invasive species – Pain In The Bud

The Literary Hub story starts off with a provocative question: what if cats ruled the world?

This is a question I find amusing to ponder, so instantly my mind was filled with images of cats scandalizing foreign heads of state by insouciantly swiping gifts off tables, angering diplomats by yawning and nodding off during summits, and financing the construction of massive and unnecessary coastal walls, on the off chance the ocean decides to move inland and get them wet.

Then the writer cited the repeatedly-debunked “study” that credulous media of all stripes still reference without bothering to read the text — that infamous 2013 Nature Communications paper, published by birders who author books with titles like “Cat Wars: The Consequences Of A Cuddly Killer.”

Some journalists don’t know any better, some are overworked, and some are frankly too lazy to read the study with a critical eye, but I think one of the more likely reasons people continue to cite the paper is because it’s easier to blame felinekind for wildlife extirpation than it is to admit we’re the primary culprits. After all, according to the WWF’s most recent annual review, we’ve killed off 73 percent of Earth’s wildlife since 1970, and we certainly didn’t need house cats to help us push elephants, rhinos, every species of higher non-human primate, and innumerable other species to the brink of extinction.

We did that. We did it with our relentless development, consuming and fracturing wild habitats. We did it with careless industrialization, by dumping chemicals and garbage into our rivers and lakes until more than half of them were rendered too polluted to swim in or drink from. We did it by bulldozing old growth forest and jungle, by exploiting species for fur, folk medicine, ivory, sport hunting and in the illegal wildlife trade.

More than 47,000 species — that we know of — are headed toward extinction. It’s so much easier to blame it on anyone or anything else than admit we need to make major changes to our lifestyles and policies.

But don’t take my word for it. Here’s what Alley Cat Allies has to say about the 2013 meta-analysis and its derivative papers:

“The Smithsonian-funded study published in Nature Communications is not rigorous science.
It is a literature review that surveys a variety of unrelated, older studies and concocts a highly speculative conclusion that suits the researchers’ seemingly desperate anti-cat agenda. This speculative research is highly dangerous. It is being used by opponents of outdoor cats and Trap-Neuter-Return (including the authors) to further an agenda to kill more cats and roll back decades of progress on TNR. And it is being spread unchecked by the media.“

Here’s what a group of ethicists and anthropologists wrote about the claims against cats in the journal Conservation Biology, lamenting the lack of nuance and danger in arguing that cats must be stopped “by any means necessary.” The drive to blame felines, they argue, has “fueled an unwarranted moral panic over cats”:

“Contrary to Loss and Marra’s claims that the scientific consensus is consistent with their views that cats are a global threat to biodiversity, the actual scientific consensus is that cats can, in certain contexts, have suppressive population-level effects on some other species (Twardek et al. 2017). This is something that is true of all predators, native or not (Wallach et al. 2010). Thus, cats should not be profiled as a general threat a priori and without reference to important factors of ecological context, situational factors, clear definition of harms, and evidence thereof.”

“There are there are serious reasons to suspect the reliability of the new, extreme cat-killer statistics,” wrote Barbara J. King, retired chairwoman of the department of anthropology at The College of William and Mary.

Like we’ve often noted here on PITB, the authors of the Nature Communications study can’t even say how many free-ranging felines exist in the US. They say it’s between 20 and 120 million. That’s a 100 million difference in the potential cat population! How can they tell us how many birds and mammals are killed by cats if they can’t even tell us how many cats there are? No amount of massaging the numbers can provide an accurate picture if the initial data is shaky or nonexistent.

Furthermore, the nature of a meta-analysis means the authors depend on earlier studies for estimates on predatory impact, but the 2013 Nature Communications paper does not include any data —not a single study — on feline predatory impact. In other words, they have no idea how many animals free-ranging cats actually kill.

In authentic studies that actually do measure predatory impact, the data varies widely in geographic and demographic context. Data derived from the D.C. Cat Count, for example, shows that cats living more than 800 feet from forested areas rarely kill wildlife, and are much more likely to kill rodents.

Those who cite the bunk study and its derivatives are “demonizing cats with shaky statistics,” King wrote, adding she was alarmed by “an unsettling degree of uncertainty in the study’s key numbers.”

Ultimately, we agree with Wayne Pacelle, former president of the Humane Society of the United States.

The meta-analysis authors “have thrown out a provocative number for cat predation totals, and their piece has been published in a highly credible publication, but they admit the study has many deficiencies. We don’t quarrel with the conclusion that the impact is big, but the numbers are informed guesswork.”

Cats do have a negative impact on wildlife, it varies according to local circumstances, and those of us who love cats have a responsibility to keep our pets indoors and help manage free-ranging populations.

But cooler heads must prevail, approaches to managing cats must be evidence-based, and the effort requires people of all kinds working together — which becomes much more difficult when agenda-driven pseudoacademics whip people into a frenzy by portraying felines as bloodthirsty, invasive monsters who need to be wiped out “by any means necessary.”

When that kind of rhetoric drives public policy, you get countries like Australia killing two million cats by air-dropping poisoned sausages, vigilantes gunning down cats with shotguns in public parks, and local governments offering cash prizes to children who shoot the most cats and kittens. Those efforts aren’t just cruel and inhuman, there’s not a shred of proof that they do a damn thing to help other species.

