Mrtvi šišmiši u Pitvama, srpanj 2019.

Jutra 24.07.2019. godine, dva mrtva šišmiša koja su ležala jedan pored drugoga na kućnom pragu, uznemirili su dvoje ukućana.

Iskusna veterinarka Susan Corning pregledala je sirota deformirana bića ali nije pronašla vanjske znakove ozljeda. Smrt dvaju šišmiša bez očitih ozljeda vrlo je neobična.

Ovo je dovelo Susan do sumnje da su šišmiši otrovani. Samo pet dana ranije, u petak 19.07., u ranim jutarnjim satima, lokalne vlasti izvele su drugu akciju zaprašivanja Opčine Jelse peretroidnim otrovom u ovoj sezoni. Slučajnost? Susan je, kao znastvenica, sumnjala da su dva događaja povezana. Uzrok smrti ne može se sa sigurnošću utvrditi bez ulaganja truda i novaca u obdukciju. Ali, obzirom da šišmiši jedu insekte, pa tako i komarce, to je mogao biti izvor unošenja otrova. Vlasti tvrde da je korišteni peretroidni otrov, Cipex 10E, “bezopasan za toplokrvna bića”. Ovo je neistinito. Utvrđeno je da aktivni sastojak Cipex-a, cipermetrin, može biti koban za mačke. Vjerojatno isto tako u visokim koncentracijama i za pse, te štetno i za ljude*. Djeluje na živčani sustav. Ako izravno ne ubije ciljne insekte, uzrokovat će nekontroliranu hiperaktivnost. Npr. 14. lipnja 2018. godine, jutro nakon akcije zaprašivanja kroz Pitve, ose su još uvijek imale posla s osinjakom kojeg su izgradile pored ceste, a koje je neizbježno zaprašeno koktelom otrova koje su te godine bile u uporabi. Broj im se, u odnosu na dan prije, smanjio a aktivnost preživjelih bio je nasumičan. Djelovalo je kao da sirota bića, usprkos svemu, pokušavaju raditi najbolje što znaju.

Tako će nakon akcija zaprašivanja otrovani insekti i dalje letjeti uokolo dok ih možda ne pojede ptica, šišmiš ili drugi insekti ostavljajući trag kolateralne štete. Detalji individualnih žrtava, kao što je smrt ovih šišmiša, možda se ne mogu sa sigurnošću znati. Nema sumnje da otrovi naneseni okolišu kroz akcije zaprašivanja doprinose razornom gubitku biološke raznolikosti na Hvaru. Kombinirani učinci pesticida koje lokalne vlasti koriste i onih koje koriste individualni poljoprivrednici i vrtlari uzrokuju ekološku katastrofu.

Šišmiši su jedni od tih, nekoć mnogobrojnih, stvorenja čija se brojka drastično smanjila.

Ljudi ne dolaze u Dalmaciju kako bi pronalazili mrtvu divljinu. Naprotiv, očekuju nezagađeni prirodni okoliš ispunjen divnim stvorenjima prirode. Jedini način da ispunimo njihovu želju jest da izbjegavamo u potpunosti korištenje kemijskih pesticida.

  • Millions in France and across Europe are enduring extreme heat; ‘London is cooking,’ says UN secretary general

    Italy’s health ministry has declared a red heatwave alert in 15 cities including Milan and Rome on Tuesday and said the number would go up to 16 on Wednesday.

    During a red alert – the highest level – the ministry advises people to eat light, stay indoors in the hottest parts of the day and sprinkle themselves with cool water.

  • As hot weather becomes more common, companies and homeowners are coming up with innovative ways to keep properties cool

    When graphic designer Marc Alabaster had a new set of glass doors installed at his West Sussex home eight years ago, he soon realised how they magnified the heat of the afternoon sun.

    “The kitchen was 40-plus degrees,” he said. Then he went on holiday to Spain and saw an apartment building wrapped in louvre-like rows of angled fins or blades that shaded the external walls against the sun.

  • Half a century on, Britain braces for temperatures up to 40C as global heating brings yet more extreme weather

    The summer of 1976 is seared into national memory as one of record heat. Harvests failed, farmers despaired, Britain imported an extra million tonnes of grain, food prices rose by 12%, taps ran dry, and each day, 250 people died from heat-related deaths.

    The heatwave, which began 50 years ago on Tuesday, brought 15 consecutive days on which the peak temperature was above 32C. Half a century later and 32C no longer feels shocking.

  • Researchers say it is ‘quite wild’ to see fires at such high northern latitudes happen so early in the year

    Scientists have expressed concern after two wildfires broke out within a week of each other on the Arctic island of Greenland earlier this month.

