Drugs have dangerously polluted the world’s rivers, scientists warn

Pharmaceutical pollution poses ‘global threat to human and environmental health’, major study finds

Humanity’s drugs have polluted rivers across the entire world and pose “a global threat to environmental and human health”, according to the most comprehensive study to date.

Pharmaceuticals and other biologically active compounds used by humans are known to harm wildlife and antibiotics in the environment drive up the risk of resistance to the drugs, one of the greatest threats to humanity.

Deluge of dog pee and poo harming nature reserves, study suggests

Urine and faeces creating nitrogen and phosphorus levels that would be illegal on farms, scientists calculate

Dog faeces and urine are being deposited in nature reserves in such quantities that it is likely to be damaging wildlife, according to a new study.

The analysis found that the resulting overfertilisation of the ground with nitrogen and phosphorus by footpaths could reach levels that would be illegal on farmland.

Australians ingest a credit card’s worth of plastic a week – so what’s it doing to us?

Citizen science project mapping microplastics menace in hope of halting spread

Head down to Sydney’s Manly Cove on a weekend, and you might see groups of people crouching diligently on the sand. They’re not searching for shells or bloodworms, but something just as visually striking, not least because it shouldn’t be there: coloured pieces of hard plastic, fragments of polystyrene foam and fibres from fishing line.

For the last three years, a group of volunteers has been surveying the beach each month for microplastics, as part of the Australian Microplastics Assessment Project.

Colloquially known as Ausmap, the citizen science project has collected more than 3.5m pieces of microplastic from more than 300 beaches around the country, ranging from Thursday Island in the north to Bruny Island, off Tasmania’s south-east coast.

How do we solve bitcoin’s carbon problem?

The cryptocurrency consumes more energy than Norway. As countries consider copying China’s ban, experts disagree on whether a greener version is possible

When bitcoin mining company Bit Digital started shipping its energy-intensive computers out of China in early 2021, eyebrows were raised. “A lot of people thought we were being overly paranoid,” says chief strategy officer Sam Tabar, who helped relocate all of the company’s machines to the US and Canada.

But the company’s paranoia paid off. China’s bitcoin mining ban last summer, driven partly by environmental concerns, sent the industry spinning into chaos. The announcement sparked a fire sale of the computers used to power bitcoin, with mining companies scrambling to ship more than 2m of the machines out of China. They arrived by the crateload in countries like the US, Russia and Kazakhstan.

Coral crusaders: Costa Rica’s young divers learn to protect their seas

In Puerto Viejo, scuba diving was once just for tourists, but a centre is training young people with few opportunities to care for the ocean on their doorstep

“I put fresh almond leaves in your underwater masks as anti-fogging – a way to avoid using chemicals. You can remove them once in the water, just before diving,” says Salim Vasquez, 14, pushing her dreadlocks away from her mask.

She distributes the equipment to her fellow divers, who are aged between 14 and 24, and Ana María Arenas, a group coordinator. It is 8am on a cloudy Sunday morning in Puerto Viejo, a Jamaican-inspired city in the south of Costa Rica. The young conservationists are preparing to dive into the Caribbean water for their weekly reef monitoring.

Chemical pollution has passed safe limit for humanity, say scientists

Study calls for cap on production and release as pollution threatens global ecosystems upon which life depends

The cocktail of chemical pollution that pervades the planet now threatens the stability of global ecosystems upon which humanity depends, scientists have said.

Plastics are of particularly high concern, they said, along with 350,000 synthetic chemicals including pesticides, industrial compounds and antibiotics. Plastic pollution is now found from the summit of Mount Everest to the deepest oceans, and some toxic chemicals, such as PCBs, are long-lasting and widespread.

Global heating linked to early birth and damage to babies’ health, scientists find

Exclusive: Studies show high temperatures and air pollution during pregnancy can cause lifelong health effects

The climate crisis is damaging the health of foetuses, babies and infants across the world, six new studies have found.

Scientists discovered increased heat was linked to fast weight gain in babies, which increases the risk of obesity in later life. Higher temperatures were also linked to premature birth, which can have lifelong health effects, and to increased hospital admissions of young children.

‘Babies here are born sick’: are Bolivia’s gold mines poisoning its indigenous people?

The government has been criticised for apparent inaction as evidence mounts that mercury contamination is causing illness in fishing communities

Outside a small brick house shared by four families, Daniela Prada, who is heavily pregnant, gathers guava leaves to make a tea for her two-year-old son.

“My baby gets sick a lot,” she says, boiling a pot of water in her outdoor kitchen. “He always has diarrhoea and last night he had a fever. Most of the time I give him natural medicine.”

In an identical house nearby, town leader Oscar Lurici says fevers are a part of life in Eyiyo Quibo village on the Beni River in northern Bolivia. People of all ages suffer from debilitating head and body aches, bouts of vomiting and diarrhoea, memory loss and tiredness. Some children show signs of cognitive development delays.

Meet Mr Trash Wheel – and the other ingenious tools that eat river plastic

From ‘bubble barriers’ to floating drones, a host of new projects aim to stop plastic pollution before it ever reaches the ocean

The Great Bubble Barrier is just that – a wall of bubbles. It gurgles across the water in a diagonal screen, pushing plastic to one side while allowing fish and other wildlife to pass unharmed.

The technology, created by a Dutch firm and already being used in Amsterdam, is being trialled in the Douro River in Porto, Portugal, as part of the EU-supported Maelstrom (marine litter sustainable removal and management) project.

