Centaur Aliens Lifespan: 80 years Adult weight: 500-1000 kg Adult height: 2.5-4 meters Visual range: near infrared to blue Diet: Obligate hypercarnivores Centaurs' evolutionary ancestors were savanna pack predators who used ambush to hunt prey, nomadically following prey animal herds as they traveled round the global continent every year. Modern centaurs emerged when they started to use tools to help with hunting and land management, eventually resulting in some groups settling down and becoming reliant on fishing, animal agriculture, and food preservation to survive. Centaurs remain obligate hypercarnivores, meaning approximately 70% of a healthy diet is meat and animal products, but they opportunistically supplement their diet with grain, starchy tubers, and small amounts of roughage and vegetation. Similar to humans, centaurs have a bisex reproductive system with an inseminator sex and gestator sex who gave birth to live young, but functionally are more akin to Earth's marsupials. Centaur’s distant ancestors had larvae that lived in the soil like grubs before pupating into adults, and their viviparous silk eating clade first emerged after parental care of the larval stage evolved. While other members of their clade have development and pupation both happen in-utero, centaur litters leave the womb early and feed on their parent’s nutritive silk until they are large enough to pupate, spinning a cocoon on their parent’s back. They emerge as an imago, resembling a miniature adult with the physical capacity of an six-week old kitten. Centaurs are pseudo-eusocial, with a social structure hierarchy somewhat similar to meerkats. At its most basic level a clan consists of one matriarch, a female who is responsible for bearing the clan's young; the entourage, who are the matriarch's partners and usually mostly male; and the clan's "workers," who are not involved in reproduction. These non-reproductive clan members are generally either the matriarch's children, childless relatives, or individuals married in for their skills or political purposes.

Can I ask for more Penguin Danny?
Your wish is my command.
Honestly, I've had this one snippet stuck in my head for a while, so thank you for the excuse to write it ✨
--
Danny sat huddled with a few of the smaller penguins, relaxing into their warm feathers as much as he could as he took in the situation developing before him.
About two months ago, a group of scientists geared up for the harsh cold had arrived in the Arctic. They had taken up residence in the frigid metal building Danny had spent some time in when he first got here, bringing life and warmth to their base that hadn't been there when the teen needed it.
At first, they kept to themselves. Taking water samples from the snow and ice pools that covered the territory. But it was only a week later that they moved on to examining the colony that had taken Danny in. They would pull a penguin or two away from the group, giving them fish and krill while they measured the small creatures and attached a monitor to the animal's sleek feathers, releasing them back to the group to loudly squawk their tales to the rest of the birds.
Eventually, they made their way inwards, away from the penguin hunting hunting grounds and towards their nests. It was then that they saw Danny for the first time.
It had been funny, at first. The coat clad researchers had frozen, before chatting frantically. With how long Danny had spent hiding out in the cold, he wasn't surprised that it took a while to understand what they were saying. It did filter in, though, the longer they hung around. Words that he knew, but didn't make a lot of sense in the limited context he had. Stuff like "baby" and "different" were obvious, especially when they gestured at him as they spoke. But other words, like, "unusually large", and "dangerous" confused him.
Was he a bit bigger than the birds around him? Yes, yes he was. But he didn't think he was unusually large for the species he was supposed to be. Then again, it's not like he had ever actually seen a baby emperor penguin before, so he had no real life reference. But they were big birds! Surely that meant they had big babies? And even if he was bigger than he was supposed to be, how was anything about this situation was 'dangerous'?
It didn't help his opinion of the researchers when they tried to move him away from the flock. Trails of treats were fine and dandy at first, and easily ignored by the teen seeing as he didn't need the same amount of food as an actual baby penguin of his size (perks of being able to feed on ambient ectoplasm). When he didn't seem inclined to follow the trail like some of the others, who had all come back squawking about the researchers manhandling them again, they tried a more straightforward approach.
The teen would never forget the day those puffy coats pushed gently through the throng of black and white bodies until they boxed him in on all sides. His panicked squeaky screeches had immediately attracted the attention of the birds, and those pesky puffy coats had some nice tears in them for the troubles they caused. After that, the researchers found themselves being chased by the entire colony if they came to close, angry screeches drowning out their own panicked yells and occasional yells of pain when a beak managed to find purchase.
As much as he appreciated the colonies fierce protection, the teen should have known that it would draw attention. Those researchers were out here for a reason, probably some sort of documentary on the wildlife that thrived in colder environments. Maybe something about endangered species or global warming. Whatever it was, it had them hanging around, taking pictures and writing in journals.
It should have been more obvious to him that something was bound to happen. Pictures, even when he looked normal to the mortal eye, could easily reveal a different truth. It didn't take long for pristine white coats to appear, scouting the area with ecto-trackers in hand a blasters holstered at their sides.
The confrontation a full month after the researchers arrived was a bit surprising, and it took everything in Danny's new fuzzy body to stop from launching himself at the men in black rip offs when they leveled their blasters at the colorful puff coats.
The puff coats were sturdier people than he thought, though. Instead of backing off, like anyone else would do, they argued. Blocking the easier paths to the nesting grounds, tampering with their equipment while they were distracted with whatever ecto readings they were getting, even resorting to throwing things when the came too close to trampling one penguin Danny had affectionately dubbed 'Steve'.
