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.

  • Weighed down by underinvestment and uncertainty, staff at Maple Lodge just want to get on with the job

    It is a grey day in a wet weekbut one of Thames Water’s neglected plants is still coping. Wastewater is being pumped into the vast Maple Lodge sewage treatment centre in Rickmansworth, just off the M25, at a rate of about 3,000 litres a second, within capacity.

    The site manager points out the first-line screens that catch everything that will not pass through a 5mm filter. A “sheep” – a bundle of wet wipes, sanitary pads, cotton buds, condoms and indigestible bits of sweetcorn – is rotating at one edge. Credit cards and false teeth have been known to end up here.

  • Exclusive: Documents show Andrea Jenkyns asked how she could help firm after major gas find in Lincolnshire

    Lincolnshire’s Reform party mayor, Dame Andrea Jenkyns, has courted the head of an American oil and gas dynasty in the hope of bringing fracking to the county, the Guardian can reveal.

    Egdon Resources, a British subsidiary of the US fracker Heyco Energy, announced a major gas discovery in Lincolnshire’s Gainsborough Trough last year. Jenkyns, who became the first mayor of Greater Lincolnshire in May, reached out personally to the company asking how she “could help with your recent gas find in my county”, according to records released by the mayoral authority in response to a freedom of information request.

  • Taster days and training are offering teenagers an escape from a future of part-time, seasonal work – and giving a boost to a declining industry

    It’s mid-morning on a rare calm day in Newlyn, Cornwall. Will Roberts is back at the quayside with a catch of mackerel to unload, having set off from the harbour before dawn. At 22, he is something of a rarity here, one of a handful of young fishers running his own small commercial boat from the port.

    “It’s a magical feeling when you set out in the dark, with no one else around, and see the Milky Way in the sky above you,” he says. “I couldn’t imagine working in an office or somewhere indoors, and not be surrounded by all of this.”

  • South-western France could hit 25C, while a powerful Nor’easter is forecast to bring blizzards to Boston

    An early taste of spring is on the way for millions across northern and western Europe this week. Temperatures could climb close to a near record-breaking 20C (68F) in parts of Belgium, Germany, Luxembourg and the Netherlands, with south-western France approaching 25C on Wednesday.

    The warmth is being driven by a highly amplified synoptic pattern, featuring a region of low pressure over the Atlantic and strong high pressure over central Europe. The setup will allow exceptionally mild air to spread across much of the continent, with temperatures in some places rising to 10-15C above the seasonal average.

  • Wold Newton, East Yorkshire: On a dreary day in a nondescript field, I visit the site where a 4.56 billion-year-old bit of space rock came to Earth

    On a low rise, beyond a screen of trees, behind a small holiday park in the Yorkshire Wolds, a brick obelisk stands incongruously at the edge of an otherwise nondescript field. It bears a plaque inscribed as follows: “Here, on this spot, Decr. 13th, 1795 / fell from the Atmosphere AN EXTRAORDINARY STONE / In breadth 28 inches / In length 36 inches…”

    The words are carved in a variety of enthusiastic fonts, with the opening “Here” given particularly earnest flourish.The extraordinary, extraterrestrial stone in question is the Wold Cottage meteorite, the first from anywhere to be widely recognised as a rock from outer space. After a 4.56bn-year journey, it now rests in the Treasures Gallery of the Natural History Museum.

  • The Belgian ceremony attracts beekeepers from the Netherlands, France and Germany keen to boost dark bee numbers and stop the spread of the hybrid honeybee

    Every summer, 1,000 virgin queens descend on the Belgian town of Chimay. During the “wedding flight”, a male attaches to the female. His endophallus (penis equivalent) is torn off and he falls to the ground and dies. Mission accomplished.

    Beekeepers come and pick up their fertilised queens in small colourful hives, driving them back home, sometimes more than 300km away. They will use the genetic material gathered in south Belgium to build new colonies in the Netherlands, France and Germany.

  • Even as weather extremes worsen, the voices calling for the rolling back of environmental rules have grown louder and more influential

    In the timeless week between Christmas and the new year, two Spanish men in their early 50s – friends since childhood, popular around town – went to a restaurant and did not come home.

    Francisco Zea Bravo, a maths teacher active in a book club and rock band, and Antonio Morales Serrano, the owner of a popular cafe and ice-cream parlour, had gone to eat with friends in Málaga on Saturday 27 December. But as the pair drove back to Alhaurín el Grande that night, heavy rains turned the usually tranquil Fahala River into what the mayor would later call an “uncontrollable torrent”. Police found their van overturned the next day. Their bodies followed after an agonising search.

  • Armed groups and a state-owned refinery’s oil leaks have displaced Barrancabermeja’s fishing community and poisoned a paradise once full of manatees and jaguars

    Standing on her wooden canoe, a machete in her hand, Yuly Velásquez hacks away at reeds matted with blackened sludge. Close by, a burst oil pipe has released a slick of crude into the San Silvestre wetlands in Barrancabermeja, Colombia’s oil city, choking the water and its wildlife.

    “The destruction is immense,” says Velásquez, president of Fedepesan, a sustainable fishing organisation. “For the fish, the animals and flora, it means immediate death.”

  • In an edited extract from her latest book, Hazel Sheffield sets out a new blueprint for community stewardship

    It was a Saturday in February 2020 when the flood came. It had been a wet winter, so wet it seemed that before the month was out, the brown trout of the River Taff might be washed clean out into Cardiff Bay before the fishing season had even begun. But this is Wales. People are used to a spot of rain. No one realised how bad it would get.

    For two days, it hammered on the windows of the houses at the top of the South Wales Valleys, where people tucked in their children before a sleepless night. It poured into the rivers at the bottom. By the time the rain departed again, many people would be standing in water up to their knees.

  • Rivers drained dry to create artificial snow, a forest cut down for the bobsleigh track – IOC’s claims to prioritise sustainability at Milano Cortina exposed

    On the foothills of the mountains, by the banks of the river in Cortina, there was a forest. It was full of tall larch trees. Arborists said the oldest of them had been there for 150 years and dendrologists that it was unique because it was unusual to find a monocultural forest growing at such a low altitude in the southern Alps.

    The locals knew mostly it was the place where the old wooden bobsleigh run was, where you went on your walks in summer or autumn, or when you wanted to play tennis on the small courts built near the bottom. They called it the Bosco di Ronco and it isn’t there any more.
