Environment secretary Steve Reed urged to bring in ‘full and swift ban’ to protect health of people, wildlife and pets

Wildlife charities have called on the government to ban the sale and use of lead in ammunition used for outdoor shooting.

The Wildfowl & Wetlands Trust (WWT), RSPB, Wildlife and Countryside Link, Chem Trust and Wild Justice have sent an open letter to the environment secretary, Steve Reed, asking for a 18-month transition period for a ban on lead in ammunition sales.

A failure of justice, and draconian Tory law, put Gaie Delap in prison. A failure of government is keeping her there

Gaie Delap will turn 78 on Friday, in Eastwood Park prison, Gloucestershire. Sentenced to 20 months last August for climbing a gantry over the M25 for Just Stop Oil, she was released in November to serve the rest of her sentence on a home detention curfew. But the electronic tag that she was required to wear couldn’t go round her ankle because she has deep-vein thrombosis and it might have risked causing her a stroke. It couldn’t go round her wrist because they couldn’t find a tag small enough, which people keep saying is because she’s frail. Delap hates being called frail. Her wrist is a perfectly reasonable size, 14-and-a-half centimetres. It’s the wrist-tag design that’s wanting. The topsy-turvy world where a government contractor, Serco, can fail and fail again, while a citizen with a social purpose gets called back to prison five days before Christmas to atone for that failure, isn’t even the most absurd thing about this story.

Delap was engaged in direct action to raise awareness about the climate emergency, and the day citizens stop doing that is the day that progressive politics might as well give up and go home. Whatever pretzel twists Labour ministers have to perform to sound as if they’re on the side of the decent, honest commuter, while simultaneously signalling that they understand the scale of the climate crisis, they must surely remember this: the trade union movement, the peace movement, the suffragette movement, the civil rights movement, the climate justice movement; every known movement of change has relied on non-violent action to disrupt the status quo.

Wildfires continued to grow in Los Angeles as overtaxed fire crews battled three major out-of-control blazes that have killed at least five people. The largest and most devastating so far have been the Palisades fire and the Eaton fire, but other blazes, particularly the growing Hurst fire and the Hollywood Hills-based Sunset fire, are continuing to worry Los Angeles residents

Huge wildfires roaring through the Los Angeles area of Pacific Palisades has left the neighborhood in ruins. Resident Sanah Chung left his Pacific Palisades home when a mandatory evacuation order was placed but returned to protect his home from the fire. 'I know this looks pretty stupid, but If I can save one ember from burning down my house, I'll take the risk,' said Chung.

Environment secretary says Labour is aiming for half of food procured for the public sector to come from British farms

Food supplied to the public sector will be monitored for the first time to see how much was grown by British farmers, the environment secretary is to announce.

Steve Reed will speak at the Oxford Farming Conference on Thursday in an attempt to reset his relationship with the farming sector after a tumultuous start in his role. Farmers have been angry about issues including changes to the inheritance tax regime, cuts to EU-derived subsidies and delays to flood payments for submerged farms.

CPS says there is not enough evidence to proceed against Greenpeace activists who blockaded firm’s London office

Criminal charges have been dropped against dozens of people who protested outside the offices of Unilever about plastic pollution.

The Crown Prosecution Service has decided not to proceed against 34 individuals days before their trial was due to start.

There are significant health benefits to trying new things, whatever the activity – and there is always more to learn

There is a paradox to being 20 metres under the ocean. It is a place of calm and wonderment. I am immersed in a foreign world, with a new watery sky above me. There is a sense of serenity, blissful peace as countless colourful fish glide past.

Only the tranquillity is deceiving. As a novice diver, my mind ticks over in hyperdrive. All that stands between me and an agonising fate is the tank of oxygen on my back (and, hopefully, the dive guide’s spare air).

Feeding birds from flat surfaces such as tables could be contributing to spread of finch trichomonosis, says charity

The RSPB has withdrawn flat bird feeders from sale on its website amid warnings they could be spreading deadly diseases to finches.

The charity has said feeding birds from flat surfaces such as tables could be contributing to the spread of illnesses such as finch trichomonosis, which has been blamed for the plummeting greenfinch population.

Exclusive: England and Wales proposals expected to follow Scottish consultation amid fears British farmers are being undercut

Ministers may lift a ban introduced during the BSE crisis on the use of animal remains in feed for farmed chickens and pigs over fears that foreign producers are undercutting British farmers.

A consultation on permitting the use of processed animal protein (PAP) from poultry, pigs and insects has opened in Scotland, and it is understood that proposals will be made for England and Wales in the coming months.

Experts say marsupial mole DNA shows they are closely linked to bandicoots and bilbies and their ancestors likely evolved in a rainforest environment

New research into one of Australia’s most specialised and bizarre animals has revealed the marsupial mole’s biology is as unusual as its appearance.