And now here Danny was. Cozied up with a decent group of mother penguins and their babies while the fathers took their turn to hunt. Watching as the guys in white ran around screaming. The cause of their screams? The child with a sword that was chasing them.
At this point in his (after)life, Danny shouldn't be surprised by anything. And yet, surprising things continued to occur. Maybe he should ask someone if he was cursed or something.
The penguins around him shifted, letting out warbles and startled peeps as they resettled. Danny shook himself, pulling his attention away from the potential murder occuring in front of him to look at the source of his new friend's unrest. And was once again reminded to not be surprised by the surprising things that occured around him.
The half Kryptonian child that sat next to him gave the teen a smile and a gentle pat before turning his attention to where his friend continued to swing his katana, catching one of the scanners and a bit of an agents hand with the wickedly sharp blade. The kid next to Danny winced and cupped his hands over his mouth. "Robin! Remember what Nightwing told you before we left!"
The sword wielding child tisked loudly, the sound muffled slightly by the snow that was beginning to fall, but resumed his fighting with a little more effort in not hitting the agents with his blade. The handle of his sword, however, was used just as effectively. The Kryptonian kid sighed, but didn't call out again, instead reaching out to pet some of Danny's fuzzy brown down feathers.
This was fine, Danny decided. It wouldn't be fine forever, but for now it was. And whatever came after this, he could always try throwing vicious penguins at it. It worked well enough the first time.

Farming carnivorous fish in Europe harms fishing communities in West Africa by depriving them of a resource fundamental to their nutrition and their livelihoods. Salmon are carnivorous, and farmed salmon depend on the nutrients provided through fish oil in particular, gained through grinding up smaller, wild fish. At Feedback, we have evidence that in feeding these smaller fish (sardines, sardinella, ethmalosa, etc.) to Scottish farmed salmon, major micro-nutrient losses occur. How can we allow an industry driving biodiversity loss, environmental pollution, and food insecurity to simply go on with business-as-usual?
[...]
Our research shows that in 2020, nearly 2 million tonnes of wild fish were required to produce the fish oil supplied to the Norwegian farmed salmon industry and that throughout this feeding process, one-quarter of the wild fish ground up is lost. Furthermore, the amount of fish sourced off the West African coast (FAO area 34) to supply fish oil to the Norwegian salmon farming industry in 2020 could have provided between 2.5 million and 4 million people in the region with a year’s supply of fish.
[...]
The extraction of fish from West Africa by corporations headquartered in the Global North for the benefit of mainly high-income consumers in Europe, North America and Asia has far-reaching consequences, further entrenching global inequity and food insecurity. Thus, the continuing expansion of industrial aquaculture is fuelling a type of food imperialism.

The new 'compost obligatoire' rules came into force on 1 January 2024. Here's what they entail.
As of 1 January 2024, organic waste recycling is mandatory in France under new 'compost obligatoire' rules.
With support from the government’s Green Fund, municipalities must provide residents with ways to sort bio-waste, which includes food scraps, vegetable peels, expired food and garden waste.
Households and businesses are required to dispose of organic matter either in a dedicated small bin for home collection or at a municipal collection point. Previously, only those who generated over five tonnes of organic waste per year were required to separate it.
The waste will then be turned into biogas or compost to replace chemical fertilisers. Alternatively, it can be composted at home.
The obligation is currently on local authorities to provide an easy means for households to compost or separate organic waste.
While facilities are rolled out, there will not be fines imposed for non-compliance. It is yet to be seen whether stricter rules will be imposed in future.
One-third of household waste is bio-waste
Organic waste from food and gardens accounts for almost one-third of household waste. When it is mixed with other rubbish, it typically ends up in landfills or incinerators, where it produces heat-trapping greenhouse gases like methane and CO2.
Food waste is responsible for about 16 per cent of the total emissions from the EU food system, according to the European Commission. Globally, food loss and waste generates around 8 per cent of all human-caused emissions annually, the UN says.
It can also contaminate packaging destined for recycling like paper, plastic and glass.
In 2018, only 34 per cent of the EU’s total bio-waste was collected, leaving 40 million tonnes of potential soil nutrients to be discarded, according to NGO Zero Waste Europe.
In France, an estimated 82 kg of compostable waste per person is thrown away each year.
Is bio-waste separation mandatory in other European countries?
Under the EU’s Waste Framework Directive, bio-waste collection is being encouraged this year, but it stops short of setting mandatory targets.
In many European countries, organic waste separation has already been implemented at the municipal level.
Milan in Italy has been running a residential food waste collection programme since 2014. Households were given dedicated bins and compostable bags to kick off the scheme.
Elsewhere, taxes or bans on incinerating bio-waste have encouraged similar schemes, with separate bins and home composting widespread in Austria, the Netherlands and Belgium.
The UK announced plans to roll out separate food waste collection in 2023. It remains voluntary for households in England, but is more strictly enforced in Wales and for business owners.
How to sort your bio-waste
Ideally, all waste - including organic matter - should be kept to a minimum.
