical choices are almost made entirely individually on a small scale. The ocean is so vast- accountability is an almost impossible feat. But if we have any leverage against profit driven companies into playing nice, we should use it to prevent tragedy of the commons. I hear most pollution in the ocean is fishing related. Maybe we have some duty to clean up while we’re scooping fish into dry land 🌟 🎣

[@Jack-tk3ub]

You are right, nost of the plastic in the ocean is from discarded fishing nets Ironic that we focus our attention on plastic straws and the like, which make up a tiny % of plastic in the ocean, when simply not eating fish would have a much bigger effect!

As a Bostonian, I'd eat seafood multiple times a week if I weren't also a vegetarian.

[@ivoryowl]

"I don't know many americans at least that eat fish on a regular basis." And there's your problem. The US is probably one of the worst countries to based your information upon because americans in general tend to have really lousy diets and aren't as big on fish as they are on meat, especially pork and red meat. Here in my household we eat fish about 2 times a week. Salmon, tuna, cod, european hake, european seabass, horse mackerel, squid, common sole, grouper and red snapper are the most common fishes we eat (other households may have more or less variety). We live in western europe and our diet is mostly mediterranean. My country is one of the world's biggest consumers of cod (imported from Norway), it's like a national staple here.

Chris, from 2:20 he starts to explain about over-fishing and how this can be mitigated. First, we need a better way of collecting data on fish numbers so quotas can be established to keep the population sustainable. Second, we need cameras on boats to keep them honest. AI technology can be used for both purposes for both data collection and recording all fish brought on board using the cameras. The hardest part is getting the fisheries to agree to the cameras. They are highly resistant to allowing that every where a government tries to improve the industry.

That's not going to happen since so many people across the world depend on fish in one way or another. I agree completely with you fishing is not sustainable today but then again, many things we depend on aren't. We humans become more and more every day - not less. Things are only going to escalate even further and talking about it won't help. It'll reach a point where it's gone too far and by then it's too late.

C'mon sci show, we all know fishing can never be sustainable... especially in farmed situations. The use of anti-biotics also makes fisheries dangerous to humans due to anti-biotic resistance; much in the same way that land based farming does. The only way we help keep fish "stocks" high is by ensuring that fish aren't seen as "Stock" at all; the incentive to fish on such a large scale needs to be removed all together. Much like the war on drugs; the war on drugs can't win because the incentive is too high to cheat the system. Fishing illegally or over fishing to increase profits is another one of these examples.

It's pretty sad that many humans still want to believe changing a bit of technology would help nature to recover. History tells us that this is just not going to happen. There is one extremely simple and free alternative to this that will definitely help: less fishing

[@bobthegoat7090]

Couldn't we just use proof of stake instead of proof of work with the fish blockchain? Then we wouldn't need to use so much computational power.

[@spambot7110]

proof of stake in what? make an entire currency just to serve as a basis for a fish database? even if this made sense and were implemented, one or two rich countries invests in the majority of the tokens or whatever, and then we're back to more or less a centralized database, but way less efficient. What you could do is set up a treaty where each member country gets to run a node in a global database, that maintains distributed consensus through a voting protocol, preventing any one or few nations from cheating without being caught. And you could even maintain an immutable log by including the hash of the previous entry in each entry, preventing anyone from retroactively modifying a record without it being immediately obvious to all other parties. But cryptobros would immediately disavow it because even though that looks and sounds a lot like a blockchain, it uses a bit of bureaucracy to regulate who controls the nodes instead of burning tons of coal and/or ever sketchier financial instruments to hack together a free market solution. realistically, governments being governments, it would be a hodge podge of crappy websites with big tables of numbers and CSV files, with agents periodically doing painful excel stuff to audit other countries' data against their own. which would still be orders of magnitude more efficient than blockchain and just as effective

[@bobthegoat7090]

@@spambot7110 Unfortunately we live in a very capitalistic world and so yes I think an incentive is needed, for normal people to keep the blockchain. Also there is delegated proof of stake where you would lose your power as soon as you act against the community. Plus we live in the real world where if you hacked the fish blockchain there would be extreme consequences

[@spambot7110]

@@bobthegoat7090 why would you want "normal people" to run nodes? I'm talking about governments running essentially a private, permissioned blockchain amongst themselves. governments don't have to act on a profit incentive, they can act on the public good (regular people are capable of this too btw! think of folding@home, BitTorrent, and Tor, or more broadly, people volunteering, giving donations, helping out neighbors, etc).

look as much as block chains promised de-centralization, it absolutely doesn't do that, at the end of the day there needs to be an organization or group of organizations managing the trasactions. i mean just look at crypto, majority of people don't actually have personal crypto wallet but instead have one hosted on a few select slightly sketchy websites. a block chain ledger would be no more effective than a normal database ledger. so of course i'm going to roll my damn eyes at it.

Play by the rules. Well that's where your first problem is the second is sustainable consumerism.

[@MoritzvonSchweinitz]

I don't think Blockchains are inherently energy intensive. After all, they are simply a chain of blocks where the las block contains a cryptographic hash of the previous one, recursively. So, as long as the Blockchain ()or even just the hashes) is published openly, it's impossible to manipulate. The energy intensive part is part of the decentralized system, which isn't really an issue in the case, because the UN or whoever would easily host this Blockchain, which could be mirrored by anyone else, with guaranteed data integrity

[@spambot7110]

You are technically correct, but that's not what anyone thinks when they hear the word "blockchain", that word's been poisoned by the cryptocurrency community. IMO a science show like this referring to "blockchain" is irresponsible, since it gives legitimacy to the inevitable wave of Etherium guys claiming they have a solution. It's a good term, but i think for the next few decades we'll have to call it like a "hash-based immutable log" or something to avoid getting overrun by crypto bros.