University of Melbourne researchers, who led the study, extracted DNA from a museum specimen then sequenced and analysed its genome to uncover the evolutionary secrets of the golden-haired species, about which “almost nothing is known”.

These tiny organisms matter. They have been used to map dark matter and improve transport networks, and they’re living all around us

A few years ago, I started looking at the underside of logs and it changed my life. I found a secret carnival of the most bodacious and interesting organisms I had ever seen. Bubbles of candy-pink gloss on stilts (Comatricha nigra), bunches of rainbow iridescence on toffee strings (Badhamia utricularis), bouffants of raspberry parfait (Arcyria denudata) – and those are just a few that have appeared on bits of wood in our urban garden.

Slime moulds, or myxomycetes, spend part of their life cycle as what are known as fruiting bodies – which look a bit like tiny mushrooms, hence why they were once classified as fungi (they’re actually in the kingdom Protista). Often you will find them, at this stage, in a colony – or, well, I’d suggest galaxy, sweetshop or funfair would be more accurate for a collective noun.

Diminutive bird breeds in Alaska and Arctic Canada and sightings in Britain are rare enough to attract a crowd

If you’d asked me which rare bird I might see in Somerset in early January, the least sandpiper would have been very low on my list. Yet on a fine, bright, chilly morning here it was: running along the edge of the water like a clockwork toy, probing the mud for food with its stubby bill.

This species is well-named. It is the world’s smallest wading bird, just 13-15cm long and weighing less than 30 grams – about the same as a house sparrow. Even its scientific name, minutilla, is Latin for “very small”. Standing next to a dunlin and a teal, it made them look enormous.

Steve Reed to announce focus on making farming ‘more profitable and sustainable’ at Oxford Farming Conference

The government is aiming to reset its relationship with farmers with what it describes as a “new deal” for the industry.

Farmers have protested in their tens of thousands after controversial changes were made to agricultural inheritance tax and the EU-derived subsidy scheme.

Campaigners welcome move but say success depends on enforcement and global agreement on a treaty

Thailand has banned plastic waste imports over concerns about toxic pollution, as experts warn that failure to agree a global treaty to cut plastic waste will harm human health.

A law banning imports of plastic waste came into force this month in Thailand, after years of campaigning by activists. Thailand is one of several south-east Asian countries that has historically been paid to receive plastic waste from developed nations. The country became a leading destination for exports of plastic waste from Europe, the US, the UK and Japan in 2018 after China, the world’s biggest market for household waste, imposed a ban.

Waterways can protect biodiversity, help with water security and keep cities cooler, says Canal & River Trust

Protecting the UK’s canals is crucial for improving the nation’s resilience to climate change, campaigners have said.

A report by the Canal & River Trust charity found canals could play a “critical role” in biodiversity, decarbonisation and climate adaptation.

Toxic male mosquitoes will poison females with their semen in a new population control method developed by Australian researchers.

The method involves genetically engineering males to produce spider and sea anemone venom proteins, which they inject into females during mating, reducing their lifespan.

‘Future homes standard’ will not mandate replacing boilers with environmentally friendly alternative

The government is to scrap the 2035 ban on gas boilers in its new housebuilding standards.

The previous Conservative government had laid plans to phase out gas heating for homes by banning the sale of new gas boilers by 2035, so people replacing their gas boilers after that date would instead have to buy a heat pump or other environmentally friendly way of heating homes.

Exploring the aberration, absurdity, madness and ingenuity of skiing, an activity that raises both questions and concerns despite its global success. It continues to fascinate and intrigue in the face of social and environmental upheavals. There are more than 2,000 resorts scattered across the world, attracting hundreds of millions of skiers, but there are also profound questions about its future amid climate challenges and societal changes

While the EU and US hesitate, the UK can become world leader in this burgeoning – and cruelty-free – innovation

If the pet food industry were a country, it would rank as the world’s 60th biggest emitter of carbon dioxide. In countries such as the US, researchers estimate that pet food accounts for about a quarter of total meat consumption. And as the number of pets grows, the environmental impact looks set to increase. But the British government may have unlocked a solution. This year, the UK became the only country in Europe to approve the use of lab-grown meat in pet food.

Lab-grown meat may sound futuristic, but the process is actually straightforward. It starts with the harvesting of a small number of animal cells, then the cells are fed essential nutrients to help them replicate and grow, similar to a yeast culture on a petri dish. But unlike a whole living animal, there are fewer limitations on size, there are no welfare concerns, and the setup does not require such vast land, water and energy resources.

Ports including in Saudi Arabia and the US projected to be seriously damaged by a metre of sea level rise

Rising sea levels driven by the climate crisis will overwhelm many of the world’s biggest oil ports, analysis indicates.

Scientists said the threat was ironic as fossil fuel burning causes global heating. They said reducing emissions by moving to renewable energy would halt global heating and deliver more reliable energy.
