The Guardian reports: From the tops of trees to the depths of the oceans, humanity’s destruction of wildlife is continuing to drive many species towards extinction, with the latest “red list” showing a third of all species assessed are threatened. The razing of habitat and hunting for bushmeat has now driven seven primates into decline, while overfishing has pushed two families of extraordinary rays to the brink. Pollution, dams and over-abstraction of freshwater are responsible for serious declines in river…

Ed Yong writes: In the summer of 2017, the mountain lions, bobcats, and other residents of the Santa Cruz Mountains were treated to the dulcet tones of the ecologist Justin Suraci and his friends, reading poetry. Some of the animals became jittery. Others stopped eating. A few fled in fear. Suraci, who’s based at the University of California at Santa Cruz, wasn’t there to see their reactions. He and his colleagues had strung up a set of speakers that would…

Research on honeybees hit by Trump budget cuts

Research on honeybees hit by Trump budget cuts

Comments 0 Comment

CNN reports: The US Department of Agriculture has suspended data collection for its annual Honey Bee Colonies report, citing cost cuts — a move that robs researchers and the honeybee industry of a critical tool for understanding honeybee population declines, and comes as the USDA is curtailing other research programs. It’s also another step toward undoing President Barack Obama’s government-wide focus on protecting pollinators, including bees and butterflies, whose populations have plummeted in recent years.

The New York Times reports: The men came at Hope and her baby with spears and guns. But she would not leave. There was no place for her to go. When the air-gun pellets pierced Hope’s eyes, blinding her, she felt her way up the tree trunks, auburn-furred fingers searching out tropical fruit for sustenance. By the end, Hope’s torso was slashed with deep lacerations. Multiple bones were broken. Seventy-four pellets were lodged in her body. Her months-old baby had…

The Guardian reports: The close encounter will have to wait. Astronomers have come up empty-handed after scanning the heavens for signs of intelligent life in the most extensive search ever performed. Researchers used ground-based telescopes to eavesdrop on 1,327 stars within 160 light years of Earth. During three years of observations they found no evidence of signals that could plausibly come from an alien civilisation. The only signals picked up by the Green Bank telescope in West Virginia and the…

Steven Poole writes: Humanity’s achievements and its self-perception are today at curious odds. We can put autonomous robots on Mars and genetically engineer malarial mosquitoes to be sterile, yet the news from popular psychology, neuroscience, economics and other fields is that we are not as rational as we like to assume. We are prey to a dismaying variety of hard-wired errors. We prefer winning to being right. At best, so the story goes, our faculty of reason is at constant…

‘Hell on Earth’ scenario predicted if climate crisis doesn’t trigger immediate drastic action

‘Hell on Earth’ scenario predicted if climate crisis doesn’t trigger immediate drastic action

Comments 0 Comment

Al Jazeera reports: A climate change paper grabbed headlines this week with its terrifying prediction of what the world will be in 30 years’ time – absent drastic and immediate change to human societies. “World of outright chaos,” “Climate apocalypse,” “We’re all gonna die,” the media banners blared. The sobering headlines and equally disconcerting stories beneath described a “scenario analysis” by an Australian think-tank, Breakthrough National Center for Climate Restoration. The paper portrayed what the year 2050 will look like…

People eat at least 50,000 plastic particles a year, study finds

Comments 0 Comment

The Guardian reports: The average person eats at least 50,000 particles of microplastic a year and breathes in a similar quantity, according to the first study to estimate human ingestion of plastic pollution. The true number is likely to be many times higher, as only a small number of foods and drinks have been analysed for plastic contamination. The scientists reported that drinking a lot of bottled water drastically increased the particles consumed. The health impacts of ingesting microplastic are…

Influential panel votes to recognize Earth’s new epoch: The Anthropocene

Comments 0 Comment

Nature reports: A panel of scientists voted this week to designate a new geologic epoch — the Anthropocene — to mark the profound ways in which humans have altered the planet. That decision, by the 34-member Anthropocene Working Group (AWG), marks an important step towards formally defining a new slice of the geologic record — an idea that has generated intense debate within the scientific community over the past few years. The panel plans to submit a formal proposal for…

Philip Ball writes: Who said this? “I’ve been having to say everywhere I go that there is no planet B, there is no escape hatch, there is no second Earth; this is the only planet we have.” If you’re a science fiction fan the answer might surprise you: it was the writer Kim Stanley Robinson, whose Mars trilogy is an ultimately utopian series of tales that describe the terraforming of Mars – planetary engineering to give it an Earth-like environment…

Humans are killing off most large wild animals as sixth mass extinction advances

The Guardian reports: Humanity’s ongoing destruction of wildlife will lead to a shrinking of nature, with the average body size of animals falling by a quarter, a study predicts. The researchers estimate that more than 1,000 larger species of mammals and birds will go extinct in the next century, from rhinos to eagles. They say this could lead to the collapse of ecosystems that humans rely on for food and clean water. Humans have wiped out most large creatures from…

The New York Times reports: Humans are transforming Earth’s natural landscapes so dramatically that as many as one million plant and animal species are now at risk of extinction, posing a dire threat to ecosystems that people all over the world depend on for their survival, a sweeping new United Nations assessment has concluded. The 1,500-page report, compiled by hundreds of international experts and based on thousands of scientific studies, is the most exhaustive look yet at the decline in…

Another recalled his experiences just last year in Cape Town – one of the world’s most attractive tourism and leisure destinations – when more than 2 million people faced the nightmare prospect of all taps, in every home and…

The Guardian reports: The world’s leading scientists will warn the planet’s life-support systems are approaching a danger zone for humanity when they release the results of the most comprehensive study of life on Earth ever undertaken. Up to 1m species are at risk of annihilation, many within decades, according to a leaked draft of the global assessment report, which has been compiled over three years by the UN’s leading research body on nature. The 1,800-page study will show people living…

Tom Chatfield writes: Plenty of creatures can communicate richly, comprehend one another’s intentions and put tools to intelligent and creative use: cetaceans, cephalopods, corvids. Some can even develop and pass on particular local practices: New Caledonian crows, for example, exhibit a “culture” of tool usage, creating distinct varieties of simple hooked tools from plants in order to help them feed. Only humans, however, have turned this craft into something unprecedented: a cumulative process of experiment and recombination that over mere…

  New Zealand PM, Jacinda Ardern, said: To the global community who have joined us today, who reached out to embrace New Zealand, and our Muslim community, to all of those who have gathered here today, we say thank you. And we also ask that the condemnation of violence and terrorism turns now to a collective response. The world has been stuck in a vicious cycle of extremism breeding extremism and it must end. We cannot confront these issues alone,…