This can be achieved through careful meal planning. Consuming, freezing or preserving food before it expires along with using every part of an ingredient also help to reduce waste. Some food waste can even be repurposed into animal feed.
Any food waste that cannot be saved or repurposed should be either composted or separated for collection. This includes uneaten food scraps, baked goods, dairy products, eggshells, fruit and vegetables and their peels, mouldy food, pet food, raw and cooked meat and fish, bones, tea and coffee grounds.
Liquids, non-food products and packaging should not be placed in bio-waste bins.

#tfw you're too comfy to run away
Snailfishes are found globally in all ocean basins, from shallow intertidal waters to the deepest depths of the ocean to unsuspecting crabs that often serve as hosts to tiny snailfish eggs. These slightly annoying but adorable fishes are well-adapted to a variety of habitats, including rocky outcrops, the muddy seafloor, and even the midwater. They play an important role as prey and predator in many ecosystems. Most snailfish species are small and feed on tiny invertebrates, but larger species may prey upon other fishes. MBARI has observed over a dozen species of snailfish in the past 34 years of exploration. We suspect there are dozens more out there waiting to be discovered.

Great Hammerhead
Diet
A Great Hammerheads diet is comprised of a wide variety of animals. These sharks are opportunistic apex predators. They feed on invertebrates such as crabs, octopus, lobster, squid and bony fish like catfish, tarpons, groupers, sardines and porcupine fish. They also eat smaller species of hammerhead.
While they have a diverse diet, their favored meals are stingrays! They're able to find the stingray using the electro receptive organs in their cephalofoil and they attack it by pinning down the ray with its head while feeding on the wings.
Habitat
The great hammerhead is found throughout the Atlantic, Indian, and Pacific Oceans. They are also found in the Mediterranean Sea. They migrate seasonally, in the summer they head towards the poles in search for cooler water and in the winter they migrate back towards the equator in search of warmer water.
Species
There are a total of 10 species of hammerhead (This video is mainly about great hammerheads But I thought I should include a species slide^^)
1. Great hammerhead
2. Smooth hammerhead
3. Scalloped hammerhead
4. Scalloped bonnethead
5. Winghead shark
6. Scoop head shark
7. Bonnet head shark 8. Small eye hammerhead 9. Carolina hammerhead
10. Whitefin
Shark finning
shark finning is a problem that affects not just hammerheads, but many other sharks. Great Hammerheads just happen to be vulnerable to shark finning due to their large fin size. Shark finning is when a shark is caught, their fins are cut off, and then they re usually thrown back into the ocean to drown and suffocate. 73 million sharks are killed each year for shark fin soup. It is illegal in the us but other countries do not have laws against it. A way that we can help save sharks is to stop buying shark products! Here is a tiny list of things that could possibly contain shark.
Garden fertilizer
Hair dye+ shampoo
Skin lotion
Souvenirs (shark teeth)
Lip balm
unfortunately I am not sure of the brands that use shark so I can't tell you which ones to not buy from: (
Conservation
Great hammerheads are listed as globally critically endangered on the IUCN Red list. They are vulnerable to overfishing and are threatened by the global shark fin trade because of the large size of their fins. The skin of this shark can also be used for leather and its liver for rich vitamin oils. Over 90% of Hammerheads die once they are captured by targeted fisheries. They are endangered in the Gulf of Mexico, North West Atlantic, and in the South West Indian Ocean. Great Hammerheads unfortunately do not reproduce often so they are not quick to recover after overfishing.
(I made this for anyone who prefers the info this way)

Hello! Me again! I’ve finished writing another story. Again, any constructive criticism and feedback is appreciated! I’m also thinking of making another part to both the stalker story and this one. If anyone is interested in something like that please comment, dm me or send a request! As always sorry for any errors, I’m slightly dyslexic and if I missed anything in the warnings please tell me so I can fix it! (Also if anyone has any requests please don’t hesitate to send one in! I’m trying to grow my account and be better at writing so requests are very helpful!)
Tw: merman, general Yandere behavior (body horror? No gore just a very unique merman)
Gn reader (referred to with they/them pronouns!)
The seagulls screeching above are oddly comforting. Over my time as a researcher, I've learned that if the seagulls aren’t flying overhead, a storm is near. And luckily for me, the seagulls are in the sky and very vocal. I grab a shrimp from my dads cooler and throw it up towards the birds, watching one swoop down and grab it before joining the others. I always admired how intelligent they were, following boats in the hopes of getting food. I reach back into the cooler for another shrimp before my dad yells at me, “Hey!” I whip around at his voice, “Don't waste all our bait on some gulls! If you keep feeding them, they're going to swoop down and eat all our shrimp!” I giggle at his words. He's always lectured me about feeding the birds. The boat slows to a stop and my dad leaves the wheelhouse and lowers the anchor as I take my sweater off and put my flippers on. I wore my favorite sweater over my wetsuit, the wind out at sea surprisingly cold.
