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.

  • Entire villages swept away after glacial collapse triggers flood in mountainous region popular with trekkers and pilgrims

    Rescuers are searching for nearly 1,400 people, most of them tourists, who are missing after a catastrophic flash flood hit Nepal and Tibet, thundering down valleys, obliterating entire villages and killing at least 356 people.

    Efforts to locate those missing – including hundreds of people from India, the US, UK, Australia and Canada – have been complicated by the destruction of dozens of bridges and almost 25 miles (40km) of roads in the mountainous region popular with trekkers and pilgrims.

  • Environment Agency issues 40 flood alerts across Midlands, Yorkshire and south-east of England

    Dozens of homes have been damaged by flooding and the Met Office had issued warnings for thunderstorms and heavy rain at the end of a summer in which most of England and the whole of Wales was declared in drought.

    The Met Office said thundery showers in England and Wales could cause 75mm of rain to fall in just 12 hours in some areas.

  • Horticulturalists begin moving and propagating plants before the rusty and warped Palm House begins renovation – but some are too tall to save

    It will be a gut-wrenching moment for the horticulturalists at Kew Gardens when some of the magnificent trees in the Palm House have to be felled.

    “There are some sad moments ahead,” said Palm House manager, Will Spoelstra, who knows all the plants inside the cathedral-like greenhouse.

  • Exclusive: utility company wants to draw off tens of millions of litres of water a day from Thames and replace it with treated effluent

    Levels of a toxic “forever chemical” rose to 13 times the legal limit during Thames Water pilots for a controversial multimillion pound water recycling scheme that will pump millions of litres of treated sewage into the River Thames during drought.

    The data from the pilots is in stark contrast to public comments from Thames Water that their water recycling project in south-west London will not harm the riverine environment.

    I travelled to Oslo in the early autumn. It felt like arriving into the future. Or, at least, a fragment of a possible future. I drove north in the quiet digital bubble of my electric rental car. In 2024, Norway became the first country in the world where electric cars outnumbered petrol cars.

    A smooth, pristine motorway unfolded between farmlands and low hillsides of dense green forest. Long tunnels carried the route up above the banks of Lake Mjøsa, Norway’s largest lake. After a little more than an hour, the road curved downward to run parallel to the lakeshore.

  • Bears killed 13 people in Japan last year, as a lack of forest foods increased conflicts. Yet some say the country’s controversial cull could threaten the endangered species

    Every summer, millions of people escape the heat and humidity of Tokyo by heading to the tranquil resort town of Karuizawa in Japan’s Nagano prefecture – just an hour by bullet train from the capital. Here, at the foot of Mount Asama, visitors stroll bamboo-lined pathways, cycle in verdant highlands, and practise the wellness ritual of shinrin-yoku,bathing among the cool hinoki forests. It would be the ideal nature retreat – if it wasn’t for the bears.

    From June to August, bears often move close to Karuizawa, feeding on the mulberries, ants, leaves and cherry blossoms that grow near the town. Unlike nuts, these foods are low in calories, spurring the bears to seek out further sustenance. “They’re more likely to get close to residential spaces to see what they can find,” says Amelia Hiorns, a British zoologist who previously worked with Picchio Wildlife Research Centre in the town. “This combines with the busiest season for tourists.”

  • Investment in climate-resilient irrigation enables this year’s haul to rise 6% on 2025’s already bigger-than-usual yield

    British farmers have faced a sweltering summer tested by heatwaves, wildfires and water shortages – but a bumper berry harvest could prove a rare bright spot.

    With two-thirds of the harvest now picked, this year’s haul is 6% up on last year’s already unusually large crop, according to British Berry Growers (BBG). Volumes of blackberries, blueberries and raspberries picked have been particularly strong, the trade body said.

  • Steel rails warping and signalling equipment failing in metal cabinets are among the problems to be solved

    Tarmac softens in the summer heat, which may cause problems on the roads, but even trains running on steel rails are not immune.

    Railways in the UK are generally designed to operate within a 45C temperature range. The rails expand slightly in the heat, and excessive temperatures can produce “sun kink” with rails warping into S-shapes. The effect is small but the distortion can derail fast trains, so speeds are reduced for safety.

    The climate crisis means “we’re going to have to change everything – the way we live, the way we produce, the way we trade,” France’s veteran radical-left firebrand, Jean-Luc Mélenchon, told the summer congress of his France Insoumise party last weekend.

    The term “climate change”, said Mélenchon – the most likely rival to Marine Le Pen in next year’s presidential run-off, according to one poll this week – may sound “almost reassuring”, but its actual impact will feel like “landing on another planet whenever we leave home”.
