Humanity is a tiny fraction of life on Earth but has destroyed over 80% of wild mammals and half of plants

The Guardian reports: Humankind is revealed as simultaneously insignificant and utterly dominant in the grand scheme of life on Earth by a groundbreaking new assessment of all life on the planet. The world’s 7.6 billion people represent just 0.01% of all living things, according to the study. Yet since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds. The new work is the first…

More than 95% of world’s population breathe dangerous air, major study finds

Comments 0 Comment

The Guardian reports: More than 95% of the world’s population breathe unsafe air and the burden is falling hardest on the poorest communities, with the gap between the most polluted and least polluted countries rising rapidly, a comprehensive study of global air pollution has found. Cities are home to an increasing majority of the world’s people, exposing billions to unsafe air, particularly in developing countries, but in rural areas the risk of indoor air pollution is often caused by burning…

  Elizabeth Kolbert writes: In the first half of the 19th century, one of America’s most prominent scientists was a doctor named Samuel Morton. Morton lived in Philadelphia, and he collected skulls. He wasn’t choosy about his suppliers. He accepted skulls scavenged from battlefields and snatched from catacombs. One of his most famous craniums belonged to an Irishman who’d been sent as a convict to Tasmania (and ultimately hanged for killing and eating other convicts). With each skull Morton performed…

Land degradation by human activities pushing Earth into sixth mass extinction and undermining well-being of 3.2 billion people

Land degradation by human activities pushing Earth into sixth mass extinction and undermining well-being of 3.2 billion people

  Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES): Worsening land degradation caused by human activities is undermining the well-being of two fifths of humanity, driving species extinctions and intensifying climate change. It is also a major contributor to mass human migration and increased conflict, according to the world’s first comprehensive evidence-based assessment of land degradation and restoration. The dangers of land degradation, which cost the equivalent of about 10% of the world’s annual gross product in 2010 through…

The Washington Post reports: Seventy-nine thousand tons of plastic debris, in the form of 1.8 trillion pieces, now occupy an area three times the size of France in the Pacific Ocean between California and Hawaii, a scientific team reported on Thursday. The amount of plastic found in this area, known as the Great Pacific Garbage Patch, is “increasing exponentially,” according to the surveyors, who used two planes and 18 boats to assess the ocean pollution. “We wanted to have a…

Sudan, the last male northern white rhinoceros, dies in Kenya

Comments 0 Comment

The New York Times reports: The last male northern white rhinoceros died on Monday at the Ol Pejeta Conservancy in Kenya following a series of infections and other health problems. At 45, Sudan was an elderly rhino, and his death was not unexpected. Hunted to near-extinction, just two northern white rhinos now remain: Najin, Sudan’s daughter, and Fatu, his granddaughter, both at the conservancy. The prospect of losing the charismatic animals has prompted an unusual scientific effort to develop new…

After a volcano’s ancient supereruption, humanity may have thrived

After a volcano’s ancient supereruption, humanity may have thrived

Shannon Hall writes: The Toba supereruption [about 74,000 years ago] expelled roughly 10,000 times more rock and ash than the 1980 Mount St. Helens eruption. So much ejecta would have darkened skies worldwide, causing scientists to speculate that it might have plunged the Earth into a volcanic winter whose chill could be felt far from Indonesia. Climate models suggest that temperatures may have plummeted by as much as 30 degrees Fahrenheit. And in such a cold world, plants may have…

Women in Iran are pulling off their headscarves — and hoping for a ‘turning point’

Women in Iran are pulling off their headscarves — and hoping for a ‘turning point’

Comments 0 Comment

The Washington Post reports: Iranian women have been raising a new challenge to their Islamic government, breaking one of its most fundamental rules by pulling off their headscarves in some of the busiest public squares and brandishing them in protest. While these guerrilla protesters number only in the dozens, Iran’s government has taken notice of their audacity. On Thursday, planned demonstrations to coincide with International Women’s Day were preempted by a heavy police presence on the streets of the capital,…

David Graeber and David Wengrow write: Stonehenge, it turns out, was only the latest in a very long sequence of ritual structures, erected in timber as well as stone, as people converged on the plain from remote corners of the British Isles, at significant times of year. Careful excavation has shown that many of these structures – now plausibly interpreted as monuments to the progenitors of powerful Neolithic dynasties – were dismantled just a few generations after their construction. Still…

G. M. Tamás writes: Yes, of course, we are all indignant and horrified and incredulous and ashamed: the death and decomposition of the international state system causes mayhem and suffering that defies reason and imagination. Everybody has seen the wordless statement of UNICEF: they could not find words to express what they have seen and what they have felt. Various ethnic and political groups in Syria are killing each other and they are also killed by the states of Turkey,…

Conservation efforts are failing to address the importance of preserving intact forests

Conservation efforts are failing to address the importance of preserving intact forests

Comments 0 Comment

Morgan Erickson-Davis reports: When it comes to habitat quality and ecosystem services, research has shown that natural landscapes do it best. A new study, published recently in Nature, adds fodder to this argument, describing how intact forests are critically important for mitigating climate change, maintaining water supplies, safeguarding biodiversity, and even protecting human health. However, it warns that global policies aimed at reducing deforestation are not putting enough emphasis on the preservation of the world’s dwindling intact forests, instead relying…

By Dana J. Graef High in the Ecuadorian Andes, the peak of Cotacachi was once reliably white. But by the early 2000s, the glacier on top of this dormant volcano, which reaches more than 16,200 feet, had disappeared. This made it—as anthropologist Robert E. Rhoades and his co-authors Xavier Zapata Ríos and Jenny Aragundy Ochoa wrote in the 2008 book Darkening Peaks—one of “the first Andean mountains in the past half-century to completely lose its glacier as a result of…

The universal sign for ‘Look over there!’ isn’t so common in some cultures. Helena Ohman/Shutterstock.com By Kensy Cooperrider, University of Chicago Octopuses have long arms and plenty of smarts, but they don’t point. Nor do chimps, gorillas or other apes, at least not in the wild. Humans, on the other hand, are prodigious pointers. Infants use the gesture before they can talk, often around 1 year of age. By 2, they’ll waddle around, their forefingers sweeping over the world like…

New mapping shows just how much fishing impacts the world’s seas

New mapping shows just how much fishing impacts the world’s seas

Comments 0 Comment

Science News reports: Fishing has left a hefty footprint on Earth. Oceans cover more than two-thirds of the planet’s surface, and industrial fishing occurred across 55 percent of that ocean area in 2016, researchers report in the Feb. 23 Science. In comparison, only 34 percent of Earth’s land area is used for agriculture or grazing. Previous efforts to quantify global fishing have relied on a hodgepodge of scant data culled from electronic monitoring systems on some vessels, logbooks and onboard…

One of the defining characteristics of life is movement, be that in the form of locomotion or simply growth. What is inanimate is not alive and yet humans, through the use of technology, are constantly seeking ways to reduce the need to move our own limbs. We have set ourselves on a trajectory that, if taken to its logical conclusion, will eliminate our need to possess a fully functioning body as we reduce ourselves to a corpse-like condition sustained by…

Mark O’Connell writes: Early last summer, just as my interests in the topics of civilisational collapse and Peter Thiel were beginning to converge into a single obsession, I received out of the blue an email from a New Zealand art critic named Anthony Byrt. If I wanted to understand the extreme ideology that underpinned Thiel’s attraction to New Zealand, he insisted, I needed to understand an obscure libertarian manifesto called The Sovereign Individual: How to Survive and Thrive During the…
