The prevailing belief in a separation between humans and everything else is an essential function of a contemporary global economy which has permitted unprecedented levels of unsustainable resource extraction. The increasingly complex challenges human beings face in relation to the non-human world call for a paradigm shift: it is becoming ever more urgent to embrace new stories about ourselves and our relation to each other. This is the aim of ‘Stories on Earth’, Failed Architecture’s project for the parallel program of the Dutch Pavilion for the Venice Biennale 2021. Stories on Earth is an experiment which brings together spatial designers and writers to devise new spatial narratives that accommodate the inherent interrelationship between humans and the non-human. We selected three designers whose works challenge humans’ relationship with nature, and three writers with personal and professional connections with Caribbean storytelling…

Six designers and writers participating in FA’s project for Venice Biennale 2021 speak with one composite voice about nature, humanity, and storytelling at: “Stories on Earth: A Collective Voice for the Human and Non-Human.”

On this same topic, check in with musician and humanitarian Peter Gabriel, ecologist Carl Safina, technologist and novelist Jonathan Ledgard, prominent author and speaker on animal behaviour, Temple Grandin, and others…

We are pleased to announce the Interspecies Conversations Public Event 2020 in collaboration with the Coller Foundation, Google and MIT’s Center for Bits and Atoms. We would be delighted if you could join us and contribute to the conversation!

Interspecies I/O’s mission is to encourage, explore and facilitate interfaces for interspecies communication and approaches for deciphering the communication of non-human animals. With the aim to positively impact species conservation, welfare, empathy, compassion, enrichment, sustainability and understanding. It brings together a multidisciplinary group drawn from the sciences, arts and humanities in a rich collaborative forum, to advance the understanding and appreciation of the mental lives and intelligence of the diverse species with which we share our planet…

… at “Interspecies Conversations Public Conference 2020.”

And to complete the hat-trick, Matt Webb’s “On speaking with dolphins.”

As we “Talk to the Animals,” we might recall that it was on this date in 1983 that the first “test-tube baboon” was born; as The New York Times reported

A female black baboon, believed to be the first nonhuman primate conceived in a laboratory dish, has been born at the Southwest Foundation for Research and Education in San Antonio. The baby, named E. T., for embryo transfer, was born July 25, six months after its ”test-tube” fertilization and, coincidentally, on the fifth birthday of Louise Brown, the first human conceived ”in vitro.”…

“Round and round they went with their snakes, snakily”*…

 

Python

 

If pythons are the snake that ate the Everglades, the apocryphal legend of their takeover begins with an appropriately cinematic opening scene. In 1992, Hurricane Andrew plowed into the state, killing 65 people and leveling thousands of homes, as well as—so the story goes—a Burmese python breeding facility.

The reality of their introduction to the area may be less exciting. “The scientific thinking, I believe, is that they were probably animals that were discarded by pet owners deep down into the Everglades,” said Steve Johnson, an associate professor of wildlife ecology and conservation at the University of Florida.

The population of Burmese pythons in the Everglades is impossible to measure with much accuracy. Since the first reported sighting of one in the wild in Florida in 1979, their numbers have exploded. Estimates from the USGS indicate there could be tens of thousands to hundreds of thousands of them in South Florida. Regardless of their actual population size, their impact is clear: pythons have decimated biodiversity in the area. The hungry snakes will consume almost any animal in their path. They seize their prey using sharp, rear-facing fangs that are long enough to pierce a hunter’s arm. Then the snake coils around its victim, constricting the animal until it’s dead. Some hunters, to protect their lower legs from bites, wear camouflage-patterned snake gaiters, light armor that’s similar to shin guards worn by soccer players. But most go without, preferring intuition and quick reflexes over adding another layer of clothing to sweat through in the muggy glades.

To stem the tide of invasive species from the exotic-pet trade, the FWC holds amnesty days that allow pet owners to surrender animals to the agency without penalty. Although most pets that get released into the glades don’t survive, some outlier species like the Burmese python become established in their new ecosystems.

In this case, “established” sounds like an understatement. Pythons have taken over. Everything else has become prey. Since 2003, rabbit populations have disappeared from USGS study areas. Foxes, raccoons, possums, bobcats, and other species are all but gone. Pythons devoured the mammals and have moved on to birds, other reptiles, and possibly fish. The snakes can bring down animals as large as deer—which can either struggle and tear themselves away or become dinner—and even alligators.