[@sanjuansteve]

Especially in times of pandemics and climate change, it’s really amazing how few people ever even try to go vegetarian (or vegan) for a day, let alone a week, or let alone trying it enough to be able to compare for themselves any noticeable benefits they might have. For something so important for our health, as well as for empathy and for the environment, it’s just amazing... Plant-based foods are the #RocketFuelOfFood. Three great reasons to #SwitchToVegan / Vegetarian: 1) Health 2) Empathy 3) Environment Reasons against: 1) Habit / tradition? 2) Apathy?

We really need a large stick wrapped in a small amount of foam so that it's not lethal. We can then use that to smack anyone who refers to brokechain as if it were meaningful in any way towards solving a problem. (Using "brokechain" instead of the term that brokechain cultists prefer because 1. it's a solution looking for a problem rather than actually useful technology, and 2. bots key off that word.) What brokechain does that they are wanting here is a procedurally generated non-sequential identifier and a database. Your fish is only going to be tagged with an ID, effectively just a large number, which would be generated by some procedure that ensures it's neither repeating nor sequential. Not being sequential is so that people can't just tag their fish with a number they expect the system to generate in the future. Brokechain does this by working out difficult math problems and assigning the resulting large number to a fish. Unfortunately for this plan, there is nothing stopping an illegal fishery from reading a blockchain's data and randomly assigning existing ID to their fish, which is why decentralization is NOT what you want in an accountability database. An accountability database needs the data to be accessible only via comparison. In a database this is typically done by hashing a value, encrypting it in a way that is not reversible. Then you apply the same hash to the value you want to check and make sure the result matches what you stored. The only current way to break a hash is to have access to the hashing algorithm and generate a large number of comparison samples, which is infeasible for large values. This is why they aren't considered to be particularly vulnerable to quantum computing, nor to most realistic attacks. But critically, the other half of breaking a hash is that you actually have to have the stored hash. When you hear of a breach where people's data is stolen from a hashed database, that usually involves a very large database (called Rainbow Tables) of pre-hashed common text values to compare against the stolen hash. The longer the text strings, the more difficult this becomes (which is why you should be using 16+ characters, not 8). Brokechain would record the value in a hash as well, but it's giving the hash and the hashing algorithm to everyone. That means nobody has to breach any system to start working against the hash. And importantly, they don't need a specific value out of the chain, they only need to break ANY number. With roughly 1 trillion individual fish being caught annually, they only need to guess and confirm via hash checking a few thousand per operation per year. While your fish brokechain is churning feverishly to calculate a specific value, they can spam numbers in the expected range far faster with far cheaper equipment until they stumble upon one that matches an existing hashed value. And because you're relying on brokechain to ensure uniqueness, you have to do this as part of your node generation. For each of the 1 trillion fish. If you don't rely on it for uniqueness, people can generate their own illegal fish IDs in the system using a stolen hash value from a random fishing regulatory body and you'd just have to rely on "trust me, bro" to tell if their registry is real or not within the system. That means even with the smaller impact brokechain designs being used now, the processing power required is going to be insane for something that can be broken by brute force. We have plenty of centralized systems that do this job FAR better in regulating things like banking transactions on global markets. Those operating illegally don't have access to the hashes outside of breaches, and when a breach occurs, the relevant data can be changed and rehashed to prevent ongoing exploitation. And that's without getting into future proofing. Right now, brokechain is scrambling to adopt "post-quantum cryptography" options out of fear that growing available of quantum computers will leave them vulnerable. This isn't the first time cryptographic technology has had to scramble because smart people with improved technology found a way around it, and it won't be the last. Being public and decentralized sounds good in the democratizing feel of those words, but in practice it means that you can't hide things away while you're trying to fix them and you can't replace them without everyone seeing what you did and having an inroad into breaking your newest protection. You can make things secure with open technology, and open source does some wonderful things with this. But storing your DATA openly is not the same. I described brokechain as a "solution looking for a problem" because fundamentally it does a thing that you don't actually want done when you actually think about it. It doesn't democratize things by decentralizing data processing and authority, it just mislabels "I did a thing with my expensive computer" as "authority". It doesn't protect data because the encryption is more vulnerable than proprietary data. And it doesn't ensure agreement over a transaction history, it merely mislabels "first" as if it means "true". All of the things it purports to do are no more true than a politician using stock phrases like "family values". Those of us who actually work in IT have been warning you for years that it's digital snake oil.

All of these systems are great at monitoring those who are most likely to follow the rules. The problem is that fishermen like those from China DON'T FOLLOW THE RULES, nor do they seem to care if they are monitored as they will just move to somewhere that monitoring doesn't exist. On top of all of this, the quantities that they take are so vast that fisheries will have completely collapsed by the time someone can prove what they are doing. If more of the resources that are going into monitoring the rule-followers were used to control the rule breakers and avoiders, we may still have fish around in the future. So, while all of this sounds really cool, it is really tantamount to pissing into the wind.
