“The Earth is what we all have in common”*…
There’s a pervasive notion in our society that nature is something outside, over there, other, from what we are as humans. From religious texts teaching that God provided humans with dominion over Earth, to futuristic literature pitching nature as our past and human ingenuity and technology as our future, the narrative that humans are beyond – or even superior to – nature is deeply entrenched.
This separation, this othering of nature, has arguably enabled our rampant destruction of the rest of the living world, and even led some to claim that our human nature is incompatible with nature itself.
Now a huge international study involving geography, archeology, ecology, and conservation adds to the wealth of sciences that exposes this idea as the lie it is.
Researchers found that for most of our history, humanity has lived in equilibrium with our world, despite us having altered most of Earth’s terrestrial surface far sooner than we realized. “Societies used their landscapes in ways that sustained most of their native biodiversity and even increased their biodiversity, productivity, and resilience,” said University of Maryland environmental systems scientist Erle Ellis.
Analyzing reconstructions of historic global land use by humans and comparing this to global patterns of biodiversity, the researchers found that by 10000 BCE humans had transformed nearly three-quarters of Earth’s land surface – you can view an interactive map of their findings here.
This upends previous models that suggested most land was still uninhabited as recently as 1500 CE. “Lands now characterized as ‘natural’, ‘intact’, and ‘wild’ generally exhibit long histories of human use,” University of Queensland conservation scientist James Watson explained.
…
“There’s a paradigm among natural scientists, conservationists, and policymakers that human transformation of terrestrial nature is mostly recent and inherently destructive,” said Watson.
In recent times, it’s certainly appeared that way, but clearly this hasn’t always been the case – humanity’s presence hasn’t always caused the life around us to wither away. The researchers note that in many areas, mosaics of diverse landscapes managed by people were sustained for millennia.
They used strategies like planting, animal domestication, and managing the ecosystems in a way that made the landscape not just more productive for us, but helping to support high species richness too. “Our study found a close correlation between areas of high biodiversity and areas long occupied by Indigenous and traditional peoples,” said Max Planck Institute archeologist Nicole Boivin.
“The problem is not human use per se, the problem is the kind of land use we see in industrialized societies – characterized by unsustainable agricultural practices and unmitigated extraction and appropriation.”
…
“We need to recognize that some types of human activity – particularly more traditional land management practices that we see in the archaeological record or practiced today by many Indigenous peoples – are actually really supportive of biodiversity. We need to promote and empower that,” said Bovin.
University of Maine anthropologist Darren Ranco noted that while indigenous people manage around 5 percent of the world’s lands that currently contain 80 percent of the world’s biodiversity, they have been excluded from management and access in protected areas like the US National Parks.
These findings make it clear that we need to empower Indigenous, traditional, and local peoples who know their lands in ways science is only just beginning to understand, explained Ellis. While no one is suggesting we revert to technology-less societies of our past, the idea is to learn from different ways of living that have proven track records of longevity.
From there, we can find new and better ways forward with the help of our advanced technologies, and a big part of this is recognizing that we are part of nature just as nature is a part of us.

By way of an illustration of the issue, “Climate crisis has shifted the Earth’s axis, study shows“:
In the past, only natural factors such as ocean currents and the convection of hot rock in the deep Earth contributed to the drifting position of the poles. But the new research shows that since the 1990s, the loss of hundreds of billions of tonnes of ice a year into the oceans resulting from the climate crisis has caused the poles to move in new directions.
Indeed, we’ve moved the poles 4 meters since 1980…

As we find balance, we might spare a thought for Jean Nicot de Villemain; he died on this date in 1604. A diplomat and scholar, he introduced tobacco to the French court (and thus, into wide usage in Europe). In 1560, while serving as ambassador in Portugal, he was shown a tobacco plant in the garden of Lisbon botanist Damião de Goes, who claimed it had healing properties. Nicot applied it to his nose and forehead and found it relieved his headaches.
Nicot sent home seeds and leaves of tobacco, recommending its marvelous therapeutic value. He then sent snuff to Catherine de Medici, the Queen of France to treat her migraine headaches. She was impressed with its results, and became an advocate.
The tobacco plant, Nicotiana tabacum, and its active substance, nicotine, derive their names from his.
Nicot also compiled one of the first French dictionaries, Thresor de la langue françoyse (1606).
“If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us”*…
Countries around the world depend on a range of vital natural services to help maintain the health and stability of their communities and economies. Better known as biodiversity and ecosystem services, these include food provision, water security and regulation of local air quality among others.
These services underpin all economic activity in our societies globally. Assessing biodiversity risks is complex, however, as there is a massive underlying collection of risks. To build understanding of this global issue and foster dialogue around biodiversity, Swiss Re Institute has developed a new Biodiversity and Ecosystem Services (BES) Index.
Swiss Re Institute’s BES Index reveals that over half (55%) of global GDP is dependent on biodiversity and ecosystem services. It also shows that in a fifth of all countries, ecosystems are in a fragile state for more than 30% of the entire country area…

As we recall that this is the only earth we get, we might spare a thought for Margaret Thomas “Mardy” Murie; she died on this date in 2003. Called the “Grandmother of the Conservation Movement” by both the Sierra Club and the Wilderness Society, she helped in the passage of the Wilderness Act, and was instrumental in creating the Arctic National Wildlife Refuge. She was the recipient of the Audubon Medal, the John Muir Award, and the Presidential Medal of Freedom—the highest civilian honor awarded by the United States.

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

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.

As we take the shade, we might spare a thought for Gerald “Gerry” Malcolm Durrell; he died on this date in 1995. A British naturalist, zookeeper, conservationist, author, and television presenter, most of his work was rooted in his life as an animal collector and enthusiast… though he is probably most widely known for his autobiographical book My Family and Other Animals and its successors, Birds, Beasts, and Relatives and The Garden of the Gods... which have been made into television and radio mini-series many times, most recently as ITV’s/PBS’s The Durrells.
“The first problem for all of us, men and women, is not to learn, but to unlearn”*…

In February of 1966, Bobbi Gibb received a letter in her mailbox from the organizers of the Boston Marathon. She expected to find her competition number inside the package. Instead she found herself reading a disqualifying letter. It stated that women are “not physiologically able to run a marathon.” The Amateur Athletics Union prohibited women from running farther than 1.5 miles, and the organizers just couldn’t “take the liability” of having her compete.
Refusing to take no for an answer, two months later the 23-year-old hid in a forsythia bush near the marathon start line. Disguising herself in a hoodie and her brother’s Bermuda shorts, she joined the throng once half the men had already started running. Her identity was soon obvious, but she only received encouragement, spectators yelling, “Way to go, girlie!”
Three hours, 21 minutes, and 40 seconds later, Gibb tore through the finish line ahead of two-thirds of the male competitors…

As we cheer her on, we might send similarly admiring birthday greetings to Jane Morris Goodall; she was born on this date in 1934. A primatologist and anthropologist, her (over 55-year) study of the social and family interactions of wild chimpanzees in Tanzania have made her the world’s foremost expert on chimpanzees.
Born and raised in Kenya, she reached out to the archaeologist and palaeontologist Louis Leakey, who was coincidentally looking for someone to study primate behavior. With his support, she became the eighth person to be allowed to study for a PhD at Cambridge University without first having obtained a BA or BSc– after which, she returned to Africa and her life’s work.
She is the founder of the Jane Goodall Institute and the Roots & Shoots program, and has worked extensively on conservation and animal welfare issues. She has served on the board of the Nonhuman Rights Project since its founding in 1996. In April 2002, she was named a UN Messenger of Peace.
