CNN reports: While the wildfires raging in the Amazon rainforest may constitute an “international crisis,” they are hardly an accident. The vast majority of the fires have been set by loggers and ranchers to clear land for cattle. The practice is on the rise, encouraged by Jair Bolsonaro, Brazil’s populist pro-business president, who is backed by the country’s so-called “beef caucus.” While this may be business as usual for Brazil’s

Fires in the Amazon, the planet at risk
Tierra Curry writes: In Brazil, the Amazon rainforest is now burning at a record rate. The greedy, short-sighted policies of Brazil’s far-right President Jair Bolsonaro are jeopardizing indigenous peoples and countless plants and animals. Indeed, in the midst of a climate emergency, Bolsonaro’s policies to slash environmental protections and develop the Amazon for mining, ranching and farming jeopardize the future of life on Earth as we know it.

Living in space
By Paul Woodward To see things clearly, we often need to break the patterns of habit. The Earth, physically and metaphorically — the ground of human experience — is the stationary foundation that forms the background of movement: our movement across its surface; the terra firma against which the oceans wash and above which birds fly; the horizon that the Sun rises above and then falls beneath. Intellectually, as

Nations gather to tackle the world’s sixth mass extinction
The Guardian reports: From giraffes to sharks, the world’s endangered species could gain better protection at an international wildlife conference. The triennial summit of Convention on International Trade in Endangered Species (Cites), that began on Saturday, will tackle disputes over the conservation of great beasts such as elephants and rhinos, as well as cracking down on the exploitation of unheralded but vital species such as sea cucumbers, which clean ocean

It’s raining plastic: Microscopic fibers fall from the sky in the Rocky Mountains
The Guardian reports: Plastic was the furthest thing from Gregory Wetherbee’s mind when he began analyzing rainwater samples collected from the Rocky Mountains. “I guess I expected to see mostly soil and mineral particles,” said the US Geological Survey researcher. Instead, he found multicolored microscopic plastic fibers. The discovery, published in a recent study (pdf) titled “It is raining plastic”, raises new questions about the amount of plastic waste permeating

A quarter of humanity faces looming water crises
The New York Times reports: Countries that are home to one-fourth of Earth’s population face an increasingly urgent risk: The prospect of running out of water. From India to Iran to Botswana, 17 countries around the world are currently under extremely high water stress, meaning they are using almost all the water they have, according to new World Resources Institute data published Tuesday. Many are arid countries to begin with;

We must change food production to save the world, says leaked report
The Guardian reports: Attempts to solve the climate crisis by cutting carbon emissions from only cars, factories and power plants are doomed to failure, scientists will warn this week. A leaked draft of a report on climate change and land use, which is now being debated in Geneva by the Intergovernmental Panel on Climate Change (IPCC), states that it will be impossible to keep global temperatures at safe levels unless

‘Nature is declining at rates unprecedented in human history,’ says director of biodiversity conservation group
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

The terrifying sound of a human voice
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

Research on honeybees hit by Trump budget cuts
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

Orangutans: Palm oil industry still threatens the lives and habitat of ‘people of the forest’
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

The search for extraterrestrial technology finds none
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

We are more rational than we are told
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

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

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