More than 200 marine species, including deepwater sharks, leafy sea dragons and octopuses, have been killed by a toxic algal bloom that has been affecting South Australia’s coastline since March.

Nearly half (47%) of the dead species were ray-finned fish and a quarter (26%) were sharks and rays, according to OzFish analysis of 1,400 citizen scientist reports.

Long-term reform is not going to be easy, but we have now wasted 15 years and everyone has lost, especially the natural world

• Get Guardian Australia environment editor Adam Morton’s Clear Air column as an email

Long overdue reform of national environment laws is unfinished business for the 48th parliament and the re-elected Albanese government.

Senator Murray Watt, a Queenslander, is well respected within the government and has a reputation for taking hard decisions and bringing together diverse stakeholders. Both of these attributes will be at a premium if the minister is to succeed where others have not.

Sustainable farming initiative is part of payment package that replaced EU’s common agricultural policy

• UK politics live – latest updates

Ministers wrongly refused nature funding to 3,000 farmers in England when they shut the post-Brexit subsidy scheme, the government has admitted.

There was anger earlier this year when the environment secretary, Steve Reed, suddenly paused a key post-Brexit farming payments scheme with little information about what would replace it and when.

Exclusive: Campaigners call for energy profits levy to be made permanent to enable ‘just transition’ from fossil fuels

Making permanent the UK’s windfall tax on oil and gas producers would generate enough cash to enable North Sea workers to move to green jobs, research has found.

Cutting current subsidies to fossil fuel producers would free up yet more funds to spend on the shift to a low-carbon economy, according to the report.

Hundreds of jobs may be at risk, say heads of ABF Sugar and Ensus, as Starmer agrees to remove tariffs on US ethanol

• Business live – latest updates

The British bioethanol industry could collapse as a result of Keir Starmer’s trade deal with Donald Trump, industry bosses have said.

The bosses of ABF Sugar and Ensus, the companies behind almost all of the UK’s production capacity of bioethanol – a petrol substitute produced from agricultural products – have said hundreds of jobs in north-east England and Yorkshire could be at risk as a result of the deal.

Fourth most important food crop in peril as Latin America and Caribbean suffer from slow-onset climate disaster

The climate crisis is threatening the future of the world’s most popular fruit, as almost two-thirds of banana-growing areas in Latin America and the Caribbean may no longer be suitable for growing the fruit by 2080, new research has found.

Rising temperatures, extreme weather and climate-related pests are pummeling banana-growing countries such as Guatemala, Costa Rica and Colombia, reducing yields and devastating rural communities across the region, according to Christian Aid’s new report, Going Bananas: How Climate Change Threatens the World’s Favourite Fruit.

Sir Adrian Montague’s appearance on Tuesday offers perhaps the last chance to scrutinise utility’s dealings

Hurrah, Sir Adrian Montague, the chair of Thames Water, is scheduled to make another of his rare public appearances. On Tuesday, he will be at the environment select committee, the forum where 18 months ago he gave a strong signal that the company’s financial crisis was even worse than feared.

The shareholders, in their standoff with the regulator over bills, wanted to know the business was “investable”, said Montague. Three months later those investors decided it wasn’t and refused to put in another penny. That forced the current refinancing contest that has seen KKR, the US private equity group, chosen as preferred bidder at the end of March.

Exclusive: Decision on whether to work with turbine maker being overseen by ministers after British Steel rescue

Ministers are weighing up proposals for a Chinese company to supply wind turbines for a major offshore windfarm in the North Sea.

The government is in discussions with Green Volt North Sea over whether Mingyang, China’s biggest offshore wind company, should supply the wind turbines. Mingyang has emerged as the preferred manufacturer, but the company has sought advice from ministers on whether to proceed.

Conservationists call for more funding and warn of danger to ‘cherished’ native species, from water voles to ladybirds

Less than 1% of the government’s biosecurity budget goes on tackling invasive species, despite the danger they pose to British wildlife, figures suggest.

Conservationists warned the funding to address non-native plants and animals was failing to match the risk they posed to “cherished” native species, from water voles to ladybirds, as well as to waterways, homes, businesses and local green spaces.

Healthy peatlands can help tackle the climate crisis but degraded peat emits carbon and contributes to global heating

New mapping of England’s peatlands has revealed that 80% of the habitats are dry and degraded.

Scientists mapped England’s peatlands and peaty soils for the first time using satellite imagery, artificial intelligence and in-depth data analysis to create the most complete map to date, the Department for Environment, Food and Rural Affairs (Defra) said.

Workers at farm owned by UK’s biggest pig meat producer Cranswick filmed killing piglets by banned ‘blunt force trauma’

• Warning: graphic content

Tesco, Sainsbury’s, Asda and Morrisons have suspended supplies from a Lincolnshire pig farm linked to abuse against pigs.

Secretly filmed footage has shown farm workers at Northmoor Farm appearing to grab piglets by their hind legs and smashing them on to the hard floor – a banned method of killing known as blunt force trauma or “piglet thumping”.

The Danish drama is piercing in its ordinariness. In the real world, the climate crisis worsens and authoritarians take charge as we calmly look away

The climate crisis has taken a new and frightening turn, and in the expectation of disastrous flooding, the entire landmass of Denmark is about to be evacuated. Effectively, the country will be shutting itself down and sending its 6 million people abroad, where they will have to cope as best they can. Huge numbers of northern Europeans are therefore being turned into refugees: a few might have the wealth and connections to ease their passage from one life to another, but most are about to face the kind of precarious, nightmarish future they always thought of as other people’s burden.

