Dozens of Canada’s First Nations lack drinking water: ‘Unacceptable in a country so rich’

Posted on by

Indigenous leaders are suing the Canadian government for not providing clean water – and ministers admit they have failed

Curve Lake First Nation, a forested community in southern Canada, is surrounded on three sides by fresh water.

But for decades, residents have been unable to safely make use of it. Wary of crumbling infrastructure and waterborne illness, the community instead relies on shipments of bottled water. The community’s newly elected chief, aged 34, has lived her whole life without the guarantee of clean water flowing from the tap.

Stinging wasps are precious, not pointless, say scientists

Much-hated insects are voracious predators of pests, produce powerful antibiotics and pollinate plants

For those who have asked what the point of wasps is, there is now a comprehensive answer. They are voracious predators of pest insects, produce powerful antibiotics in their venom, pollinate plants and even make a nutritious snack.

The benefits to humans of the much-hated insects are revealed in the first major scientific review of the ecosystem services they provide. It focused on the 33,000 known species of hunting wasps, which carry stings and live in every corner of the world.

Impact is on par with adult punch and larvae can move fast enough to capture prey, researchers observed

There’s a small, iridescent crustacean you might have heard of: its powerful punch can crack holes in aquarium glass and be deployed at the speed of a bullet. These aggressive critters – called mantis shrimp – can also be trigger happy, keen to pummel prey, predators and even their own kind if the need arises.

So how old do offspring have to be to unleash blows? Pretty young it turns out. Mantis shrimp larvae can bludgeon their dinner nine to 15 days after hatching, researchers have found.

Killer farm robot dispatches weeds with electric bolts

Makers say machine could be part of an agricultural revolution of automation and sustainability

In a sunny field in Hampshire, a killer robot is on the prowl. Once its artificial intelligence engine has locked on to its target, a black electrode descends and delivers an 8,000-volt blast. A crackle, a puff of smoke, and the target is dead – a weed, boiled alive from the inside.

It is part of a fourth agricultural revolution, its makers say, bringing automation and big data into farming to produce more while harming the environment less. Pressure to cut pesticide use and increasing resistance to the chemicals meant killing weeds was the top priority for the farmers advising the robot company.

Life finds a way: in search of England’s lost, forgotten rainforests

Posted on by

Much of Britain’s temperate rainforest has been destroyed – but it can sometimes regenerate. The race is on to map what survives and restore what we can

Few people realise that England has fragments of a globally rare habitat: temperate rainforest. I didn’t really believe it until I moved to Devon last year and started visiting some of these incredible habitats. Temperate rainforests are exuberant with life. One of their defining characteristics is the presence of epiphytes, plants that grow on other plants, often in such damp and rainy places. In woods around the edge of Dartmoor, in lost valleys and steep-sided gorges, I’ve spotted branches dripping with mosses, festooned with lichens, liverworts and polypody ferns.

You may have heard of England’s most famous fragment of temperate rainforest: Wistman’s Wood, in the middle of Dartmoor. With its gnarled and stunted oaks, its remote location marooned within a sheep-nibbled moorscape, and attendant tales of spectral hounds that inspired Sir Arthur Conan Doyle’s The Hound of the Baskervilles, it has an outsize reputation for somewhere so tiny in size: eight acres – about four football pitches.

Electric vehicles on world’s roads expected to increase to 145m by 2030

Posted on by

Under existing climate policies, electric vehicles could wipe out use of 2m barrels a day of diesel and petrol

The number of electric cars, vans, trucks and buses on the world’s roads is on course to increase from 11m vehicles to 145m by the end of the decade, which could wipe out demand for millions of barrels of oil every day.

A report by the International Energy Agency has found that there could be 230m electric vehicles worldwide by 2030 if governments agreed to encourage the production of enough low-carbon vehicles to stay within global climate targets.

Scale of aid cut emerges in leaked FCDO memo, prompting experts to describe it as ‘a national shame’

The UK is to slash funding for lifesaving water, sanitation and hygiene projects in developing nations by more than 80%, according to a leaked memo.

The cuts have been described as “savage”, “incredible” and “a national shame” by experts highlighting that sanitation and handwashing is a key line of defence during the coronavirus pandemic. The reduction to the bilateral aid budget was revealed as details emerged of cuts in the foreign aid budget.

Scientists find way to remove polluting microplastics with bacteria

Posted on by

Sticky property of bacteria used to create microbe nets that can capture microplastics in water to form a recyclable blob

Microbiologists have devised a sustainable way to remove polluting microplastics from the environment – and they want to use bacteria to do the job.

Bacteria naturally tend to group together and stick to surfaces, and this creates an adhesive substance called “biofilm” – we see it every morning when brushing our teeth and getting rid of dental plaque, for example. Researchers at the Hong Kong Polytechnic University (PolyU) want to use this sticky bacteria property and create tape-like microbe nets that can capture microplastics in polluted water to form an easily disposable and recyclable blob.

Powering Past Coal Alliance accused of failing to follow up on pledges as many countries expand use of coal

An attempt by the UK government to encourage countries and businesses around the world to quit coal for power generation is failing to make an impact, and in danger of being used as “greenwash”, an assessment has found.

The Powering Past Coal Alliance, led by the UK and Canada, with 111 members including 24 governments, local governments and businesses, is a key plank of Boris Johnson’s strategy for vital UN climate talks to be hosted in Glasgow in November.