Solving the problem of free-ranging cats requires us to own up to our own role in species extinction and to take measured, evidence-based steps to protect vulnerable wildlife. Otherwise, we’re inflicting a whole lot of suffering on sentient creatures and accomplishing absolutely nothing.

Homo sapiens are an invasive species who do irreparable harm to the environment and other animals on an unprecedented scale, a new study by the Feline Science Institute has found.

The results prompted feline scientists to add homo sapiens, commonly known as humans, to a database of destructive and invasive animals maintained by the Academy of Scientific Studies.

Cat scientists have only just glimpsed the breadth of human-initiated impact on other animals, Dr. Oreo P. Yums, lead author of the newest research paper, told reporters.

“We found humans are astonishingly, almost indescribably destructive,” Yums said. “For instance, although they fret about birds, humans kill more than a billion of them a year just with their skyscrapers, which birds are prone to fly into due to their mirrored surfaces. Add in wind turbines, cell towers, power lines, habitat loss and slow die-offs due to chemicals, and by conservative estimates we’re talking about billions of birds killed by humans every year without even tallying active measures like hunting.”

Humans have killed off an estimated 70 percent of the world’s wildlife in the last 50 years alone and show no sign of stopping. Oceans are overfished, animals like pangolins and big cats are ruthlessly hunted to extinction to feed demand within the Chinese traditional medicine market, and human addiction to palm oil means the “two-legged demon monsters don’t even have sympathy for their fellow primates,” mewologist Charles Clawin said.

“In Borneo and Sumatra there are entire schools, filled to capacity, for critically endangered orangutan babies who were orphaned by human contractors clearing ancient jungles to make room for more palm oil plantations,” he said. “Often, the humans use industrial equipment to tear down trees while the orangutans are still in them. Other times, they dispatch the mothers with pistols, not realizing there are babies clinging to them.”

In Africa, where the elephant population has plummeted in the last century, more than 110,000 elephants have been slaughtered in the past 10 years alone for their tusks. The elongated incisors are used to make jewelry and piano keys, and items made from ivory have become a status symbol in China, where growing middle and upper classes seek to show off their wealth with luxuries.

In 2019, Chinese businesswoman Yang Felan, dubbed the “Ivory Queen,” was arrested and charged with smuggling $2.5 million worth of tusks from Tanzania to her home country. Yang, “a key link between poachers in East Africa and buyers in China for more than a decade,” was a respected businesswoman, investor, restaurateur and vice chairwoman of the China-Africa Business Council.

“Poachers continue to slaughter elephants and our big cat brothers and sisters,” said Luna Meowson, who tracks the illegal wildlife market for the University of Nappington. “Having extirpated tigers from virtually their entire range, poachers are turning to South America, where jaguar poaching increased 200 fold between 2015 and 2020. It never stops.”

Big Bruce the Lion Slayer — A human hunter poses victoriously after heroically slaying a lion (panthera leo) from atop his trusty steed, a mobility scooter, after a team of guides drove him around the bush in an air-conditioned SUV, then lured the animal directly into his line of sight. A female of the species, presumably his mate, looks on proudly.

Although the earliest details remain murky, fossil records show Homo sapiens first emerged in Africa about 200,000 years ago. The invasive species, which has a gestation period of about nine months, began rapidly breeding and immediately went to war with fellow members of the genus Homo.

After wiping out two-legged rivals including Homo neanderthalensis, Homo altaiensis, Homo denisova and Homo bodoensis, the victorious Homo sapiens set their eyes on other species. Throughout their history they’ve also proven remarkably adept at murdering themselves and continue to hone their skills.

“Those OG humans, they had to really work at slaughtering other species and extirpating wildlife,” said Chonkmatic the Magnificent, King of North American cats. “They didn’t have attack helicopters, stealth bombers, tanks, carrier battle groups, daisy cutters, artillery, mortars, phosphorous, napalm, biological weapons, or even small arms like rifles. In those days a pimply kid from Oklahoma sitting in an air-conditioned base in Virginia couldn’t wipe out an entire city 5,000 miles away by pressing a button ordering a drone to drop a nuke. They had to put some sweat into violence, you know?”

522616 — *Breakthroughs in recent centuries have led to innovative and more convenient ways for Homo sapiens to author mass destruction and render entire sections of the Earth lifeless.*

The species, known for its aptitude for tool-making in addition to eating ultra-processed foods and staring at screens, began with simple tools of destruction like the Mark I Spear, early bows and even torches. Over the centuries they innovated, coming up with clever and inventive new ways to inflict pain and end life until the advent of electricity, the industrial era and the brutally destructive war machines of modern times.

Human scientists have tried to obscure their species’ impact on wildlife and the planet by declaring species like felis catus “invasive” and “alien,” but even if cats are “guilty of grabbing a forbidden snack every now and then,” they don’t have the coordination, technology or will to carve up habitats, render entire swaths of the Earth uninhabitable with nuclear fallout, create Everest-size mountains of garbage, or effortlessly drive millions of species to extinction, Clawin said.

“They’re so good at it, they don’t even have to try,” he noted, pointing out human accidents or incidents of negligence like oil spills and chemical run-off into rivers. “We tend to think of humans out there with shotguns and rifles, cackling maniacally as they shoot anything that moves. And, sure, they do that, especially in places like Texas where the sight of any animal always prompts the question ‘Should we shoot it?’ But our research shows they can wipe out entire categories of fauna in their sleep. It’s remarkable.”