    Fires were burning close to Sisimiut, Greenland’s second largest town and a popular tourism centre, on 14 and 15 June, satellite imagery has shown, while a second blaze hit Kujalleq, on the island’s southern tip, on 17 June.

  • The cost of the traditional takeaway has doubled since 2019, and more outlets are trying to tempt customers with cheaper options such as coley, pollack and hake

    In late April, visitors to Harbour Lights in Falmouth, Cornwall, may have raised an eyebrow. The fish and chip shop was in the midst of a “cod-free week”, its owners having removed cod from its menu entirely.

    It was the second time owner Pete Fraser had undertaken the experiment, 15 years after the first. He also removed cod from his shops in Penzance and Helston, replacing it with coley, pollack, hake and hoki. The result was very different. “Some of the feedback we had, which certainly wasn’t what we got when we ran it years ago, is ‘Can you repeat this?’ Before, it was like, ‘Have you guys lost your head’?”

  • Energy secretary hails £100bn milestone in this parliament and says it is ‘only the start of what we want to achieve’

    Ed Miliband has hailed a boost to UK jobs and growth as government data reveals that private sector companies have pledged more than £100bn in investment into the green economy so far in this parliament.

    Offshore wind, solar power and the electricity grid make up the bulk of the planned investment, most of it between 2024 and 2031, which will go to all regions of the UK and comes from a mixture of UK companies and overseas sources including the EU and Japan.

  • The country’s biggest tree – named Heaven Sword of the Da’an River – is a carbon-storing behemoth hosting whole neighbourhoods of wildlife. But this and other giant trees are under threat

    The higher you climb up the gigantic, millennia-old trees of Taiwan’s forests, the more layers of habitat and life emerge. On the forest floor, ferns thrive in the moist shade. Flying squirrels and owls sleep inside the hollow tree trunks. Yellow bell-shaped rhododendron flowers spring from the lower tree canopy. Higher still, dense lichen spread. Up in cloud-drenched branches, a rare, hardy orchid, Bulbophyllum ciliisepalum, can be spotted.

    “In one tree, every species has their preferred location,” says Dr Rebecca Hsu, assistant researcher at the Taiwan Forestry Research Institute. “Every metre the temperature, the wind, the sun, the light is different.”

  • In HBO documentary The Welcome Table, director Josh Fox brings together people from across the world whose lives have been dramatically altered by the climate crisis

    In an age of division, director Josh Fox is hoping to bring people of all kinds together. Specifically, he wants them to share a table – to break bread for a meal, and come together in exuberant song.

    In his new documentary film The Welcome Table, the director of the the Emmy-winning Gasland travels around the world to talk to people at the leading edge of global warming’s effects. The film is part stark warning of the climate crisis, part opportunity to enter into the experience of those living in the corners of the globe. It culminates with the sounds of these individuals together at an enormous table in New Orleans, eating and rejoicing.

  • The colour-coordinated ‘clean girl’ athleisure aesthetic is dead. Now it’s all about mismatched outfits and vintage sportswear

    At first, the goblins came for our downtime. Going “goblin mode” was a lifestyle confined to the home – to the bed, mostly. The “comforts of depravity” it brought (“watching 90 Day Fiancé on mute while scrolling endlessly through social media, pouring the end of a bag of chips in your mouth”, for example) weren’t compatible with doing anything productive.

    Enter the gym goblin. The optics remain much the same – think ancient T-shirts, knackered socks, oversized cardigans – but the setting has changed, with goblincore devotees rising up from unmade beds, Diet Cokes in hand, to hit the treadmill. It’s Diana, Princess of Wales’s oversized college sweatshirts meets Josh O’Connor’s half-tracksuit look for the Disclosure Day press tour – and the polar opposite of the matcha-drinking, Lululemoned “clean girl” aesthetic that dominates fitness circles.

  • Is it an alien? A dinosaur? Is it going to kill us all? Our writer hits Ashdown Forest for the Big One Hundred celebrations – and finds its magic enchanting new generations

    The rolling idyll of heath and forest, spinney and stream that gave us the Heffalump, the Woozle and, most famously of all, Winnie-the-Pooh, has a new fantastical resident. Creeping through the bracken, making strange cooing and purring noises, is a shapeshifting creature with a huge tubular nose and eyes inspired by adders. It shimmies with iridescent patches and the psychedelic purple of flowering heather in high summer.

    Poppet, a puppet made by costume designer Jack Irving and brought to life by a team of 10 award-winning puppeteers, is performing for schoolchildren in Ashdown Forest, East Sussex. The primary school class squeal with delighted fear as the purple apparition transforms itself from caterpillar to bird to munching monster in sinuous moves.