My dad sets up his fishing rod at the edge of the boat and I go to the other side to avoid his fishing line. He always fishes when I go diving, not to eat but to keep himself entertained while I'm gone. He never keeps the fish, just writing down the type of fish, how big and how old he thinks it is before throwing it back. He has multiple notebooks he keeps on his boat from years back when mom would go diving. She was always my role model, she was the reason I got my degree in marine biology and my scuba permit. She was the reason behind gaining a passion for fish, the reason my room was filled to the brim with marine animal stuffed animals. She had to stop diving, when I was young she got sick, and it was too dangerous for her, but that's why I'm here. I'm going to continue her studies for her, so she can still see the ocean she loved so much from her bed.
Putting my goggles and mouthpiece on, I excitedly roll off the deck and into the water. Right below me is a magnificent coral reef filled to the brim with color. Hustling and bustling with fish of all colors of the rainbow. Clown fish in the anemones, iridescent parrot fish, yellow butterfly fish, stripped Angelfish, a few yellow finned Damselfish, Surgeonfish and small Goby all swimming in and out, over and under the coral. I take out my camera and snap a few photos, not just for mom, but also for the other researchers back at the lab. They sent me out with a few videography robots to study the effects global warming has had on the reefs, but I don't think they'd mind if I snuck a few to my mom. I drift further and further away from my dads boat, distracted by taking photos.
A few photos of the vibrant parrot fish, a few of clown fish seeking residence in sea anemones, a few of the small goby fish and a lot of the vibrant coral. I keep wandering further, always keeping the boat in view when something catches my eye. A hole. A large hole. No, not a hole, a sea cave. I peer inside and see dots of color. I wouldn't hurt to venture in, would it? For science, I tell myself, for research and the betterment of knowledge, I tell myself, but I know I'm just too curious for my own good. Upon my entrance I see various seaweed, algae and sea sponge species. The further I go, the less light. The less light, the more things produce their own. I see a few small fish and algae glow but something big catches my eye, something really big, too big, and oh so colorful. Swirls of orange and blue and too humanoid to be a fish, but too fish to be human. It has what looks like hair, long and glowing blue on one side and orange on the other, with many streaks of the opposite color mixed in. a long tail with swirls of the same colors, and it goes up it's body onto what looks like a torso and arms. It has arms? Why would a fish have arms? Cave dweller or not, fish are not supposed to have arms.
I quickly pull out my camera, I have to document this. What I didn't account for was the automated flash, it has a light sensor and if it's too dark, the flash turns on. Suddenly the cave is lit up with light from my camera. I panic and fiddle with my camera, trying desperately to turn off the automated flash, but my efforts are in vain. A clawed hand grabs the lens, and I turn my attention to the creature in front of me. A wave of fear washes over me as I look up to a humanoid face, my heart rate picks up as I notice the scowl he wears. I start to hyperventilate as he leans in closer and reaches a hand out towards my face. A clawed hand coming towards my face. He's going to hurt me, isn't he? My fight or flight kicks in and in my panic I choose fight.
I quickly raise my legs and kick him in the stomach, making him curl into himself and let go of my camera and propelling me away from him. While he's distracted, I grab my falling camera and rush out of the cave and towards the boat. I didn't notice how late it's gotten, the sun setting over the horizon as I pull my self out of the water and onto the ledge. I quickly dislodge my mouthpiece and throw my goggles further onto the boat, trying to regulate my breathing once again. What was that? Human? Fish? Some kind of sick hybrid? Should I tell dad? Tell the team? Did I even get a clear picture of that thing? If news gets out, what will the press say? What will the scientists do? If it has the conscience of a human, it will be cruel to report on it. What if someone hurts them? Kills them? What do I even do?
My thoughts are broken by my dads voice, “Everything alright?” he always asks that after I come up, but he sounds worried this time. “Yeah… Yeah, I'm fine.” I'm lying through my teeth, I know it, and I'm pretty sure he knows with the look he gives me “Well, if you're sure. I made dinner while you were gone. It's on the table whenever you're ready.” he tips his hat and walks away, presumably to go eat the aforementioned dinner. I sigh and take off my oxygen tank, hanging it with the others before going below deck to take a shower.
My dad snores in his bed as I eat the dinner he made. Vegetable dumplings with a side of soy sauce and ramen. Simple, easy to make and oh so good. He always made the best food. I'm scrolling through my camera roll as I eat, checking if my team can use any of the photos I took when it pops up. I almost drop my dumpling when I see it. The creature on my camera roll, slightly blurry but still visible with glowing eyes. I want to throw up. He's objectively beautiful, but he's earth shaking. Merfolk aren't real, they're evolutionary impossible, and yet here he is. I suddenly don't have an appetite anymore, it's too much to handle. I put my food in the fridge and lay in my bed. What am I going to tell my team? What am I going to tell dad? That despite every odd on the planet, merfolk are real, and I had an encounter with one? They're going to think I'm crazy, right? What about the picture? Would that really be enough proof for them? Would they accuse me of editing the picture? What possible excuse could I come up with to explain it? If they do believe me, I don't want them to hurt him. Would it just be best to delete it? Export the photo off the camera and keep it for myself? These thoughts keep me up well past my bedtime.
Something is off. I feel like I'm being watched. I turn my gaze from the ceiling to the glass floor. It's him. The thing from the cave. It smiles, reveling razor sharp teeth. What have I gotten myself into?
++++++++++++++++++++++++++++++
They're mine. It was set in stone when we met.
