As wild wolves return to Europe, one of the first wolves to settle in Denmark has been shot dead in an incident captured on film

One of the first wild wolves to roam free in Denmark for 200 years has been shot and killed, threatening the survival of the species in the country.

Two naturalists who were observing the wolves captured the moment the animal was shot on camera. The film has sparked outrage.

All England Lawn Tennis Club ditches plastic straws for this year’s championships

Wimbledon would not be the same without a thirst-quenching Pimm’s, but this year visitors to the annual tennis championships will be served the beverage without the customary plastic straw.

The All England Lawn Tennis Club announced on Tuesday that no plastic straws would be used in its bars, cafes and restaurants during this year’s Wimbledon fortnight.

Opponents of cull say cost of £1,000 per animal killed means it is wasteful as well as cruel

The cost of policing the controversial badger cull in just one of the 21 zones last autumn approached the £1m mark – the equivalent of more than £1,000 for every animal killed there.

Objectors to the cull described the bill for Cheshire as a horrendous waste of public money and called for the policy to be scrapped on economic as well as animal cruelty grounds.

Waste Not drinks join growing market aimed at preventing huge amounts of misshapen food from being needlessly thrown away

‘Wonky’ fruit and vegetables that would have been thrown away are now being used to make a new range of juices, in one of a number of assaults on food waste.

One of the UK’s largest fresh produce growers has teamed up with a Spanish fruit supplier to create a new product, Waste Not, which will stop edible but visually ‘imperfect’ ingredients such as fresh celery, beetroot and oranges from being dug back into the soil, or used for animal feed. The new juices will go on sale in branches of Tesco.

Titchwell Marsh, Norfolk: Isn’t this a kind of cathedral, an endlessly renewed scene of biodiversity and beauty made by sunlight and fashioned from stardust?

It was wonderful as well as instructive to sit with my younger daughter at the edge of the wetland scrape that is the showcase of the Titchwell Marsh RSPB reserve.

Insect lovers are going to extraordinary lengths to give injured butterflies an extra few weeks of life

New Zealand’s love affair with the monarch butterfly has reached bizarre new heights, with some devotees performing wing transplants on the insects to give them a few extra weeks of life.

Although the butterflies are not classified as threatened or endangered, some lepidopterists have carried out the unusual surgery using techniques picked up from YouTube.

Labor is poised to finally pass the reforms but farmers say the changes will harm the state’s agricultural sector

The Queensland government is expected to pass new land-clearing laws on Tuesday amid fierce protests by farmers on the steps of the state parliament.

The laws are an attempt to rein in soaring clearing rates and restore environmental protections that were scrapped in 2013. The Climate Council estimates bushland more than seven times the size of Brisbane – about 1m hectares – was cleared between 2012 and 2016.

Water supplies in western US will become more precarious amid warming climate

Los Angeles should not exist. The explorer John Wesley Powell warned the US Congress 140 years ago that the American west was a harsh arid land and settlements should be limited to conserve scarce water supplies. The politicians rejected his advice and launched a massive programme of dam and canal construction for irrigation and settlements.

In a gruelling expedition across North America, Powell had seen a dramatic transition from the lush green prairies in the east to the dry lands of the west, and the frontier of this transition was the 100th meridian, an invisible line of longitude passing north-south through North America.

Tree-felling helped trigger ‘hidden collapse’ of mountain ash forests, ecologists say

• Sign up to receive the top stories from Guardian Australia every morning

Melbourne’s water supply is at risk because decades of logging and forest loss from large bushfires has triggered the imminent collapse of the mountain ash forests in Victoria’s central highlands, ecologists have said.

The Victorian government was warned of the likelihood of ecosystem collapse by Australian National University researches in 2015. New research led by Prof David Lindenmayer of ANU, published in PNAS journal on Tuesday, has found the ecosystem has already begun to undergo a “hidden collapse”.

Plan for fund combining taxpayers’ cash and private investment significantly behind schedule, it has emerged

A £400m government plan to build electric car charging points looks likely to be significantly delayed, in a blow to car manufacturers and efforts to tackle air pollution in UK cities.

The Treasury pledged last year to support the switch to zero-emission vehicles with a £400m fund for charging infrastructure. Half of the money was to come from the taxpayer, with the rest matched by the private sector, according to an announcement in the autumn budget.

We want to hear from those who have seen tree felling along tracks and what they think its affect may be on the environment and wildlife

One witness called tree cutting along a track near him as “total mass destruction” as it was revealed that Network Rail launched a secretive felling operation putting millions of trees at risk.

Ray Walton, who saw hundreds of trees being chopped down along the length of track between Christchurch and Bournemouth said: “These trees were mature 30-foot-high trees which have been there for 50 years in some cases and never caused a problem. This went far beyond reasonable management of the trees.”

The Republican Party values polluter wealth over public health

Like Donald Trump and the rest of his administration, Scott Pruitt has been caught up in so many scandals that it becomes impossible to focus on any single act of corruption. It’s difficult to focus on the damage Pruitt is doing to the environment and public health when seemingly every day there’s a new scandal related to his illegal $43,000 phone booth, or use of Safe Water Drinking Act funds to give two staffers a total of $85,000 in raises (and lying about it), or his sweetheart deal on a condo rental from a lobbyist’s wife (and lying about having met with that lobbyist), or wasting taxpayer funds on first class air travel and military jets, and a nearly $3m per year security detail, and bulletproof car seat covers, and a bulletproof desk, and so on.

Number of federal investigations into Scott Pruitt has now risen to 11. Reps. Beyer & Lieu say EPA inspector general will take up an inquiry into the $50-a-night condo rental from the wife of an energy lobbyist.

British and US scientists are to examine the melting Thwaites glacier responsible for 4% rise in sea levels

British and US scientists are to collaborate on a £20m project to examine the Thwaites glacier in west Antarctica, a major glacier that drains an area about the size of the UK.

Lab-grown meat and food-tech startups in the US are showing that applying science to what we eat can save the world and make money

“If you make food that tastes really good, you win,” says Josh Tetrick, with a smile. And winning is crucial, he says, with his company Just in the vanguard of a new sector with an ambitious mission: to use cutting-edge technologies to create food that will take down the meat and dairy industries.

The scope is huge: growing meat in labs, producing creamy scrambled “eggs” from mung beans, or making fish that has never swum in water, or cow’s milk brewed from yeast. The drive is to lessen the colossal environmental damage wrought by industrial farming, from its vast carbon emissions to water pollution and disease.

The Australian Academy of Science and its New Zealand counterpart, the Royal Society Te Apārangi, are launching a 10-year plan to study and name unknown species, warning that a sound understanding of biodiversity is critical in the face of a global extinction crisis. Broadcaster Sir David Attenborough has gotten behind the study, saying, 'We cannot understand the natural world without the taxonomic system.'  He adds, 'I depend on the work of these scientists'

Annual BBC Gardeners’ World Magazine study reports six in 10 people have not seen a hedgehog in their garden this year

Sightings of hedgehogs in gardens have fallen again, with almost six in 10 people saying they have not seen one at all this year, a survey has found.

The world’s oldest known spider has died at the ripe old age of 43 after being monitored for years during a long-term population study in Australia, researchers say.

The trapdoor matriarch comfortably outlived the previous record holder, a 28-year-old tarantula found in Mexico, according to a study published on Monday in the Pacific Conservation Biology Journal.