Chemicals and plastics, not just overfishing, threaten aquatic food chain with ‘disaster’, report warns


Increasing chemical and plastic pollution are “significant” contributors to the decline of fish and other aquatic organisms, yet their impact is being missed by regulators, according to a report by environmentalists.

The report, Aquatic Pollutants in Oceans and Fisheries, by the International Pollutants Elimination Network and the National Toxics Network, draws together scientific research on how pollution is adversely affecting the aquatic food chain. It catalogues the “serious impacts” of “invisible killers” such as persistent organic pollutants and excessive nutrients on the immunity, fertility, development and survivaL of aquatic animals.

Rich countries urged to stump up to help developing nations cut greenhouse gas emissions

Boris Johnson must push rich countries meeting in Cornwall in June to come up with tens of billions of dollars more in aid for poor countries to deal with climate breakdown, or face the failure of vital UN climate talks to be hosted by the UK in Glasgow in November, according to leading climate experts.

The UK holds the presidency this year both of the annual meeting of the G7 group of the world’s economic superpowers, and of the Cop26 climate summit.

If it’s safe, dump it in Tokyo. We in the Pacific don’t want Japan’s nuclear wastewater | Joey Tau and Talei Luscia Mangioni

Japan’s plans to discharge radioactive wastewater into the Pacific Ocean is a callous act that would do catastrophic harm

Earlier this month, the Japanese government announced plans to discharge 1m tonnes of radioactive wastewater accruing since the Fukushima Daiichi nuclear disaster in 2011 into the Pacific Ocean.

To Pacific peoples, who have carried the disproportionate human cost of nuclearism in our region, this is yet another act of catastrophic and irreversible trans-boundary harm that our region has not consented to.

Why parents are choosing to rent their kids’ clothes

The secondhand clothing market is growing fast – and not just for adults. Meet the parents changing the way we’ll dress our children in the future

Erick Bouwer’s baby son Joshua was, to use a technical term, a whopper: 4.5kg, or almost 10lb in old money. “That was a big guy indeed, he’s 11 years old now and he still is,” says Bouwer, on the line from Amsterdam. Bouwer and his wife had nested assiduously before Joshua’s arrival, supplemented with presents from friends and family, but arriving home from hospital, they realised that none of the onesies and cute cardigans would fit their new arrival. Bouwer laughs, “We were, like, ‘OK, we’ve got a bunch of clothes here, but I hope we’ve still got the receipts.’”

A decade on, Bouwer’s “personal frustration” became a business, Circos. All parents know there is a relentless churn with children’s clothes, especially when your kids are growing fast: leggings are worn once and come back with holes in both knees; jackets fit snugly for a month before having to be retired. Bouwer, then a pricing strategy consultant, dug deeper. He found that, on average, parents use 280 items of clothing for their child before his or her second birthday. Items are typically worn for around two or three months. After that, only 15% of clothing is donated or recycled. Most of the remainder ends up in landfill.

Going vegan: can switching to a plant-based diet really save the planet?

Posted on by

If politicians are serious about change, they need to incentivise it, say scientists and writers

The UK business secretary, Kwasi Kwarteng, is considering a “full vegan diet” to help tackle climate change, saying people will need to make lifestyle changes if the government is to meet its new emissions target of a 78% reduction on 1990 levels by 2035.

But how much difference would it make if everyone turned to a plant-based diet? Experts say that changing the way we eat is necessary for the future of the planet but that government policy is needed alongside this. If politicians are serious about wanting diet changes, they also need to incentivise it, scientists and writers add.

It’s inspiring hope and change – but what is the IUCN’s green list?

Posted on by

The red list of species at risk is well-known, but the list for protected sites is quietly helping to ‘paint the planet green’

When Kawésqar national park was formed in the Chilean part of Patagonia in 2019, just one ranger was responsible for an expanse the size of Belgium. Its fjords, forests and Andean peaks are a precious wilderness – one of the few remaining ecosystems undamaged by human activity, alongside parts of the Amazon, the Sahara and eastern Siberia.

Chilean officials hope that Kawésqar will, one day, meet the high standards for protected areas laid out by the International Union for Conservation of Nature (IUCN) and make it on to the organisation’s “green list”.

Secrets of a tree whisperer: ‘They get along, they listen – they’re attuned’

Posted on by

Suzanne Simard revolutionised the way we think about plants and fungi with the discovery of the woodwide web. The ecologist’s new book shares the wisdom of a life of listening to the forest

When Suzanne Simard made her extraordinary discovery – that trees could communicate and cooperate through subterranean networks of fungi – the scientific establishment underreacted. Even though her doctoral research was published in the Nature journal in 1997 – a coup for any scientist – the finding that trees are more altruistic than competitive was dismissed by many as if it were the delusion of an anthropomorphising hippy.

Today, at 60, she is professor of forest ecology at the University of British Columbia and her research of more than three decades as a “forest detective” is recognised worldwide. In her new book, Finding the Mother Tree – a scientific memoir as gripping as any HBO drama series – she wants it understood that her work has been no brief encounter: “I want people to know that what I’ve discovered has been about my whole life.” Her moment has come: research into forest ecosystems and mycorrhizal networks (those built of connections between plants and fungi) is now mainstream and there is a hunger for books related to the subject: Peter Wohlleben’s The Hidden Life of Trees and Merlin Sheldrake’s Entangled Life – about the hidden life of fungi – extend her thinking about the “woodwide web”, while the heroine of Richard Powers’s Pulitzer prize-winning 2018 novel The Overstory is said to have been inspired by Simard.