When I heard of the cave shells, I knew I had to check it out. Supposedly there were shells that glow in the dark and I just had to get my hands on one. Avoiding the moray and brushing aside small lantern fish, I make my way deep into the cave. I've been there for a solid hour, going from tunnel searching the sand. I was getting frustrated. Where are those shells?! A flash catches my attention. Whipping around, I see a human. They look exactly like the rumors. Humans are real? And what's that box in their hand? What was that light? Was it a mating signal? Do they like me? I swim over to investigate the box, laying my hand on it, the thought crosses my mind. This was probably a mating gift! Immediately after I realize what it is, they kick me and swim off with the box. Humans must be a species that want to be chased before they mate!
I quickly swim after them when they go up above the water onto a strange piece of metal. That must be their home! My suspicions are proven correct when I see them sitting in a strange object and eating. Merfolk only eat in their homes, so it must be the same for humans. They crawl onto something squishy and cover themselves with something.
I dare to get closer to them, my face bonks against something clear, this must be the glass the other merfolk were talking about. I place my hands upon the glass, watching my mate. Eventually they look down at me, my friend Erin told me humans like when you smile, that smiling was a show of friendliness to humans.
Rest assured, little human, the next time you're in water you will be mine. Our mandarin babies will be so cute!~
(Merman is based off a mandarin fish, look them up! Very unique fish!)

Fish of the Day
Today's fish of the day is the atolla jellyfish!
The atolla jellyfish, also known as the coronate medusa, alarm jellyfish, and deep-sea jellyfish, scientific name Atolla wyvillei, is a crown jellyfish (from the order Coronate) found in deeper waters. (Note: Atolla jellyfish may refer to several species of atolla, but Atolla wyvillei is the most commonly found globally.) The atolla jelly is one of the most commonly found jelly in the depths, living in the midnight zone (1,00 to 4,000 meters below the surface) across the globe! Although, they can be found as high up as 300 meters below the surface, we still know little about them due to their depth range.
Most well known about these jellies is their bioluminescent response to predation. When this jellyfish is threatened or disturbed, a blue-green bioluminescence lights up, lighting up the predator. The visual is that of several rings flowing down the bell of the jelly, I would recommend looking up a video, it's quite stunning! This confuses the predator, shocking it into halting its attack, and giving off the illusion of multiple jellyfish in the area. However, this lightshow also acts as a calling for larger predators, lured in by the lights, the attacker of the jellyfish is far better prey to larger animals. Allowing the atolla jelly time to retreat. In the early 2010's this was used by marine biologist Edith Widdler to invent the E Jelly, a device which mimics the luminescent patterns of the atolla. The E Jelly has since been successful in luring animals, and its use provided us with the first ever video of a live giant squid in 2019.
The atolla feeds on crustaceans and shrimp, along with floating nutrients around them. The jellyfish has 20 marginal tentacles and a trailing tentacle, which is larger and thought to be used in catching prey. Reproduction can be done both asexually, and sexually, using the trailing tentacle to pull themselves towards a mate and attach temporarily. They grow between 20-180 mm (about an inch to 7 inches) in diameter along the bell, and although tentacle length is currently unknown, it is estimated to be 10 inches at most.
Have a wonderful day, everyone!

Spectember 2024 Day 22: Imperial Greatsword
At 16-18 meters long and about three to six tons in weight, the Imperial Greatsword is the largest species of the billfish genus Megaxiphias or Greatswords, Enoch are very distant relatives of the sailfish and swordfish that have specifically evolved to feed upon swift, fast-moving prey up to the size of a beluga Potworia’s second-largest Bony fish species after the Regal Doublefin, and one of the largest, fastest and most fearsome predators ever to swim across the planet’s seas. Megaxiphias imperator inhabits the cold, temperate southern hemisphere half of the vast global ocean that separates one end of Jariloia from the other, and it hunts schooling fish, the slightly larger creatures that are attracted to them such as the wolf-fish, a few species of trevally, as well as swimming coastal parachiropterans. As it does so, the giant fish raises a huge, colorful sail which reduces sideways oscillations of its head, and thus enable the 5-meter-long bill, which can be used to impale prey animals in a similar fashion to Vlad lll’s infamous execution method, to be less detectable to them.
The Imperial Greatsword is capable of accelerating at burst speeds of up to 40 km/h, and it uses its bill to hit its fast moving prey by tapping at them at short-range movement or by slashing at them via long-range horizontal movement. It is also during some of these rapid pursuits that the giant, macropredatory fish will sometimes breach the surface of the water 5 meters high into the air, much like a great white shark or a humpback whale, with the prey animal finally caught in its jaws.

In August 1963, the Dutchveterinarian Dan (E.H.) Kampelmacher stepped on a plane to Lima, the capital of Peru. His destination: smelly factories in Lima’s port city which ground up tiny anchovy fish from the Pacific Ocean into huge amounts of animal feed. Peru exported one fifth of this ‘fishmeal’ to the Netherlands, where farmers used it to feed their quickly rising numbers of chickens and pigs in new intensive livestock or ‘factory’ farms. [...]