Scientists have long suspected that pythons were consuming whole populations of small mammals in the Everglades and have made efforts at estimating the impacts. But exact population counts are impossible in such a vast wilderness. In a 2015 study led by Robert McCleery at the University of Florida, researchers translocated marsh rabbits into an area of the Everglades inhabited by a large number of pythons. At first the rabbits survived. Then temperatures began to rise, and with the warming weather, pythons slithered out of hiding and began to feast. In one year, they had eaten 77 percent of the rabbits…

Pythons are devouring native animal life in the unique ecosystem of South Florida. To help solve the problem, Florida Fish and Wildlife officials have turned to amateur and professional hunters to round up the reptiles in a wild competition called the Python Bowl: “The Misunderstood Python Hunters Saving the Everglades.”

As we ruminate on reptiles, we might recall that it was on this date in 1780 that a combination of thick smoke, fog, and heavy cloud cover caused so complete a darkness to fall on Eastern Canada and the New England area of the United States that candles were needed at noon.  The drear, known as “New England’s Dark Day,” did not disburse until the following evening.

Alt Right, Neo Nazis hold torch rally at UVA

 

When members of the Unite the Right rally marched through Charlottesville on August 11, 2017 in polo shirts and carrying tiki torches, Twitter went wild with jokes. “When you have to use a Polynesian cultural product (tiki torches) to defend and assert white supremacy,” wrote one Twitter pundit. Another captioned a photo of the marchers: “Y’all, we can’t get dates on Friday night (again) so we’re fixin’ to pick up some tiki torches at Walmart & have a klan rally. Who’s in?”

But Sarah Bond, an associate professor of classics at the University of Iowa, didn’t find the jokes funny. “Something horrible is going to happen,” she remembered thinking.

For the past several years, Bond has written about “classical reception” — or how Greco-Roman culture is received and interpreted — for Forbes online, the art and culture website Hyperallergic, and Eidolon, an informal online journal devoted to the classics. Because classical thinkers, institutions, writings, and art have been portrayed as the epitome of “civilization” since the Renaissance, she’s also documented how hate groups have latched onto the perceived legitimacy of antiquity to make themselves seem more legitimate.

“Torches are very much tied to violence in antiquity,” she says. “They are meant to intimidate people. There are a number of examples from antiquity of the use of mob violence where fire and torches are specifically used prior to an assassination.” The Ku Klux Klan, the Nazis, and the Golden Dawn all marched with flames.

The day after the August rally and the Twitter jokes, violence erupted between the marchers and counter-protestors, and alt-right supporter Alex Fields Jr. drove his car into a crowd of anti-racism demonstrators, killing 32-year-old Heather Heyer and injuring dozens of others. Bond, a Virginia native who’d attended undergrad at the University of Virginia in Charlottesville, was upset but not surprised. “That was the tipping point where I was like, you know what? Fuck their use of antiquity.”

White supremacists, misogynists, and anti-Semites see the ancient Mediterranean as a touchstone. Would a better sense of history change their minds? “Hate Groups Love Ancient Greece and Rome. Scholars Are Pushing Back.”

As we correct our corollaries, we might send cooperative birthday greetings to zoologist Warder Clyde Allee; he was born on this date in 1885.  One of the great pioneers of American ecology, Allee is best remembered for his research on animal behavior, protocooperation— for which he’s considered by many to be the “Father of Animal Ecology”– and for identifying what is now known as “the Allee effect“: a positive correlation between population density and the per capita population growth rate in very small populations, the product of cooperation– of the organisms acting as a group as opposed to individually.

Judging by the popularity of the Jurassic Park franchise—five feature films, with a sixth blockbuster scheduled for 2021, three “Lego” Jurassic Park shorts, various theme-park attractions, some forty-six theme-related video games, even a Jurassic Park Crunch Yogurt—dinosaurs (once the province of paleontologists and children) have had a stranglehold on our collective imagination for more than a quarter century. Michael Crichton’s 1990 novel sold more than nine million copies; three years later, the first mega-film, directed by Steven Spielberg, became the second highest-grossing film of all time, earning over $1 billion worldwide.

Though less enormous, less voracious, and lacking dramatic soundtracks to pave their entrances and exits, formidable flesh-and-blood, non-animatronic prehistorics do actually walk among us.

Alligators have been around for some 200 million years, which is 135 million years longer than their dino contemporaries. It wasn’t until the twentieth century that that extraordinary longevity was threatened. Pretty impressive, given all the environmental changes that have ensued in the interim, and the fact that their brains are about the size of a walnut…

Biologically, Crocodilia (alligators, crocodiles, caimans, gharials) are closer to birds, dinosaurs to snakes and lizards, but they share a common ancestry. Fossils reveal that back in the day, some alligators grew to nearly forty feet in length, weighing in at 8.5 tons. Simply put, Crocodilia are the closest living examples of the Jurassic’s ancient denizens.