Don’t panic: this is not a news story – or not yet, anyway. It’s the premise of an addictive new drama series titled Families Like Ours, acquired by the BBC and available on iPlayer. I have seen two episodes so far, and been struck by the very incisive way it satirises European attitudes to the politics of asylum. But what has also hit me is its portrayal of something just as modern: how it shows disaster unfolding in the midst of everyday life. At first, watching it brings on a sense of impatience. Why are most of the characters so calm? Where are the apocalyptic floods, wildfires and mass social breakdown? At times, it verges on boring. But then you realise the very clever conceit that defines every moment: it is really a story about how we all live, and what might happen tomorrow, or the day after.

The writer and journalist Dorian Lynskey’s brilliant book Everything Must Go is about the various ways that human beings have imagined the end of the world. “Compared to nuclear war,” he writes, “the climate emergency deprives popular storytellers of their usual toolkit. Global warming may move too fast for the planet but it is too slow for catastrophe fiction.” Even when the worst finally happens, most of us may respond with the kind of quiet mental contortions that are probably better suited to literature than the screen. Making that point, Lynskey quotes a character in Margaret Atwood’s novel The Year of the Flood: “Nobody admitted to knowing. If other people began to discuss it, you tuned them out, because what they were saying was both so obvious and so unthinkable.”

Study finds dietary fiber effectively cuts levels of two most common and dangerous Pfas, with more research planned

• Sign up for the Detox Your Kitchen newsletter

Consuming higher amounts of fiber reduces levels of toxic Pfas “forever chemicals” in human bodies, a new peer-reviewed pilot study suggests.

The research found fiber most effectively reduces Pfos and Pfoa, among the two most common and dangerous Pfas. Each can stay in bodies for years, and federal data shows virtually everyone has the chemicals in their blood.

As I stood there, awed by how disgusting and wasteful our species is, I realised that everyone needs to see this

Like all the best things in life, this story starts with an argument about bins. Admittedly, I could do better at recycling. I can try to chalk this up to having read too much about how all our plastic waste ultimately ends up in landfill sites in the poorest parts of south-east Asia. But I’m also lazy and so well-acquainted with cognitive dissonance that I could probably cry over the death scene in Bambi while comforting myself by chowing down on a giant haunch of venison.

My partner, Leo, is the total opposite: diligent and principled. Which is why she finally lost it with me for failing to put a plastic yoghurt tub in the recycling. I went on the defensive, citing half-imagined reports about megadumps in the Philippines and inescapable doom. She retaliated by booking us on an educational tour of Southwark Reuse and Recycling Centre.

As an oceanographer, I study how the ocean shapes our world. For Australia and other nations, the lesson is urgent

Antarctica is often viewed as the last truly remote place on Earth – frozen, wild and untouched. But is it really as untouched as it seems?

This vast frozen continent is encircled by the Antarctic Circumpolar Current, the only current in the world that connects all the oceans, showing how closely linked our planet really is.

The state government is aware of koala welfare problems but says it has ‘no cost-effective’ solutions

Thousands of koalas are being displaced each year as blue gum plantations are cut down in Victoria, worsening overcrowding in nearby forests and exacerbating the risk of injury and death during bushfires.

An estimated 42,500 koalas live in blue gum plantations in south-west Victoria, data shows. Between 8,000 and 10,000 hectares of plantation are harvested each year, making thousands of koalas homeless.

There is an appetite in this country for policy that will change lives. What is more fundamental than the water we use and bills we pay?

• Clive Lewis is the Labour MP for Norwich South

In the wake of a brutal set of local election results, MPs from across the Labour party are trying to establish what went wrong. To me, it’s very clear that this was no fluke: it was the entirely foreseeable outcome of my party’s approach to Reform UK. And as the party moves forward and prepares to face Reform at future elections, it’s key that we learn the right lessons.

From flip-flopping on climate commitments to framing disabled people as part of the undeserving poor, Labour thus far hasn’t challenged Reform’s worldview – it has legitimatised it. However, there are some perhaps surprising areas where Labour isn’t copying Reform: public ownership of water for one.

Sap-sucking insects top list of queries to gardening charity after causing significant harm to plants

Aphids are plaguing gardeners this spring due to the warm weather, with higher numbers of the rose-killing bugs expected to thrive in the UK as a result of climate breakdown.

The sap-sucking insects have topped the ranking of gardener queries to the Royal Horticultural Society, with many of its 600,000 members having complained of dozens of aphids on their acers, roses and honeysuckle plants.

Findings show for first time how plastic chemicals throw off the body’s internal clock by up to 17 minutes

Chemicals in everyday plastics may disrupt the body’s natural 24-hour sleep-wake cycle and circadian rhythm in a way similar to coffee, which increases the risk of sleep disorders, diabetes, immune problems and cancer, new in vitro research shows.

The study looked at chemicals extracted from a PVC medical feeding tube and a polyurethane hydration pouch, like those used by long-distance runners. PVC and polyurethanes are also used in everything from kids toys to food packaging to furniture.

Scientists fear early emerging insects may fall out of sync with pathogens, predators or availability of food

Midsummer butterflies are on the wing in early May after a sunny spring prompted one of the most advanced seasons for Britain’s Lepidoptera on record.

The Lulworth skipper – usually found in June and July – is flying at Lulworth Cove in Dorset, the chequered skipper emerged in April rather than mid-May in Scotland and the first swallowtail, which is most common in mid-June, was spotted in Norfolk on 1 May.