The ports of Lima and Rotterdam connected the ecosystems of Peruvian fishmeal plants and Dutch farms. [...] [H]ardly anyone showed any interest in what the stuff was made of. Although Dutch farmers had started to refer to their new industrial poultry and pig farms as ‘landless’ at this point in time, they did not intend this phrase to mean their growing dependence on oceans rather than land. Rather, it characterized a fundamental change in livestock farming: in the postwar era farmers could increase their numbers of animals independently of the area of land they had for growing feed. The phrase ‘landless’ erased from view that these farms in fact depended on places elsewhere on the planet. [...] [T]he fish, called “anchoveta” [were] from the Humboldt Current ecosystem [...].
Fishmeal was invisible, despite its crucial importance for two interrelated major changes in the Netherlands and the global north in general: the rise of intensive livestock farming, and the unprecedented increase in the consumption of meat and eggs. [...] How did fishmeal and its environmental impacts connect industrial livestock farming in the global north to its production places in the global south [...]? [...]
---
Shadow places are ‘all those places that produce or are affected by the commodities you consume, places consumers don’t know about, don’t want to know about, and in a commodity regime don’t ever need to know about or take responsibility for’. It is very similar to the ‘ghost acres’ concept used by environmental and global historians: the acres of land countries used elsewhere on the planet [...]. Cushman analyses the rise of the Peruvian fishmeal industry as another case of what he calls ‘neo-ecological imperialism’: the ‘Blue Revolution’ [...], to stress the connection between fishmeal production in the Pacific World and the rise of industrial livestock farming in the global north. [...]
Fishmeal fed the twentieth-century shift to industrial livestock farming – the Netherlands was among the top three fishmeal importers internationally from 1954 to 1972. [...] Animal proteins – and fishmeal in particular – played an essential role in this shift to industrial livestock farming [...]. But for poultry and pigs, animal proteins were an ‘indispensable ingredient’ [...]. Internationally, fishery landings tripled in the period 1950–1973 due to the rise in fishmeal production for animal feed. [...] During the Peruvian fishmeal boom from 1958 until 1970, [...] [t]he livestock sector started to refer to it explicitly as ‘Peru fishmeal’ [...]. The Netherlands was the second-largest importer after the USA in 1955 [...].
---
According to Cushman and Wintersteen, the spectacular rise of the Peruvian fishmeal industry was the result of [...] international interest in the Peruvian stocks of small fish suitable for fishmeal production, interest from the USA in particular.
After the collapse of the Californian fishmeal industry shortly after the Second World War, industrial fishmeal plants in Peru were realised with American marine expertise, investments by American industrialists, subsidiaries of American companies like Cargill and Ralston Purina, and second-hand American fishmeal equipment and technology. [...]
As a result, the Peruvian fishery industry changed radically during the 1950s. Rather than a being a by-product of fish canneries, fishmeal became its core focus. [...] [A]nd industrialists moved in entire fishmeal plants from the USA and Scandinavia. These plants could turn 5.4 tons of fish into a ton of fishmeal at the peak of the industry [...].
---
Angola exported fishmeal under Portuguese colonial rule (until 1975), and South Africa exported fishmeal during Apartheid (until 1994). In Chile the neoliberal dictatorship of general Augusto Pinochet (1973–1990) gave fishmeal industrialists free rein again from 1973 onwards, and Chile had replaced Peru as the major fishmeal exporter by 1980.
Social inequality was exacerbated [...]. Fishmeal industrialists made enormous amounts of money, and stock exchanges in the global north enabled speculation on fishmeal. Simultaneously, workers in the fishmeal plants were poorly paid and lived in slums with no paved roads, running water or electricity, unhealthy conditions and polluted air. Fishmeal’s volatile market resulted in labour unrest during the 1960s in Peru, and during the 1980s in Chile. [...] Many factories were moved to less-regulated places along the coast, taking the air pollution and resulting public health problems with them. One of these places was the city of Chimbote, which quickly grew into the largest fishmeal city of Peru, and became ‘one of the nation’s … most polluted cities’. [...] One place impacted by the feeding of fish to farm animals was in particular in shadows: the marine ecosystems from which the tiny fish were taken, like the Pacific Humboldt Current along the coast of Peru and Chile. [...]
The ocean ecosystems in the global south exploited to feed the industrial livestock sector in the north remained largely invisible. [...] The disappearance of the Peruvian anchoveta also made the ‘protein crisis’ move north. The Dutch livestock sector referred to the ‘true emergency situation’ of the Peruvian fishmeal crisis as the ‘protein crisis’ (‘de eiwit-crisis’). [...] But in 1972–1973 the Humboldt Current marine ecosystem created its own shadow places in both the north and the south. The extraordinary strong El Niño led to the sudden disappearance of the anchovy population [...].

This land isn’t for you or me. It’s for the meat industry.