“Dinosaurs and man, two species separated by 65 million years of evolution, have just been suddenly thrown back into the mix together,” notes Jeff Goldblum’s character, Alan Grant, in the 1993 film. “How can we possibly have the slightest idea what to expect?”

In the case of their alligator cousins, it wasn’t just suddenly. Throughout the American south, they’ve always been pretty much unavoidable.

On the big screen, our relationship to Crichton’s creatures is set and predictable. We enjoy the terror they inspire from the dark safety of our upholstered seats. Alligators, in cinema, have always been as dependable in their villainy as Nazis. What better way to dispose of pesky early Christians or enemy Russian spies?

In the real world, the relationship of humans to ancient apex predators is far more complex

As we ruminate on the reptilian, we might spare a thought for Warder Clyde Allee; he died on this date in 1955.  A zoologist and ecologist who researched the social behavior, aggregations, and distribution of both land and sea animals, he discovered that cooperation is both beneficial and essential in nature. The “Allee effect,” as it came to be known, describes the positive correlation between population density and individual fitness of a population or species.  While his findings are in tension with those of another  another ecologist, George C. Williams who stressed the importance of individual selection, Allee’s emphasis on groups and cooperation remains influential.

“Climate change isn’t an “issue” to add to the list of things to worry about, next to health care and taxes. It is a civilizational wake-up call.”*…

 

climatechange

“Whitening” the ocean (to reflect more solar radiation) by widely dispersing films, foams, floating chips, or other reflectors– or by towing icebergs from the Arctic down to lower latitudes, so the whiteness of the ice would reflect the sun.

 

The 1990s were a critical decade for action on climate change, as world governments prepared to finalize the Kyoto Protocol, an agreement by 37 countries to limit greenhouse-gas emissions. They were also a decade when oil companies poured millions of dollars into government lobbying and public relations, trying to persuade the world there was little to worry about. In 1997, with the Kyoto accord almost complete, Mobil, the major American oil company, published an advertisement in the New York Times and the Washington Post: “Let’s face it: The science of climate change is too uncertain to mandate a plan of action that could plunge economies into turmoil,” it said. “Scientists cannot predict with certainty if temperatures will increase, by how much and where changes will occur.” Around the same time, Exxon CEO Lee Raymond argued in a speech to the World Petroleum Congress that “the case for so-called global warming is far from airtight.” (In 1998, Exxon and Mobil would join in a $73.7 billion deal, the largest corporate merger in the world at the time.)

Recent reporting by the Los Angeles Times and others revealed, however, that Exxon’s rhetoric ran counter to its own internal conclusions about the risks of climate change, as the company reengineered oil platforms and pipelines to account for the rising sea levels that both top executives and the publicity department claimed didn’t exist. Today, even as Exxon endorses the scientific consensus on climate change, supports emissions limits, and even backs some form of carbon taxation, the company exudes a vague optimism, regarding the climate problem as something they can build their way out of…

Perhaps our best guess at the kind of solutions Exxon may have in mind can be found in an obscure 1997 study on the topic of geoengineering. During the peak of Exxon’s obfuscation, the company’s top climate scientists, Brian Flannery and Haroon Kheshgi, along with two other scientists who didn’t work for Exxon, coauthored a chapter in a book called Engineering Response to Global Climate Change. Using dense, technical language, they outlined more than a dozen planetary-scale fixes to global warming. Not every idea was their own—some were borrowed, at least partially, from prior scientific literature—and the scientists also cautioned that the proposed solutions were not necessarily ready to be implemented. “Geoengineering may well have unintended and unforeseen consequences,” they wrote.

Indeed, geoengineering was considered fringe science in the 1990s, not least because there was still widespread hope that carbon emissions could be reduced through global agreements like Kyoto. (President George W. Bush withdrew the United States from the accord in 2001.) It would take a decade before Scientific American declared that climate intervention had “gained respectability,” and almost 15 years until the United Nations’ climate-research body, the Intergovernmental Panel on Climate Change, would begin publishing assessments on geoengineering options. That’s because while some of the ideas featured in the Exxon study were straightforward (planting trees, for example), a lot of them were quite insane…

As we head for the hills, we might spare a thought for Robert McCorkle Netting; he died on this date in 1995.  A geographer and anthropologist, he pioneered the field of cultural ecology.  Among the many findings from his extensive field work, he argued that worldwide, small farms succeeded where large-scale agricultural enterprises tended to fail, the household being the most effective management unit.  His methodology has been widely adopted, and his textbook, Cultural Ecology, is widely used.