Microplastics may be linked to inflammatory bowel disease, study finds

People with IBD have 50% more microplastics in their faeces but more research needed to confirm connection

People with inflammatory bowel disease have 50% more microplastics in their faeces, a study has revealed.

Previous research has shown that microplastics can cause intestinal inflammation and other gut problems in laboratory animals, but the research is the first to investigate potential effects on humans. The scientists found 42 microplastic pieces per gram in dried samples from people with IBD and 28 pieces in those from healthy people.

No mountain high enough: study finds plastic in ‘clean’ air

Microplastics from Africa and North America found airborne in French Pyrenees, 2,877 metres above sea level

From Mount Everest to the Mariana Trench, microplastics are everywhere – even high in the Earth’s troposphere where wind speeds allow them to travel vast distances, a new study has found.

Microplastics are tiny fragments – measuring less than 5mm – that come from packaging, clothing, vehicles and other sources and have been detected on land, in water and in the air.

PFAS ‘forever chemicals’ constantly cycle through ground, air and water, study finds

The Stockholm University study highlights the chemicals’ mobility, which has been found in penguin eggs and polar bears

Toxic PFAS “forever chemicals” in the ocean are transported from seawater to air when waves hit the beach and that phenomenon represents a significant source of air pollution, a new study from Stockholm University has found.

The findings, published in Environmental Science & Technology, also partly explain how PFAS get into the atmosphere and eventually precipitation. The study, which collected samples from two Norwegian sites, also concludes that the pollution “may impact large areas of inland Europe and other continents, in addition to coastal areas”.

‘Gushing oil and roaring fires’: 30 years on Kuwait is still scarred by catastrophic pollution

Oilwells set alight by Iraqi forces in 1991 were put out within months, but insidious pollution still mars the desert

For 10 months in Kuwait, everything was upside down. Daytime was full of darkness from the thick smoke, and nights were bright from the distant glow of burning oilwells.

When Iraq’s leader, Saddam Hussein, ordered the occupation of Kuwait in August 1990 in an attempt to gain control of the lucrative oil supply of the Middle East and pay off a huge debt accrued from Kuwait, he was fairly quickly forced into retreat by a US coalition which began an intensive bombing campaign.

‘Disastrous’ plastic use in farming threatens food safety – UN

Food and Agriculture Organization says most plastics are burned, buried or lost after use

The “disastrous” way in which plastic is used in farming across the world is threatening food safety and potentially human health, according to a report from the UN’s Food and Agriculture Organization.

It says soils contain more microplastic pollution than the oceans and that there is “irrefutable” evidence of the need for better management of the millions of tonnes of plastics used in the food and farming system each year.

Nurdles: the worst toxic waste you’ve probably never heard of

Billions of these tiny plastic pellets are floating in the ocean, causing as much damage as oil spills, yet they are still not classified as hazardous

When the X-Press Pearl container ship caught fire and sank in the Indian Ocean in May, Sri Lanka was terrified that the vessel’s 350 tonnes of heavy fuel oil would spill into the ocean, causing an environmental disaster for the country’s pristine coral reefs and fishing industry.

Classified by the UN as Sri Lanka’s “worst maritime disaster”, the biggest impact was not caused by the heavy fuel oil. Nor was it the hazardous chemicals on board, which included nitric acid, caustic soda and methanol. The most “significant” harm, according to the UN, came from the spillage of 87 containers full of lentil-sized plastic pellets: nurdles.

Battery power: five innovations for cleaner, greener electric vehicles

EVs are seen as key in transition to low-carbon economy, but as their human and environmental costs become clearer, can new tech help?

While the journey to a low-carbon economy is well under way, the best route to get there remains up for debate. But, amid the slew of “pathways” and “roadmaps”, one broad consensus exists: “clean” technology will play a vital role.

Nowhere is this truer than for transport. To cut vehicle emissions, an alternative to the combustion engine is required.

Fabrice Monteiro’s best photograph: a spirit emerges from a rubbish dump in Senegal

‘The model is holding a child’s doll, looking out over the wreckage. It represents the future generations we’re condemning to environmental catastrophe’

Outside Dakar, Senegal’s capital, is a rubbish dump with its own name: Mbeubeuss. The land on which it sits was once flat swampland. It began as a landfill site in 1968; today, it is a mountain of rubbish. It has accumulated so much plastic waste from the city that to reach it you have to drive on a road of compacted trash.

This is not the Africa I grew up in. As a child here in the 1970s and 80s, it was not like this. But when I returned in 2012, I was shocked at what I found. Here in Senegal, there was plastic waste everywhere – at roadsides, in trees, everywhere. The younger generation don’t know any different: it’s just part of their environment now. I decided I wanted to shoot a series to raise awareness of environmental issues in Senegal, in the hope that people would realise that things do not have to be this way. I wanted to connect environmental issues with the cultural interests of the population, and started researching animism – the belief that objects and the natural world are imbued with spirits.

‘I can’t see any positives’: return of cruise ships may bring a storm of protest to regional Australian ports

Post-Covid cruising industry wants picturesque towns on its itineraries, while locals fear the pollution and damage the ships can bring

As a teenager, Dylan Boag couldn’t wait to move to the city, but when he finally arrived, all he could think about was getting back home to the pristine waters of Jervis Bay, 200km south of Sydney.

Today the 30-year-old runs an eco-tourism company in the 102sq km-bay with his partner, Lara Hindmarsh.