The programs that subsidize the beef industry represent some of the most striking examples of America’s tradition of “agricultural exceptionalism” — giving farmers and ranchers special treatment, like sweeping exemptions from critical environmental, labor, and animal welfare laws. Agribusiness also benefits from getting large swathes of the West to itself, illustrating a simple fact of land use in America: Contrary to the famous Woody Guthrie song, much of it isn’t for you and me — it’s for the meat industry. The federal government’s livestock grazing program is just one part of America’s agricultural land use story. The other part is all the land used to grow crops to feed farmed cattle, chickens, pigs, and fish, which comes in at 127 million acres. All told, a staggering 41 percent of land in the continental US is used for meat, dairy, and egg production. Globally, it’s more than one-third of habitable land. Much of it was once forest that’s since been cut down to graze livestock and grow the corn and soy that feeds them. ... Agriculture is land-intensive, and we need food. But not all agriculture is equally land-intensive. Meat-heavy diets require far more land than low-meat and vegetarian diets. If we ate less meat and more plant-based foods, we’d free up a lot of land, and we could use it to make a huge dent in climate change. To avoid the worst effects of climate change, it won’t be enough to just reduce the amount of greenhouse gasses we spew into the air — we also need to remove them from the atmosphere. One effective way to do that, which doesn’t rely on unproven carbon capture technology, is by “rewilding,” or retiring agricultural land back to its original ecosystem so that its vegetation can sequester carbon dioxide. Much of that potential is currently wasted on inefficient livestock production.

Good News - May 8-14
Like these weekly compilations? Support me on Ko-fi! Also, if you tip me on Ko-fi, at the end of the month I'll send you a link to all of the articles I found but didn't use each week - almost double the content!
1. Critically endangered fish with red hands and 'sad toad face' returned to the wild in Tasmania
“Conservationists in Australia are celebrating the return of 18 critically endangered red handfish to the sea after they were taken into care at the Institute for Marine and Antarctic Studies (IMAS) in January to protect them from marine heatwaves.”
2. A rare Australian marsupial is being genetically modified to save it from extinction. Here's how
“Scientists are trying to genetically 'edit' the endangered northern quoll to make it resistant to the neurotoxin of the invasive cane toad. […] Now experts in gene-editing […] say they can introduce genetic resistance to the toxin by taking DNA from a species of South American lizard and ‘edit’ that into the cells of a northern quoll. They have already managed to do this with the cells of the closely related dunnart, another endemic marsupial.”
3. More and faster: Electricity from clean sources reaches 30% of global total
“For the first time, 30% of electricity produced worldwide was from clean energy sources as the number of solar and wind farms continued to grow fast. [...] Some of [the past year’s] new demand was for heat pumps, which are an efficient way to both heat and cool buildings, and for electric vehicles. [... Last year was also] the 19th year in a row that solar was the fastest-growing source of electricity generation.”
4. Standards Established To Improve Health Care For Kids With Disabilities
“Developed by a panel of health care experts, adults with disabilities and caregivers, the plan published recently in the journal Pediatrics […] calls for providers to be trained about caring for those with neurodevelopmental disabilities, improved communication with patients and their families and proactive planning in advance of health care encounters to ensure that patients are at ease and provided accommodations.”
5. Working together to better understand Alaska’s beluga whales
“Beluga conservation efforts depend on an accurate count of whales. Indigenous hunters also need to know how many belugas there are so that they [can] decide how many can be safely harvested. That’s why WWF is bringing together Western science and Indigenous knowledge […. U]sing hydrophones to detect belugas in the Yukon River works—and it is an approach that is both cost-effective and non-invasive.”
6. Robotic system feeds people with severe mobility limitations
“Researchers have developed a robotic feeding system that uses computer vision, machine learning and multimodal sensing to safely feed people with severe mobility limitations, including those with spinal cord injuries, cerebral palsy and multiple sclerosis. […] The robotic system successfully fed 13 individuals with diverse medical conditions in a user study spanning three locations[….] Users of the robot found it to be safe and comfortable, researchers said.”
7. Senate Passage of America’s Conservation Enhancement Act a Win for Wildlife
“The Senate’s reauthorization of the America’s Conservation Enhancement (ACE) Act will benefit America’s wildlife and way of life. Led by Senators Tom Carper (D-Del.) and Shelley Capito (R-W.Va.), the bill invests in wetlands and habitat restoration projects across the country as well as strategies to reduce conflicts between wildlife and livestock. […] The passage of this bill shows us once again that Americans are united on the need to protect wildlife and our outdoor heritage,” said Andrew Wilkins, director of land conservation policy at the National Wildlife Federation.”
8. Liberals and conservatives differ on climate change beliefs--but are relatively united in taking action
“The study, led by researchers at New York University, finds that when given the opportunity, liberals and conservatives take action to address climate change at roughly the same levels -- and that this is due to conservatives choosing to take action despite their climate-change beliefs rather than liberals failing to act on theirs.”
9. Democratic state attorneys general are teaming up to protect abortion access
“A group of Democratic attorneys general are working to strengthen state-level protections for abortion, contraception and gender-affirming care. These protections could include expanding the use of so-called “shield laws,” which assert that states where abortion or gender-affirming care are legal won’t cooperate with out-of-state efforts to prosecute anyone who helped provide treatment.”
10. Antwerp gives residents free trees
“The Belgian city of Antwerp has 2,000 trees to give away, and it wants to give them to residents to plant in their gardens [...] with the aim of involving citizens in the greenifying process of the city. [...] What’s more, the city website offers practical advice on how to proceed with planting and caring for the tree so that it will meet the standards set by the municipality. [...] The City makes sure to give dead trees a second life by using their wood in the making of natural kids’ playgrounds.”

