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.

  • Labour will drop ‘unaffordable’ net zero policies, predicts Reform’s deputy leader

    Richard Tice says voters will turn on government unless energy bills fall

    Labour will back down on its policies aimed at achieving net zero greenhouse gas emissions, the deputy leader of the Reform has predicted.

    Richard Tice, the energy spokesperson for Reform and MP for Boston and Skegness, told the Guardian his party would withdraw from the 2015 Paris agreement that tries to limit global heating to 1.5C.

  • Is the ocean ‘having a moment’? This was the UN summit where the world woke up to the decline of the seas

    A slew of global leaders met in the south of France to discuss the future of the oceans. There was ‘momentum’ and ‘enthusiasm’, but there were critical voices too

    The sea, the great unifier, is man’s only hope … and we are all in the same boat.” So said Jacques Cousteau, the French explorer, oceanographer and pioneering film-maker, who notably pivoted from merely sharing his underwater world to sounding the alarm over its destruction.

    Half a century later, David Attenborough, a year shy of his 100th birthday, followed Cousteau’s trajectory. In the naturalist’s acclaimed new film, Ocean, which highlights the destructive fishing practice of bottom trawling, he says he has come to the realisation that the “most important place on Earth is not on land but at sea”.

  • Trump’s ‘gas-guzzling’ parade will produce planet-heating pollution costs, analysis says

    Among other concerns, the US military parade will produce as much pollution as created to heat 300 homes for a year

    Donald Trump’s military parade this weekend will bring thousands of troops out to march, while dozens of tanks and armored personnel carriers roll down the streets and fighter jets hum overhead.

    The event has prompted concern about rising autocracy in the US. It will also produce more than 2m kilograms of planet-heating pollution – equivalent to the amount created by producing of 67m plastic bags or by the energy used to power about 300 homes in one year, according to a review by the progressive thinktank Institute for Policy Studies and the Guardian.

  • Devon farm footage prompts calls to ban restrictive pens for pregnant pigs

    Welfare of sows confined to farrowing crates was compromised and they displayed signs of extreme stress, experts say

    The use of restrictive pens to temporarily house pregnant pigs in the UK severely compromises their welfare, can traumatise them and should be banned, experts have said.

    Analysis by Animal Equality UK of footage collected from a farm in Devon showed that three pregnant sows in farrowing crates spent more than 90% of their time lying down, with one not standing up at all for a day. On average, between them they bit the bars (a sign of extreme stress) more than once an hour.

  • A map, a myth and a pre-Incan lagoon: the man who brought water back to a drought-ridden town

    When historian Galo Ramón uncovered a long-forgotten pre-Incan water system in Ecuador, he set about restoring it, and helped transform the landscape and livelihoods

    One day in 1983, while studying a hand-drawn map from 1792 of his home town in Ecuador, Galo Ramón, a historian, came across a dispute between a landowner and two local Indigenous communities, the Coyana and the Catacocha. The boundary conflict involved an ancient lagoon, depicted on the map.

    “The drawing depicted a lagoon brimming with rainwater,” says Ramón. Ravines were depicted forming below the high-altitude lagoon, indicating that it supplied watersheds further down – contrary to the typical flow where a watershed feeds into the lagoon.

  • Country diary: A priceless view of a tiger beetle – let’s keep it that way | Ed Douglas

    Burbage, Derbyshire:National parks and the countless marvels they contain should be as they were originally intended – free to all

    There’s a tiger burning brightly in front of me – not in the forests of the night, but on a Derbyshire moor, among the heather and bilberry, and in warm sunshine. It isn’t orange and black, but an iridescent green, and I need to hunker down to reach its level.

    The green tiger beetle is widespread in Britain, and at least to the ants and caterpillars that it predates, it is every bit as threatening as the big cat immortalised by William Blake. Magnified, its fearful symmetry becomes more apparent, its mouth parts ferocious, the dandyish purple of its elegant legs more richly obvious.

  • Why nuclear war, not the climate crisis, is humanity’s biggest threat, according to one author

    Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat

    Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today.

    But what if there was another, greater, human-made threat that could snuff out not only human civilisation, but practically the entire biosphere, in the blink of an eye?

  • Algae bricks and oyster shell walls: what’s on the horizon for eco-friendly building in Australia?

    From fungi-based wall panels to 3D printed bricks made of seaweed, biomaterials are increasingly being used in construction. But how close are they to a home near you?

    The average person might simply see green goop, but when Ben Hankamer looks at microalgae, he sees the building blocks of the future.

    Prof Hankamer, from the Institute of Molecular Bioscience at the University of Queensland, is one of a growing number of people around the world exploring ways living organisms and their products can be integrated into our built environment – from algae-based bricks to straw or fungi wall panels, and render made from oyster shells.

  • Extreme heat poses a danger to players and fans at Club World Cup

    Already controversial because of extra fixtures and Fifa involvement, the new tournament in the US is likely to be played in temperatures above 30C

    Across this weekend, the US National Weather Service is predicting “moderate” heat risk for Miami and Los Angeles. With temperatures likely to exceed 30C, the agency warns “most individuals sensitive to heat” will be affected, a group that contains those “exercising or doing strenuous activity outdoors during the heat of the day”. This weekend is also when the Club World Cup begins.

    When Lionel Messi and Inter Miami kick off the tournament on Saturday night against Al Ahly of Egypt it will be 8pm in Miami and, although the humidity is predicted to be high, the day’s peak temperatures will have passed. Paris Saint-Germain and Atlético Madrid, however, will play under the full height of the California sun on Sunday, with their Group B fixture a midday kick-off at the famously uncovered Rose Bowl in Pasadena.