wrote up a whole thing on salmon for my friend @wherethatoldtraingoes2 so figured i would share. keep in mind there might be inaccuracies this is all straight from my evil twisted mind
so before we get into the history of salmon farming, we gotta look at 18th century and talk about a man named robert bakewell so bakewell was an english farmer who changed the way people bred livestock by introducing selective breeding with sheep before bakewell, most farmers just let animals breed however they wanted but bakewell realized that if he picked the best animals to breed, he could create sheep that were bigger, had more meat, and better wool his methods completely changed farming and became the basis for modern animal breeding eventually, these ideas found their way to fish farming, particularly in norway, where salmon farmers took bakewell’s selective breeding techniques and applied them to salmon by controlling which fish were allowed to breed and in what conditions, norwegian farmers were able to produce salmon that grew faster and were more suited to farming environments than wild salmon it was all about efficiency—creating more fish in less time with fewer resources and in many ways they pulled it off, just like bakewell did with his sheep righr
salmon farming as we know it really started to take off in the 1970s, though the practice itself stretches back centuries, if not millennia, to indigenous peoples in the pacific northwest who had been managing salmon runs long before the arrival of european settlers!!!! but the industrial scale farming that now dominates the industry was born in norway, where the cold, clean waters and deep fjords provided the ideal environment for salmon aquaculture (yayyy)
norwegian scientists and entrepreneurs began experimenting with breeding salmon in captivity after the collapse of wild fisheries due to overfishing and pollution . the reason it worked better than the sheep is simply bc salmon reproduce so fast and have so many babies compared to like sheep or cows so the advances in efficiency happened way faster and with way more strains of salmon to choose from. rught so during the 20th century they developed methods to breed and raise salmon in ocean pens, which allowed them to mass-produce fish to meet growing demand by the 1980s, salmon farming had spread to scotland, canada, and chile (current second biggest producer i think) creating a global industry that produced millions of tons of fish every year by the 1990s, the boom had begun, and salmon farming was celebrated as a solution to the world's hunger for fish without further depleting already strained wild populations
but the expansion of salmon farms has come with a slew of environmental and social consequences the dense concentration of fish in the pens creates an ideal breeding ground for DIESEASESSSSS, parasites, and pollution …. sea lice infestations are one of the most notorious problems cause they often spread to wild salmon passing near the farms, weakening the wild fish populations that are already vulnerable due to habitat loss and climate change etc etc etc we’re overdeveloping our waterways that salmon have relied on for FOREVER. salmon farms also release vast amounts of waste into the surrounding waters like uneaten food, feces, and chemicals used to treat diseases so this can lead to eutrophication which js a process where excess nutrients in the water create algal blooms that deplete oxygen levels, harming local ecosystems and killing off marine life :(( oh and the feed used for farmed salmon often relies on wild-caught fish like anchovies and sardines, which means that farming salmon doesn't actually reduce pressure on wild fish stocks—it just shifts the burden to other species!! crazy!!!
then there's the issue of escapees in rough weather or when nets tear, so farmed salmon can escape from their pens and mingle with wild populations in places like norway and canada, these farmed fish can interbreed with wild salmon, diluting the genetic pool and making the wild fish less fit for survival cause the farmed salmon are bred to grow quickly and resist diseases, but in the wild, they can disrupt the delicate balance of local ecosystems bc they compete with native species for food and spawning grounds in some places, like chile i think. farmed salmon are an entirely non-native species, and their escape has led to the establishment of feral populations that are altering local food chains because farmed salmon are literally like a whole speetare thing at this point compared to wild salmon
then there there are human costs too cause rise of industrial salmon farming has displaced small-scale fishers and indigenous people who relied on wild salmon runs for their livelihoods in places like alaska and scotland, fishing communities that once thrived on the seasonal rhythm of wild salmon harvests now find themselves sidelined by multinational corporations that control the aquaculture industry the sheer scale of salmon farming has made it difficult for wild-caught fish to compete in the marketplace cause farmed salmon are cheaper to produce and can be sold year-round, while wild salmon are seasonal and much more expensive to catch for obvious reasons. this shift transformed the global salmon market and altered the cultural significance of the fish in many regions where salmon fishing was once a way of life,,, leaving places feeling. placeless
so rn salmon farming produces more than two-thirds of the world's salmon consumption im pretty sure BUT it remains a highly controversial industry while some see it as a necessary response to the growing global demand for protein, others view it as an unsustainable practice that is wreaking havoc on both the environment and traditional fishing communities as well as like there was some stuff about health problemss . is that good . yayy. slaamon

Well, hello, Cutie McCuteface 😍
Snailfishes are found globally in all ocean basins, from shallow intertidal waters to the deepest depths of the ocean. They are among the most common fishes living in deep-sea trenches.
These scaleless fishes are well-adapted to a variety of habitats, including rocky outcrops, the muddy seafloor, and even the midwater. They play an important role as prey and predators in many ecosystems. Most snailfish species are small and feed on tiny invertebrates, but larger species may prey upon other fishes. Learn more about these fantastic fishes on our YouTube channel.
